Cover your ears! Amsterdam Dance Event goers invited to hearing pill tests

Anyone will tell you, we are the first to champion hearing protection and the progress to hearing health. With all the latest technological developments, we are looking at a new era of hearing health. This supplement is supposed to ‘be beneficial for reducing hearing loss due to aminoglycosides and overstimulation’ and if the test come back positive we might see further advancement in this field.

The Amsterdam Dance Event is about more than top DJs and partying, reports Senay Boztas



As 375,000 people prepare themselves for big noise at the five-day Amsterdam Dance Event, a business has asked them to listen up: Hearing Health Science is looking for recruits to trial its ‘protective’ hearing pills.

The Amsterdam-based business, co-founded by a leading inner ear neuroscientist from the University of Michigan Dr Josef Miller, has joint US patents on a dietary supplement combination including vitamins A, C, E and magnesium.

Studies have shown some evidence that this ACEMg supplement ‘can be beneficial for reducing hearing loss due to aminoglycosides and overstimulation,’ according to a report in Nature magazine in February, co-authored by Miller. Hearing Health Science hopes to begin producing pills next year and is taking pre-orders at the festival, at a cost of €30 for a four-week supply.

Pilots



It is also looking for volunteers to take part in pilot tests, signing up recruits at the Amsterdam Dance Event, which this year is putting on 2,200 acts in 140 venues and expecting a peak of numbers.

Barry Seifer, co-founder and chief executive of the company explained: ‘The pill we are bringing to market is safe, and you cannot test in the lab by giving someone a problem and then offering to cure it. If you are going to do epidemiological research on something like this â€" noise â€" you have to do it in the real world, where the problem happens. This is a great place to do that research.’

The company is planning pilot tests with volunteers from the ADE â€" although Seifer said they won’t be handing out pills at the door â€" and hopes to invite some of these to a modified crossover study. This should take place when the ‘festival’ season begins from March next year, and subjects will be followed for a period, taking the drug and a placebo at different times, and measuring their hearing through a special app developed at the University of Michigan.

Tinnitus

‘We’ve done it once with a tinnitus trial and now we want to do real-world studies in the music industry,’ says Seifer. ‘Our initial idea was to recruit 20 or 30 people but we have such intense interest that I think we’ll have 500 who sign up. We would love to be able to give this to people now because millions need help, but we’re not quite there yet. We’re not going to stand at the doors and hand out pills.’

A spokesman for ADE said the festival has worked with Hearing Health Science in the past and invited it to speak at an event on Thursday. ‘We believe you need to protect your hearing and welcome initiatives in this field,’ he said. ‘HHS has been working on this hearing protection for a long time and at ADE we are always looking out for innovations in the field of (electronic) music…we also actively offer earbuds to visitors.’

Highlights of the event this year include Afrojack, Hardwell and Martin Garrix, and the festival expects 3% more clubbers, with a steadily pattern of growth over its 10 years. House music and techno are currently the most popular genres.

Seifer adds: ‘We would never tell you to turn the music down. Entertainment goers are trying to keep the music to lower volumes and encourage people to use filters and party plugs â€" these are good. The problem is that this is supposed to be fun!’

London Gatwick Airport deploys new radio system from Motorola Solutions

Back in the day, around 2006, the Heathrow and Gatwick radio systems were the envy of many, many businesses, a cutting-edge Motorola analogue trunking system with individual and group setup, that could broadcast messages out across the site or talk to individual radios, something that is taken for granted these days with our digital systems. The Gatwick system has been upgraded and been given the digital touch.



US-based Motorola Solutions, along with its authorised channel partner Servicom, has debuted its new digital mobile radio (DMR) system, Mototrbo Capacity Max, at London Gatwick Airport.

Designed to provide enhanced voice and data communications, the newly installed system connects 1,300 people in the airport's airside and groundside teams.

Mototrbo Capacity Max will also double the capacity of Gatwick’s current analogue network.

Various applications, such as TRBOnet PLUS and iBeacon, were given along with Mototrbo Capacity Max to improve its data performance.

TRBOnet PLUS is a dispatcher application that allows voice recording, mapping and event logging in the control room, while the iBeacon indoor positioning application sends alerts to individual radios based on location.

Gatwick Airport IT project manager Simon Telling said: “We chose Motorola Solutions’ Mototrbo Capacity Max system not only for how resilient and secure it is, but because of the flexibility it offers us now and into the future.

