PETRALEX

If you have a hearing impairment, you may be looking for an application that allows you to customize your computer's audio output, so that it compensates for your hearing loss.

PETRALEX is a useful tool, designed to amplify the sound being played by various applications, depending on various user profiles. It allows you to take a hearing test, with the purpose of determining your level and type of hearing loss.

After launching the application, you can create your first profile and, to do this, you are required to take a hearing test. The program plays a series of sounds, on various frequencies, to determine which you them you cannot hear well.

This is a very useful function, as hearing loss rarely occurs across the entire audible spectrum. More often than not, people have trouble, for example, hearing only high or low-frequency sounds. The test is performed for each ear separately, to take into account different degrees of hearing impairment.

To further customize your profiles, you can modify various audio parameters. To begin with, it is possible to change the compression level, which determines how much the volume of quiet sounds is increased.

You can select the amplification method to be used. Various profiles provide different forms of audio enhancement, depending on the type of hearing loss you are suffering from. You can choose between Petralex, NAL, Berger and Pago.

Moreover, you can manually adjust the system volume and the amount of amplification from the program's main window.

PETRALEX is very easy-to-use, as it features a simple interface, designed to be accessible even for users who have limited experience with computers.

However, it should be noted that the application's interface does not appear to be fully translated into English, which could prevent some users from using all of the program's functions.

PETRALEX is an intuitive tool that can help people suffering from hearing loss customize the audio experience provided by their computers, to compensate for this particular impairment.
