Technology Benefits

Sound quality

High quality sound

Now it is possible to use sampling rate of 44,1 kHz, which is much higher than used regular hearing aids. Higher sampling rate makes pass-band wider – so you can hear broader sound range with the app.

Auto test

App auto adjusting

Petralex will be tuned for your hearing within 3 minutes. It`s the first hearing aid that tunes itself automatically without special study room, equipment and qualified audiologist`s help.

Many profiles