“We have experienced significant growth over the past decade and we are now approaching the limits of our previous analogue system.

“Migrating to scalable, digital communications will double our capacity and bring new capabilities that will help us improve efficiency and safety for staff, retail partners and passengers across the airport.”

The new Motorola solution will also enable Gatwick’s central controllers to send off the closest employee to an incident, saving time.

The airport recorded more than 4.6 million in passenger traffic in July.

Motorola Solutions’ digital two-way radio technology enhances mission-critical communications at Munich airport

Motorola solutions are a company well known for their robust two way radios and for building world class communication structures. Improving on the current TETRA system with an IP dispatch console and piloting the WAVE system, that allows a phone app to connect to the radio system, for communicating of site. You can read more about what Motorola are doing for Munich below and you can find the original article here.

Motorola Solutions has received an order to implement a comprehensive update and extension of its existing TETRA digital two-way radio system at Munich Airport.

The newly modernized communications infrastructure ensures greater connectivity, interoperability and collaboration between various business and operational functions at Germany’s second largest airport. Motorola Solutions will also provide services for ensuring smooth operations.

Within the framework of the TETRA radio network refresh, Motorola Solutions is equipping the airport with a new MCC 7500 IP Dispatch Console. The comprehensive, scalable solution enhances the IP architecture to ensure optimum call set up and availability. It will also allow Munich Airport to expand its communications infrastructure in the future without interrupting existing services. As well as this, Motorola Solutions will implement two TETRA base stations for improved TETRA radio coverage in the terminal buildings.



Alongside the improvements to the TETRA system, the airport has started a pilot project for the potential introduction of Motorola Solutions’ broadband push-to-talk (PTT) platform WAVE. The goal of the installation is to ensure that airport staff can communicate, no matter which device or infrastructure is being used. The powerful PTT solution WAVEâ„¢ Work Group Communications provides airport authorities with secure and reliable communications beyond TETRA radio â€" including broadband devices and networks â€" to enable greater workforce connectivity, interoperability and collaboration. WAVE connects the TETRA system used by administrative staff with service management employees who join the broadband platform via smartphones, computers, other radios or telephones, meaning that staff across the airport can communicate with one another from virtually any location.

“We have been working with Motorola Solutions’ TETRA two-way digital radio system since 2007,” said Michael Zaddach, head of the IT service division at Flughafen München GmbH. “The update of our TETRA infrastructure enables us to further improve our communications in airport operations and make our processes even more efficient.”

“We are collaborating closely with Munich Airport to provide a future-proof TETRA digital two-way radio network,” said Klaus-Dieter Drossel, sales director for key accounts, Motorola Solutions Germany GmbH. “We are also pleased that Munich Airport is testing our broadband push-to-talk platform WAVE, and we are certain that it will enable airport staff to work together more closely, no matter which device or network they use.”

Imtradex Aurelis Handheld Microphones Future Proof to fit all Purposes

We call these Remote Speaker Mics (RSM) and they have come in all different shapes and sizes over the years. Normally a staple of the emergency services, but we have seen a upsurge in general radio users using RSM’s. So it comes as no shock to us that a pro-active company like Imtradex has designed one to suit the needs of the masses.

What was originally developed as a handheld microphone for digital radios, has blossomed over the past few years to an essential equipment accessory for digital radio standards of emergency service: The Aurelis hand microphone from Imtradex.

Meanwhile with the Aurelis, the specialist for critical communications, have a whole series of hand microphones on the market, all adapted to the specific challenges of the communication in critical applications of security agencies, fire departments, dispatch and emergency services. The Aurelis series addresses the different needs of the user: based of the basic model Aurelis Base, Imtradex manufacture customized versions that are specially tailored to the range of functions that meet the customer’s requirements.

All the Aurelis hand microphones have a send button, a microphone and high quality speakers. “All devices contain a cable attachment and also the possibility to connect external audio accessories” adds Ralf Kudernak, CEO of Imtradex. Depending on the radio, different data applications can be integrated, so can ex. on the model Aurelis AudioDis, information be displayed on the LCD display.

“The youngest member of the family is the Aurelis USB handheld microphone, which is designed for connection to computer-based communication system, especially for control centers” informed Ralf Kudernak. “The USB interface gives the easy integration and can be connected independently to each operation system and used with existing hardware. With the development of the Aurelis USB, we followed the desire of several control centers, which wanted to use a handheld microphone which you can also hang at the table of the workplace” said Kudernak.



