I'm a drummer. Fortunately before I destroyed my hearing my dad forced me to wear ear defenders.

since then it's been a habit. These look nice and all, but basically all you really need are ear plugs.

comfy, snug and 32db (depending on version) of attenuation. That means that you can go to a loud gigs (95db) without the risk of tinitus.

same goes for bars. Loud noises are draining, have your hearing shattered by someone shouting in your ears is a pain.

Yes, if you choose the colourful ones its obvious. there are natural colours.

Bose makes a lot of song and dance about how you can adjust for noise, your ears do that already. The advantage of normal ear plugs is that you still retain some of the dimensionality that earphones loose.

Sadly I've had a child, and all that shrill screaming has basically killed off 10db of sensitivity of my hearing. but I'm 10db up form most of my musician friends

Wow, this address a major problem I have. I have decent hearing, but when I'm in a noisy environment like a bar, I can hear but can't understand what other people are saying. It's why I don't like going to bars/pubs with live performances or ambient music. People think I'm bored or brooding because I'm not talking to anyone, but I just can't understand anything anyone says, so I can't participate in a conversation.

Actually just getting some earplugs helps this. Will filter your noise and make it really easy to have a conversation at normal level with someone near you. Use this myself for sports events, sometimes lounges, and of course flights. They cost way less than these headphones and work just as well to quell the problem you have. Or if you don't want to use earplugs, just plug your ears when someone is talking to you. Sa…

I've recently started carrying earplugs on my keychain for basically this reason, everything just sounds much better. The only tricky thing is remembering to speak loudly enough so that everyone else can hear me.

I actually use my normal noice cancelling BOSE headphones for this sometimes.

If one presses the passthrogh button it has a somewhat enhancing effect.

I have a similar problem in loud spaces.

For me, the results were that I have hearing ability on-par with a ~5 year old, and they only see adults like me every 18 months or so. I've got a printoff of the chart around…

I went to an audiologist a few years back because I could hear certain things that would drive me up the wall. I thought it might be tinnitus or something like that- I ride motorcycles, am on the water in boats, use power tools, etc. Turns out I have exceptional hearing as well, and much better high frequency responses than an average 30 year old.

What you are most likely hearing are switched-mode power supplies, the cheaper the nosier.

https://en.wikipedia.org/wiki/Switched-mode_power_supply

"The operating frequency of an unloaded SMPS is sometimes in the audible human range, and may sound subjectively quite loud for people whose hearing is very sensitive to the relevant frequency range."

Even analog power supplies will generate a 50/60hz hum (depending on what the power-lines are providing)

> Would it be possible to generate anti phase wave out of these things to cancel out tinnitus? No. Tinnitus is not caused by a real sound. It occurs somewhere after the phase-erasing Fourier transform performed by the physical structure of the ear. If it were caused by a real sound, or the brain added sounds in the time space (rather than the frequency space), it would work. But neurons are not fast enough to handle…

But neurons are not fast enough to handle time-domain sound processing, so they offload Fourier transformation to the ear and then work with the (presumably phaseless) frequency-domain representation. Then how is it that you can play one frequency into one ear and a slightly different frequency in the other ear, and the brain will register the beat frequency?

Keep in mind that the binaural beats community spouts a lot of BS.

Only for the lowest frequencies (say, under 100 Hz) are there reliable traveling waves to even measure in the brain. Due to the firing refactory period where a neuron resets its membrane potential, most neurons have a max firing rate in the range of 250-300 Hz, so it's not possible for difference tones to explain any binaural beats above those frequencies.

Even for lower frequencies in the range of delta-gamma waves, it seems deeply unlikely that difference tones are the explanation, because the neurons encoding for frequency are separated spatially, so it's not as if two traveling waves reach the same neuron, subtract out, and result in the difference frequency.

However the brain produces the beat frequency, it's nothing like the way signals subtract in other media.

Same issue, although exacerbated by a misspent youth near noise sources like teletypes and machine rooms. Certain high frequencies in my hearing spectrum were damaged which, as an audiologist demonstrated for me once, means I can't hear some allophones, especially from people with high voices (children, women). When its nominally quiet, my brain can fill in what those allophones would have been and I "hear" them normally, but when there is wide frequency noise in that spectrum the missing allophones cause the phonemes to become impossible to decipher. She had this tool that would play back words and could remove frequencies with a notch filter and replace the missing sound with either silence (still understandable) or noise (not understandable). Tuning a hearing aid to boost those weak areas works well for me with the exception that hearing aids don't benefit from the brains ability to focus on sounds in particular directions so they enhance the spectrum areas from all around rather than just where I'm looking.
