PETRALEX is a powerful, easy-to-use hearing aid app developed by hearing experts.

As a portable hearing aid, it is capable of changing the sound volume, balance, and tone of your hearing. You can also control the sound with simple button presses, or with gestures on your smartphone.

In addition, this app provides a variety of tools to measure the sound of your ears, such as volume, tones, distortion, noise, frequency, and more.

How does the Petralex app work?

The Petralex app uses technology based on a combination of artificial intelligence and digital signal processing (DSP).

PETRALEX adjusts to your hearing automatically. It recognizes the level of the sound you are listening to, and it then adjusts the volume level of the sound.
