Petralex Hearing Amplifier

How does Petralex work?

Petralex amplifies sounds picked up by your phone's microphone and delivers them through headphones after processing them according to your personal hearing profile.

Is Petralex a substitute for a professional hearing aid?

Petralex can assist individuals with mild to moderate hearing loss but is not a replacement for a professionally fitted hearing aid. Consult an audiologist for comprehensive hearing care.

Can I use Petralex without headphones?

While Petralex can be used without headphones, the audio quality and effectiveness of the amplification will be significantly reduced. Headphones provide a more direct and controlled audio experience.

How do I create my personalized hearing profile?

The app includes a built-in hearing test that allows you to create a personalized audiogram. Follow the on-screen instructions and adjust the sound levels until you can barely hear them.
