This fascinating iPhone app called EarTrumpet was developed in collaboration with the Department of Otolaryngology Head and Neck Surgery at University of California Irvine. The app claims to convert your iPhone/iPod into a hearing aid of sorts (hearing enhancer app is the term they use) via headphones with a built-in microphone (the ear buds that come with the iPhone work just fine). In essence, the microphone will pick up the surrounding sound and the app will instantly amplify the sound and play it into the headphones. The degree of amplification is customizable via the app.
Hearing testing is also available.
As per the manufacturer website, the EarTrumpet features include
• use of the built-in microphone on the supplied iPhone ear buds
• allows the user to select which frequencies to boost.
• choose the left or right ear to amplify
• store custom profiles once balance and equalization settings have been selected
You can download the app here which sells for $1.99 (much less than traditional hearing aids which go for $1000 and higher). Watch the tutorial of how the app works below.
On a further note, EarTrumpet was created by Allen Foulad, a medical student.
