The iPhone Awareness strays away from the traditional noise cancellation technology of headphones. Many times when we wear headphones around town, we don’t hear when people are calling to us, warning us of impending danger. That is until the Awareness iPhone App came along.
It runs in the background and samples the general ambient noise using your iPhone’s (or headphone) mic. This is the threshold. Any outside noise that isn’t as loud as the sample won’t be played through your headphones while listening to your music. But if suddenly a bus comes down the street, the app will allow the loud noise of the bus to penetrate into your ears. In other words, the Awareness app makes you aware of noises that you wouldn’t otherwise hear with your standard or noise canceling headphones.
The Awareness iPhone App should provide you with a more isolated listening experience. So if you’re riding the train and someone is yelling in your direction, you’ll be able to hear that person but not the rumble and squeal of the locomotive. The technology is based on decibel level threshold and not frequencies.
