Following a stream of incidents where teenagers or cyclists have been hit by a car or truck because they were listening to music with headphones on, London based company Essency has released Awareness! The Headphone App. The philosophy behind the app is to allow users to listen to music, whilst remaining street safe and street smart. When listening to music (at any desired volume) a user will be able to hear important sounds, like a siren, shout or directed conversation. The application utilizes the inbuilt microphone on the iPhone and iPod Touch to record outside sounds and by recognizing the street level sound it will then “bleed” all louder noises through the headphones.
