Whether its going to a rock concert or blasting country music in the car with the windows rolled down, everyone loves to enjoy the world through their ears. This special gift can be damaged, so we developed an app to help protect your ears.
What it does
The app monitors the decibel value of the iOS microphone and informs you how much longer you can safely be in a loud environment.
How I built it
We used Swift 2.0 to build this app with iOS 9. The permissible exposure limit (PEL) is calculated using the United States Department of Labor time-weighted average (TWA) formula for calculating the decibel average (dBA).
