PRIVACY BY DESIGN
SoundMeter analyses microphone amplitude in real time and never records or saves any audio. Nothing you say is stored or transmitted.
IMPORTANT
Readings are estimates. Phone microphones vary widely between models and are not calibrated instruments, so this app is not a substitute for a certified sound level meter.
Useful for checking a noisy office, a nursery, a workshop or your neighbourhood.
