Hush: Decibel & Noise Meter

Hush is an iPhone decibel meter for noise you need to show someone. The live meter is free and shows live dBA plus LAeq, Lmax, LCpeak and L90, with an octave-band analyser. Hush Pro turns readings into a record: each recording saves the level with a photo, GPS place and time; a live camera puts dB, place and time onto photos and video; dossiers group recordings per address, venue or site on a map; and PDF or CSV reports state the method and limits. Sound is analysed on device, saving audio is optional, and no account is needed. Readings are indicative; Hush is not a certified sound level meter.
