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.


  1. Are there also requirements in terms of operator training to obtain a meaningful result?

    As a member of the Considerate Constructors Scheme (supposedly), surely the pipeline operators have a responsibility to ensure they are complying with the planning constraint, and so should demonstrate effective monitoring of the pipeling noise. What are EDDC doing to ensure compliance.

  2. Haha what a brilliant app from Apple. When I had to choose a smartphone, I wasn't familiar with the benefits of each device and I chose BB over Iphone. What a mistake. I have no fun apps in my BB whatsoever.
