BioAid is a research hearing aid designed by hearing scientists. It works by processing sound from the microphone and then playing it back over headphones in real time. The processing is designed to enhance sound clarity and regulate the loudness of ambient noise. BioAid is unique by virtue of using new audio processing techniques inspired by recent scientific developments in our understanding of the biology of hearing.
To start using BioAid, you don't need a hearing test. Instead, you are invited to try a wide range of different settings to discover which one suits you best. Choose between different settings appropriate to common types of hearing impairment. You also have control of the overall sound level and can vary the rejection level of background sounds.
BioAid is free. Download it and begin exploring its potential immediately!

BioAid can be used with any kind of headphones or earpieces, but you will need to use insertable earbuds that block out external sounds to fully benefit from the 'loudness control' features.

Not a bad bit of kittried this for the first time today. as i am


Tried this app for the first time just now... still experimenting with it, good sound through jack plug headphones.... but at the moment i am trying it with a pair of wireless headphones. bit laggy and echo. but with some fine tuning will hopefully be ok. nice app BioAid. hopefully some useful addition to come. if the bluetooth could be improved i would definitely buy this. thank you

Not just an Amp! :-D


Having tested a few other apps, this one surpasses the rest. It provides a simple user friendly way of selecting the frequencies you need amplifying, other hearing aids just make everything louder which makes them uncomfortable most of the time. This allowed me to select the best frequency, and picks out the detail in the sound that is usually hard to hear for me, I plugged in my hands free kit with earphones and mike in the cord, and it just looks like I'm wearing earphones, brilliant!!

I'd been using a different hearing aid app, which was okay, but hard to get enough boost without it sounding tinny. BioAid is far better - good amplification, and once you've found the best setting the sound quality is great. My only request is that later versions remember your preferences, which I don't think this one does (that's not really a problem though). Great app!
