Noise Radar - dB Sound Meter

Noise Radar (dB Sound Meter)

A military-radar styled CRT console that measures ambient noise in real time. Audio is analyzed on your device to show an estimated decibel (dB) level and a noise grade, and loud events over 85dB hit the scope as radar blips with an instant alert.