In terms of digital communication, security and flexibility the innovative ultra-lightweight Aurelis Nexus PTT set new standards. It was specially designed for fire fighting. Thanks to it extra large PTT, with short sensing path and exactly defined pressure point, the operation with use of working gloves is possible.

The user can also be flexible in their choice of radio and headset: All Aurelis handheld microphones can be combined, not only with many headsets, for example with the monaural neckband headset from the NB Series. They are convenient and safe to wear, provide a maximum safe mobility and provide an excellent voice quality. Imtradex can also build them with the different connectors required, so they can easily be connected to different digital radios. All Aurelis handheld microphones have a robust plastic housing. Is splash-proofed and protects the device against dust and against temperature influences, so they can be reliably used in a temperature range from -30 to + 70 degrees Celsius. The 180 gram lightweight Aurelis handheld microphones are also available in different colours and optionally equipped with a car holder or cloth clip.

What's the Best 2 way Radio For a Long Range

When choosing the best 2 way radio, it is important to note that doesn't matter which brand you pick. Whether you pick kenwood, Motorola, Icom, Hytera or any other brand, you should know that they all feature the same technology. Well, you might have noticed that most consumer radios tend to advertise a range that's up to 30 miles. Truth is, the consumer FRS/GMRS radios don't even provide anything close to the advertised maximum range; the range that a two way radio advertises is normally the range that a radio can get in the ideal condition. The ideal condition is clear line of sight like from the mountain top to the valley below; without any interference or obstructions.

Two way radios generally operate within VHF (that is Very High Frequency; 130 to 174MHzz) and UHF (that is, Ultra High Frequency; 420 - 470 MHz)) wave bands. Unlike the frequencies that are below 2MHz, the waves in these particularly higher frequencies travel in a straight line (also known as line of sight signal), and generally can't travel beyond your horizon. This basically means that distance to your horizon, is the actual maximum range for your 2 way radio; that is without the use of any additional equipment to boost the signals.

VHF waves (about 5 feet wide), are generally longer than the UHF waves, and they're most commonly used for long range/distance communication. If VHF waves and UHF waves were both transmitted in ideal conditions without any barriers, the VHF waves would travel nearly twice as far; as a general rule, the lower the wave frequency, the greater the distances it can travel.



Key to transmitting the radio waves for a long distance along the VHF waves is keeping the receiver and the transmitting radio above all possible obstructions or interfering objects. The VHF frequencies (because of the length of their waves), cannot transmit through some objects like walls, dense forests and hills. Typically, the transmissions which are sent along VHF waves are received and also sent high above earth's surface. VHF two way radios normally work better when there is a clear line of sight between the receiver and the sender. VHF 2 way radios are commonly used in marine and aviation communications where signals get sent across the open water bodies or between the ground and the sky. Television and FM radios also use the VHF frequencies where the signals are sent and also received high at the top of towers which are spaced all over the towns, cities and counties. VHF band walkie talkies are also perfect for landscaping, open fields, golf courses and also for outdoors security situations where there is less obstruction.

Though VHF can travel much farther, it doesn’t mean it is the better option. Reason is because of the differences between how the VHF and the UHF signals tend to react around buildings or structures. As you will find out below, UHF signals are shorter than VHF, and this is very important when you're in or around buildings.

UHF doesn't travel as far as the VHF, but has higher bandwidth occupation. One major advantage of UHF over the VHF, is that the antenna can actually be much smaller when its' used on the higher frequencies. Sometimes, a base antenna might be needed for radios using VHF frequency, but a small antenna on a radio can be comfortably used for the UHF frequency. Moreover, there are a lot more frequencies which are available when using UHF; this can be very useful in the areas which have a high population density.

