App turns iPhone into a hearing aid

 BioAid uses the microphone and headphone functions of smartphones to amplify the sounds around deaf users in real-time.

Many of those with hearing problems have consigned themselves to wearing a hearing aid – which can often be cumbersome and expensive. The SCS1000 smart watch has already made steps towards helping deaf people remain aware of their surroundings, and now UK-based project BioAid is harnessing the power of smartphones to provide an easier and cheaper way to amplify the sounds around them.

The concept is quite a simple one: the app takes in sounds from the user’s surroundings using the iPhone’s built-in microphone, amplifies it using algorithms tailored to the user, and plays it back through either the loudspeaker or headphones in real-time. Users can configure the app using one of six settings to best suit their condition, which can then be fine tuned even further.
