Volume Decibel Meter provides a way to measure environmental sound levels, showing the approximate dB level (decibel level).

It also provides an approximate "decibel guide" at the bottom of the application interface, so that you know what sound levels correspond to a health hazard.

Please note that microphone sensitivities vary a lot, so the reading you get should be considered approximate (take it with a grain of salt!)

This decibel meter also gives you a convenient start/stop button, and records the minimum and maximum decibel reading. You simply tap on those readings to reset the minimum and maximum back to 0.

NOTICE: Version 1.0.2 has now been released! It has been re-calibrated for the iPhone mic. The old version (v1.0) was calibrated about 30 dB too high.