The UHF radio waves are much shorter than the VHF radio waves (measuring at about one and half feet); the short length of UHF radio waves typically decreases distances at which the signals can get transmitted. This means that the line of sight between the receiver and the sender is much shorter in length with UHF waves. That being so, you should know that transmission of the UHF waves is usually high enough such that it can penetrate through the building walls and the urban outdoor settings. This is the reason why UHF two way radios usually work best for those who intend to use them in and around buildings and urban areas. A UHF walkie talkie with adequate power and a good sized antenna can reach further into the building, and push through steel, wood, concrete and earth. If you intend to use your 2 way radios exclusively indoors, or maybe indoors and at times outdoors, the the UHF is definitely the best choice. To explain this, let us use an example; assume you're trying to communicate with someone on the other side of the building and in between there's a metal wall which has a 3 foot opening. Basically, radio waves can't pass through metal. However, the UHF wavelength which is about 1 1/2 ft wide, will easily pass through the opening. In contrast, the VHF signal will bounce back since it's wider than the opening. This shows you that UHF is much better when it comes to navigating through smaller spaces within buildings to reach its' destination.

When it comes to power, many people tend to think that the power output increases the range, but actually the difference in the range between, say a 25W fixed VHF, and a 5W handheld, is because the fixed mounts the antenna being taller, thus can see farther. When you are trying to increase the range, increasing the height of your antenna is far more effective than increasing the power. Increased power will generally let you push through the static and such other radio traffic much better, but only within a range that's dictated by the height of the antenna.

In regards to obstacles, there are a lot of things which affect the signal strength of the radio waves. Therefore, it's important to consider the environment you intend to use your two way radios , and the actual range you need. Naturally, a football stadium will have much less obstructions as compared to a dense forest.

In conclusion, I would like to say that it is never about the radio you purchase, but the frequency, antenna and environment it will be used in. If your 2 way radio is going to be used mainly outdoors, where you will have a clear line of sight, then the VHF is the ideal choice, however, if the 2 way radio is going to be used in and around buildings, in urban areas, or in heavily wooded places, then the UHF is the best option.

Ham radio: A last resort when phone lines fail

We at this blog believe in radio communications and will never let it die, understanding the importance that it still plays, and during the worst catastrophes, will be the best form of communication. This story about 9-11 adds proof to this statement.



If disaster strikes, there is a form of communication that can still get through: a ham radio.

When 9/11 hit New York City in 2001, for instance, ham radio operators provided a connection to the outside world.

One of those people was amateur radio enthusiast Bob Kyvig, formerly of White Bear Lake, who now lives in Centerville.

“The only communication out there on 9/11 was amateur radio,” Kyvig recalled. “The telephone lines were jammed and no one was going in or out.”

On the days following that horrific attack, Kyvig assumed the role of messenger, relaying messages from Manhattan to loved ones in the area by calling or knocking on their door. His house calls would go like this: “I am Bob; I am a ham operator. I just communicated with your loved one; they are fine and doing well and they will talk to you soon.”

When White Bear Lake sailor Gerry Spiess landed in Samoa on his historic solo voyage across the Pacific Ocean in 1981, he contacted Kyvig, who connected Spiess with his wife Sally.

When Hugo’s tornado struck in 2008, he and wife Jill remained on the radio as long as they could but had to abandon the “ham shack” as the storm approached. The tornado did $30,000 damage to their home, including Kyvig’s outside antennas.

A ham since 1968, long before Facetime, email or Skype, Kyvig was 20 when he took up the hobby while serving in the Navy. He was stationed in Hawaii and had childhood buddies serving in Germany and aboard the USS Milwaukee. The three met on the radio at least once a week without fail for more than 40 years, until the death of one of the men in 2015.

That connection to people is what Kyvig most enjoys. He chats on the radio to people he’s never met around the world.

“It’s a worldwide network of people enjoying fellowship with other hams,” Kyvig said.

The radio operator answers calls for help in areas of “health and welfare,” and was on Centerville’s first CERT (citizen emergency response team), which is now inactive. He serves as a severe weather spotter too, and gains “insights” as to what is happening around the world by chatting to foreigners.

“We talk about everything from fishing, to weather and local problems,” he said. “It’s very interesting because you find out so much about people across the world. And it’s not just the personal part but handling messages for help in disasters.”

He’s listened to astronauts aboard the space station and scientists at the South Pole. He has talked to people in Russia, New Zealand and most of Europe. For a long time, he kept a conversation going with a man in Norway who lived close to some of his relatives. Wife Jill also has her ham license and enjoys talking to other women, known as YLs or young ladies, across the world. “Lord knows what they’re talking about,” Bob said. “I leave the room.”

Ham buffs do have opportunity to meet at events called “eyeball picnics.” The Kyvigs traveled to a picnic in Branson, Missouri earlier this summer to socialize with other hams and match voices with faces.

