Re: AirPods causing tinnitus?

I have pretty much stopped using my AirPods (and mostly headphones connected to the iPhone) after reading that emergency alerts can cause hearing damage: https://old.reddit.com/r/apple/comments/c8s6yi/eardrums_dest... https://www.vice.com/en/article/n7naqg/apple-airpods-hearing...

Are there any software approaches that can properly modulate and equalize sound based on the various hardware factors and user preference? It seems like it should be possible.

Hearing loss is very serious. You know your body better than anyone else so don't be afraid to be its biggest advocate and protector. Nobody else will. I once had tinnitus for a week after a concert and it was one of the worst weeks of my life, it felt like it would last forever (and for some people, it does). I had pristine, "golden ears" for audio engineering and was afraid about how much I'd be able to recover. I…

> I once had tinnitus for a week after a concert

This is impossible for me. As a self proclaimed hypersensitive person with hyperacusis and misophonia, I would rather fight and claw my way out of any kind of concert or disco rather than suffering from the loud noises. Any kind of concert or disco noise means intense pain to me. Like getting stabbed in the ears.

I found a solution and peace in ear plugs, with them I can enjoy discos and anything else like normal people.

Now one question for you: I do realize the majority of humans can stand those levels of noise without earplugs and without any apparent discomfort. Do all you normies and neurotypicals simply do not have this intense pain reaction to loud noise? How the hell could you suffer through a concert so loud it gave you tinnitus without passing out from pain?

A popular YouTube channel recently recommended wearing Airpods with noise cancelling on the London underground because sounds routinely exceed 100 decibels sometimes. Unless my understanding is flawed but the mechanical / energy potential is still reaching your ear drums, cochlear and in turn the hair cells. How would equalising the sound with an opposite sound help reduce the damaged caused here?

The energy is reaching your ear in the form of sound waves. The ANC tech (when done correctly) is sending an antiphase (inverse) wave with the same amplitude but inverted phase timed exactly to the original sound wave. Effectively the two waves destructively interfere with and cancel each other out - it's not 100% but when done well is pretty effective for regular/consistent sounds

If it's not 100% for any particular reason then you are effectively adding noise and prolonging it's duration. I certainly wouldn't trust the speaker response to exactly match what the DSP is trying to produce over the wide range of audio that you could be listening to.

It may even be worse if you're here a wide spectrum of noise as some components may be canceled while others, particularly high frequencies, may be amplified.

I would always try to make passive cancellation work for my use case first, and only use active cancellation if it was absolutely required.

Yeah it can’t be stressed enough, if you go to live events, get concert earplugs and wear them religiously. You hear the music better anyway.

It’s been sad to see friends fail to heed this advice. You don’t want to be that person who needs hearing aids at age 50 due to something you could have prevented with a little forethought.

Etymotic are great and were my standby for years. Recently upgraded to Earasers on the recommendation of a musician friend and I am very happy with them, frequently forget they are even there.

This is hardly exclusive to apple hardware. Putting small speakers on your ears isn't a very good idea in the first place. Let alone using them to block external sounds. You can get much, much worse tinnitus from not paying attention to the volume of your headphones.

I wonder if it's the noise cancellation causing problems. I definitely hear a high-pitched noise from the noise cancellation feature and rarely use it at all specifically because of that, except very infrequently like on planes. Maybe the high frequency noise is damaging the ear drums at high frequencies? But I can definitely say I do not have tinnitus despite wearing AirPod Maxes quite often.

Ummmm. ANC attenuates certain frequencies and fails to attenuate other frequencies. Which you would end up hearing anyway if you weren’t wearing the headphones. So effectively the sound power reaching your ears didn’t change for those frequencies. I have worked on ANC systems in automotive applications.

Your ears are a complex system. Just like when your eyes think it's darker, your pupils dilate, your ears have a similar method of controlling how much sound gets to the sensitive bits.

It's possible that ANC convinces your ear to open up a bit more, leading to damage in the frequencies that it doesn't attenuate.

I have the feeling that this is related to noise cancelling in general. I have some Sennheiser over-ear headphones with ANC and initially I had the same feeling. After using them I notice that my ringing (I already had tinnitus) got worse. It wears off after half a day or more, but it's slowly getting worse overall.

My theory is that it's not possible to create an exact counterwave, so occasionally the delayed ANC "counterwave" will add up to the external sound, increasing it. Maybe this happens is very short bursts or mostly at frequencies which are too high to be really noticeable.
