Woalá app for iPhone and iPad

Woalá is a hearing aid simulator. The sound is captured by the microphone, processed and transmitted to the earphones. You can interact with each part of the system, adjusting parameters for each step of audio processing. The effects are applied live to the ambient sound. Woalá does more than just increasing volume. With it, you can experience different patterns of sound correction which are similar to the ones present in current hearing aids. Characteristics:

• Live sound processing (requires earphones);
• Automatic gain control (AGC);
• Band limiting (low and high frequency cut);
• Noise reduction;
• Graphic equalizer, for hearing loss compensation;
• Use good earphones.

Bear in mind that this is merely a simulation, and does not replace treatment of any kind. Check you hearing frequently with qualified professionals. Visit www.woala-app.com for more information.