Without getting too technical, Kyvig explained that radio signals are bounced up through the ionosphere. The signal goes up and down several times before it hits the final destination and you don’t control where it hits. People who want to contact Kyvig can tune into his call number: WA0ROH, assigned by the Federal Communications Commission (FCC), which regulates interstate and international communications. The agency requires operators to keep a log of who they talk to on an electronic spreadsheet.

“We could be talking to people the FCC thinks is a bad guy,” he said. “Because we can transmit all over the world without a phone line, some use it to their own means.”

Other countries have comparable agencies.

Each country has its own beginning call letters. The United States uses W, K and N.

“The concept is simple,” he added. “We use what Mother Nature has provided: airwaves. We plug a number in for a country and anyone can answer.”

A true party line, Kyvig said 30,000 people could be listening in on a conversation.

Jill proudly pointed out that Bob earned a master’s degree from The 3905 Century Club. It’s not the typical academic degree, but a difficult achievement nonetheless. “The degree was a challenge,” he said, which explains why only 68 radio operators have received the degree since 1967.

Bob inspired her to get her license, Jill said, and together they do public service events using ham radio.

Invented in the early ’20s, ham equipment is evolving, but affordable. Newbies can do it for about $300, he said. There are antennas on his roof, but mostly they are horizontal wires stretched between a tree and the house. Generator backup is used if there’s a power outage. He also keeps a mobile 12 volt transmitter that he can use in his truck to chat while he’s driving.

At one time, working knowledge of Morse code was a requirement to get an FCC ham license, but that was dropped, so more people are getting into it, he said.

When he’s not on the radio, Kyvig enjoys making furniture and fixing TVs. He retired from a career in computer operations about five years ago.

DJs Shouldn’t Have to Live With Constant Ringing in Their Ears

When you think about DJs you don’t worry about their hearing, but this is a real issue in the music world, they seem to be slow in picking up this issue, probably because the industry can be full of bedroom DJs, that don’t consider hearing protection. As the article below says, it interferes with the mixing. This article was originally published on THUMP Canada. 

I'm waiting to get my hearing tested and I'm scared. Most of my work as a music journalist, along with my social life, has revolved around loud music for more than two decades. While I often wear cheap foam earplugs, I haven't been as consistent as I should have been, and I'm particularly worried about is the damage I've done while DJing.

I was never a famous touring DJ, but spent many years playing long shifts on a weekly basis at Toronto bars, sprinkled with occasional club and warehouse party gigs on larger sound systems. I've never worn any hearing protection in the booth, as I found earplugs interfered too much with mixing. Gradually I've noticed that I've been turning up the monitors over the course of a long night, and the ringing in my ears was taking longer and longer to fade away after each gig. A few years ago, I started to realize I was having trouble keeping up with conversations in situations where there was a lot of background noise.

Then one day that familiar ringing never stopped.

Even though hearing loss caused by loud music is a well-known reality, most working artists view it as an issue they'll deal with when they're retired, not aware of the fact that it can often impact artists at the height of their careers.

"I would go home after a gig and my ears would be ringing really badly, and then one day I noticed that they never stopped ringing anymore," says Toronto house DJ and producer Sydney Blu, who's been playing regularly since 2000. "Not long after that, I noticed that whenever I'm in a nightclub and someone talks to me in my right ear, I have to stop them and put my left ear to their mouth."

She eventually got herself fitted for custom musician earplugs, but found she could never get used to DJing while wearing them. Instead, Blu just tries to keep her monitors as quiet as possible, and turns them down completely in-between mixes. "Most of the older DJs that I know all have tinnitus. I wish I had thought about it earlier, and realized how bad it could get."

There is no way to reverse tinnitus currently, and the treatment options for hearing loss are still in their infancy. For busy DJs who are constantly touring and playing festivals around the world, many don't notice the ringing in their ears getting worse until it's too late.

"I think it's rife in the DJ field," says NYC house music veteran Roger Sanchez. "A lot of people have tinnitus and they haven't even identified it. They're just so accustomed to their ears ringing, and they think it's just because of their gig the night before. But if you're playing three or four times a week, your exposure is almost constant. Then when they step back, they realize they have tinnitus."

Sanchez has been performing for 36 years, and started to experience permanent ringing towards the end of the 90s. Like Blu, he got himself fitted for custom earplugs, and feels they've saved him from further damage. However, he admits there was a learning curve when it came to mixing while wearing hearing protection.

