Digits in Noise Test app for iPhone and iPad

Digits in Noise Test is a program that can be used to measure your ability to recognize digits (or speech) in the presence of background noise. The listeners are presented with a series of digits (generally 3 digits) with noise and must immediately repeat them back. If the answer is correct, a different list will be presented with reduced signal-to-noise ratio. The signal-to-noise ratio a person can identify digits on 50% of all trials is that persons speech (or digit) recognition threshold. With the highlighted feedback, the program can also be a useful tool to improve the listeners ability to understand digits (and/or speech) in the presence of background noise.
