dB. Noise Monitor is a professional sound meter for your iPhone, iPad and/or iPod. dB. Noise Monitor can measure environmental noises in decibels.
dB. Noise Monitor uses your iDevices microphone to measure levels of noise or sound pressure levels and displays measured data in dB (decibels) with reference to generally known noise (provided by American Academy of Audiology).
Microphones in iDevices are made to record human voice, therefore the maximum noise is limited and very loud sounds cannot be recognized (in most cases above 100dB). dB. Noise Monitor is calibrated to be accurate in +/-2.5 dB range of actual noise level and is probably by far the most accurate sound meter in the AppStore. We have adjusted dB. Noise Monitor with the use of professional sound meter used by sound engineers and made required adjustments for many iDevices.
