Researchers at University of Essex have developed a new app that can turn your iPhone into a hearing aid.
The app, known as BioAid, is free to download and works with iPhone, iPod touch and iPad.
There are six fixed settings that the user can select to address their particular type of hearing loss with each of the settings four fine-tuning sub-settings which allows the user to target the specific frequencies that they have difficulty hearing.
The app works by increasing the audio levels of only low sounds while turning down the audio levels of loud sounds, similar to what a human ear does. "We are very excited about the potential of BioAid which could genuinely change lives. People with hearing impairment very often withdraw from public life. Even if they have a hearing aid, the technology is not sophisticated enough to offer a tailor-made solution to their impairment and in many cases people simply stop using them", lead researcher Professor Ray Meddis said.
