Brilliant!
As a hearing aid user since 1981 I am pleased to recommend Petralex
Being able to create profiles is marvellous.
Background noise can be eliminated and the sensitivity is incredible.

4. Worldwide sales of hearing aids is only 13 mln. for $9,75 billion annually
while the market is constantly growing by 11%.
In the US, 48 million hearing-impaired people are in need of affordable equipment
and devices.
Auditory prosthesis for both ears in the US costs $4600*.
We offer to restore hearing for $99.
*An average price for a auditory prosthesis is $2300 ranging from $685-$2800 per auditory prosthesis
In China, 220 million people have hearing problems.
Auditory prosthesis in China costs 10 000 yuan*.
We offer to restore hearing for 599 yuan.
*One 6 channel hearing aid in China costs from 3000-7000 yuan
Best hearing aid app I know
Very user friendly and versatile, easy to adjust to your hearing loss.
Great complement for hearing aid!!!

FOR PEOPLE WITH HEARING IMPAIRS
Absolutely wonderful and outstanding app! It has more settings than any other app
I tried + hearing test + it has NO DELAY that other apps does. I finally can hear teacher in class,
I can study now and I couldn't be happier! I recommending to people who left a bed reviews,
to go and buy real hearing aid for hundreds of dollars, and try it. I have it and it much worse
than this app because doesn't have all that features as amplifing some particular frequencies.
This app is free, and I don't know how you dare to complain. Best wishes to creator!
I'm a software developer and I know what it's worth to create an app. They don't.
Thank you so much!
P.S.: for those who saying that they can't do nothing but hearing test -64
you just need to press on profile and it will begin to work. Jesus Christ, people!

PROVIDE WITH THE NEEDED TIPS TO WORK WITH THE APPLICATION
Interaction with international and national telemedicine
platforms
The user can avoid visiting
the audiologist, significantly saving time and money
Life Saving App
Truth to be told this app saved my life. I have a moderate hearing loss
in my right ear and it happened suddenly year ago and I’m having
hard time to focus on human speeches and this helps me to listen.
Without this I would’ve been jobless! Thank you guys!

12. Details about Dectone amplification rationales
Dectone is more complex approach to amplification. It is orient-
ed to correct recruitment based on above-threshold audiome-
try
The idea is to estimate the equal loudness curve for user hear-
ing in order to make correction of the recruitment more effec-
tively
This is done simultaneously for both ears in order to estimate
their relative sensitivity and provide balanced binaural correc-
tion

13. Potential for reducing Android processing-time delay
Android becomes a real-time operating system based on changes since the audio
part android 7 and 8, as well as the introduction of API AAudio
Google tightened requirements for manufacturers, regarding the audio part;
Was implemented API AAudio designed for high-performance audio applications
that require low latency (MUST have the continuous round-trip audio latency - 20
ms or less);
Announcement of work on the unification of the type-c connector, with the aim of
creating a new USB substandards for real-time use

15. ECOSYSTEM
We plan to provide software developers with SDK for
audio personalizing on the user's side. Our SDK essen-
tially important for video hosting, stream-music services
and video and voice messengers. A separate audio
plugin is provided for browsers. Integration of third-par-
ty applications into a single ecosystem occurs through
hearing testing in our services - Petralex, Dectone, Hear-
ing test Plus. According to our estimation, the conver-
sion of users using the sound personalization functional-
ity to users of the paid application Dectone is 1%.
