SoundCurtain for iPhone

07.05.2009

For headphones, the standard iPhone headset/microphone kit worked well. The application uses the headset-embedded microphone to monitor ambient noise--if you plug in headphones lacking a microphone, monitoring switches to the built-in mic. For the hard-core, switching to passive noise reduction headphones--employing a earbud inserted within the ear canal--adds a physical seal against noise that effectively complemented the aural barrier provided by SoundCurtain.
