Questions and Answers

1. What can I use Petralex for?

Let’s say, you want to watch TV with your friends or relatives. Adjust your TV set to the comfortable volume, then launch the application, add a new profile and conduct the test in the room with TV on. We recommend to direct the microphone of the device to the source of sound (TV) when using Petralex. Now when you turn this profile on you can watch TV with your friends with the volume that is comfortable for everyone!

2. Can I use the application in the cinema?

Yes, you can use it while visiting cinema, theatre or opera. We recommend you to create a corresponding profile and switch it on when watching. You should also switch the used microphone into the mode "Microphone in the phone (tablet)" and hold the device in your hand or put it on some surface in the direction of the sound source.

3. I have second degree hearing loss, can I use Petralex instead of hearing aid?

You can use the application to improve the intelligibility of speech for different conditions of acoustic environment, but the application itself is not a hearing aid. The application was tested for patients suffering from sensorineural hearing loss with hearing disorder of first and second degrees. The results were successful, but this version of the application is not certified to be called a medical hearing aid. If you decide to try this application (it is free), please leave your review in the corresponding section and describe your experience and propositions.

4. I cannot hear quiet sounds well but if I switch Petralex on, won't loud sounds be too loud for my hearing?

Petralex uses complex algorithms of sound processing with non-linear amplification. This means that you will hear quiet sounds and speech better while loud sounds remain on the same level. The sound in the device is equalized in such a way that quiet sounds are amplified in accordance with set parameters while loud ones remain on the same level.

5. Sometimes the noise becomes too annoying, why is that?

When the volume of the phone is set at maximum and the function of Acoustic feedback suppression is on, the white noise is amplified too much. We recommend you to turn the volume down a bit and lower the sensitivity of your microphone.

6. What do buttons NAL, Berger, Pogo and Petralex in the Amplification section mean?

NAL, Berger, Pogo and Petralex activate different amplification formulas. NAL, Berger, Pogo are the most wide-spread amplification formulas in the world, Petralex is a unique formula created for our application.
