Sound Monitoring - A simple solution from James
Above are pictures of two mobile phones showing sound metering applications - one on the iPhone 2 and the other under Android on the Samsung Galaxy Tab. This is in answer to the Tescowatch blog question about these devices.
The main barriers to professional acceptance is frequency response and calibration. Mobile phone microphones are probably designed around human speech frequencies, and drft in any electronic device means frequent calibration is required for professional results. The Android app claims to have been calibrated on the Galaxy Tab but I don't know how reliable that is.
Still, they are free, easy to operate and should indicate any gross violation.
