Hearing Tool

iPhone / Utilitaires

This app can help people who are hard of hearing. Included in the app are three module.

The first module is a frequency-based hearing test. The older people get, the less high frequencies they can hear. This test uses this information to determine how ”old“ your ears are. This age should be similar to your own age.

The second module uses various audio effects to optimize recorded audio to make voices more understandable. For people who are hard of hearing, understanding voices can sometimes be difficult when there are lots of noises in the background. This utility tries to optimize audio by reducing frequencies which often contain background sounds. The audio will also be played back more loudly.

The third module can help someone who is hard of hearing differentiate between multiple sounds. In many situations, you need to differentiate between two or more sounds, which can be a problem if you can’t hear those sounds. On this module, you can teach the app to differentiate between multiple sounds. Once you added two or more sounds, you can press ”Recognize Sound“ to classify a recording. When the user lets the app recognize another sound, the classification of the new sound gets compared to all existing classifications. If two classifications match, the result gets presented to the user. When adding a sound, you don’t train the model directly, which is more efficient and faster.
