#2Do you hear the constant "i"?
Why every ppl is ears tested in societies? :D

#3Now this is a real hacker post! Kudos to the author.
I have some mild tinnitus and listen to hours of audiobooks a day. I could see this being a great add-on to apps like Audible or Bound.

#4I’m surprised that 30 decibels is considered mild hearing loss. Every 6 decibels is roughly a halving of sound pressure so if you have 30 decibels of loss you’re hearing 1/32 of the sound that a person without any hearing loss would hear. That’s not mild!
This is a very cool project, I wonder if modern hearing aids work in a similar way- by tuning their response to the person wearing them?

#5I have age-related hearing loss: bass frequencies are ok, but high frequencies drop off. When I first got hearing aids, I thought that what they did was boost the frequencies as necessary as (I think) described by this author. But hearing is not a linear system. The hearing aids do boost the frequencies where I am deficient, but by an amount much smaller than the difference between my audiogram and normal. I think that the objective of hearing aids (for mild hearing loss like mine) is to boost frequencies just enough for them to be audible to my brain, at which stage the non-linear system in my brain processes the signals to sound normal.
I have not confirmed this speculation with an audiologist, so I would love comments on this from someone who works on hearing-aid software.

#6You could make an analog version of this fairly easily too, with a handful of resistors and capacitors to form a high pass network and a signal booster to get the 60db of gain you need.

I have a basic model provided free by the (UK) NHS. It is tuned to my audiogram by my NHS audiologist.
More sophisticated models do a lot of tailoring, both to the person and to the environment. By way of example:

#8Just wowww
Re: Experimenting on My Hearing Loss
#9Objectively, my hearing is just fine. I can hear frequency sweeps and tones perfectly well, but all my life I've been unable to pick out words in conversation if there's even moderate background noise. "What?" is likely my most commonly uttered phrase.
This leads to people constantly telling me to get my "hearing checked", when it's not the ability to hear tones that's the problem.
Rather irritating explaining this to people.

I recently noticed that my high-frequency hearing was going (40-yr-old man). My GF (works in a hospital) brought home a digital thermometer that beeps when it's finished a reading. My GF can hear the beeps clearly, but I cannot. She has to tell me when the thermometer is ready to be read. Perhaps I should go to an audiologist to get a proper exam.