"In the beginning, I felt like I couldn't hear things clearly. It was like someone had put their hands over my ears. It took me a while to acclimate, but what I started noticing was that I could turn my monitors up, but it didn't sound piercing any more. I also had them put bass bins in a lot of booths, which helped compensate."

Sanchez says that it's become much more common in recent years for big name DJs to wear custom earplugs while performing. He finally got tested properly in 2010, and found there was a significant dip in upper range of his hearing around the 800hz range, but was relieved that the loss wasn't worse. The persistent ringing in his ears is still there though.

"Right now I hear the ringing, but I've just become accustomed to it. I don't notice it when I'm walking on the street, or if I'm not paying attention to it, but the second I quiet everything down, the ringing starts. It's not too loud, thank god. I think using the filters prevented it from getting to that level. I know some people who have it very loud."

Custom musician earplugs can cost more than $200, but they're one of the few options for DJs who need to be able to accurately hear the effect of their EQ tweaks and filtering. The cheap disposable earplugs you can buy at the drugstore will protect your ears the same amount, but change the sound so much that few performers use them.

"A cheap foam earplug might bring the sound down by 25db at one frequency, and 10db at another," explains Adam Rhodes, the US director of hearing protection company ACS Custom. "They muffle the sound, because it's not a true response. You can't hear anything, it takes away the enjoyment of the experience, so you just end up taking them out. When you've got the right filter though, you're not sacrificing the quality at all: you're just turning it down."

ACS works with many of the biggest names in electronic music, from Tiesto to Zedd to Deadmau5. Rhodes says that there's much more awareness of the issue now, although too often artists come to them after they've already done permanent damage. "Pretty much every week we hear someone say they wish they'd heard about this ten years ago. We hear that often," he says. "I think it's all about education. We're at a festival every weekend in the summers, trying to make it as accessible to them as possible."

Many touring musicians have switched to in-ear monitors in recent years, which block out external sounds, while amplifying what they need to hear. In the electronic music world however, they are far less common, as they require DJs to completely rethink their approach to mixing.

"In-ear monitors haven't always worked for DJs," admits Rhodes. "They like to wear the cans over their ears, so they can take them off, and do a mix with one ear covered. There are some DJs who use them though, like Deadmau5. We have one model now that have ambient microphones built in, so that they can still hear the mix. That's kind of the next level, but it's still hard to persuade DJs to use them. They're so used to wearing headphones and it's almost part of their outfit when they're performing."

One artist who has transitioned to in-ear monitors is Dutch DJ and producer Laidback Luke. He started wearing custom earplugs in the early 2000s, after becoming concerned about tinnitus and a growing lack of sensitivity to loud volume levels. Around 2008, he decided to give in-ear monitors a try and has used them ever since.

"I just wasn't getting the definition I was looking for in DJ monitors. We tried the in-ear monitoring, and I was so happy with the clarity. Even in big halls with lots of reverb, my monitoring would always stay the same," he says. "It was a revelation to me. I could keep the volume low, and still hear every little detail in the song. I couldn't hear the crowd anymore, but that just made me work harder to get applause." It wasn't until three years ago that he finally got up the courage to get his hearing tested.

Thankfully, it turns out that his early adoption of ear protection had a huge impact, and the results were completely normal. Even the constant ringing and beeping that panicked him early in his career has subsided.

My own ringing isn't nearly as bad as it was a year ago, but it sure seems loud in the complete silence of the soundproof booth in the downtown Toronto clinic where my hearing is being assessed. I struggle to hear the tones, but feel optimistic that I'm able to notice some of the very high-pitched signals they're feeding me. However, I'm also noticing that there are long pauses during where I probably should be hearing something.

"Do you work with heavy machinery?" the doctor asks me as he looks at my results, which makes my heart skip a beat. When I explain that I'm around loud music constantly, he tells me that explains what the chart is telling him, and why the highest frequency range of my hearing is still decent.

"It's not actually too bad. Your left ear has a dip at 1K, but it's still within the normal range. Your right ear has a much larger dip though, at 4K. You should really get yourself a pair of custom musician earplugs."

I leave his office feeling relief that my hearing isn't worse, but embarrassed that it's taken me this long to take it seriously. Thankfully, it's not too late for me to stop things from getting worse.
