iBetterHearing is an App to help people with hearing loss to communicate more effectively. iBetterHearing transforms your iPhone into a hearing aid, which amplifies the incoming sound, drastically improving hearing ability and correcting impaired hearing as measured by audiometry.
iBetterHearing allows you to set how it amplifies the audio frequencies of the left and right input audio signals, independently for the left and right channels, according to the result of an audiometric test performed by an audiologist using an audiometer, being able to enter the exact values from audiometric curves for the left and right hear, as reported by the audiologist.
iBetterHearing uses the state-of-art of Digital Signal Processing techniques for processing the input signal, including an innovative algorithm to adjust automatically the output level in case of input signal overload.
To use iBetterHearing, it is necessary to connect to your iPhone an headphone with a built-in microphone. A very good quality headphone is highly recommended for best results. The App runs also on iPhone 4, but an iPhone 5 or newer is highly recommended for a very much better audio quality.
