About

Decibels

Features
Read full description

Decibels is a sound level meter that remembers what you measured. Point it at the noise, press start, press stop β€” and the reading stays. Average (Leq), maximum, minimum, duration and the full level trace, saved automatically, every time. No account, no subscription, and nothing leaves your phone unless you send it. MEASURE β€’ A-weighted (dBA) or unweighted, per IEC 61672 β€’ Fast (125 ms) and Slow (1 s) time weighting β€’ LCpeak for impulses β€” alarms, slams, machinery β€’ Live level trace with a ten-second window β€’ Calibration offset for matching a reference meter KEEP β€’ Every measurement saved automatically β€’ History with the full trace of each run β€’ CSV export carrying the settings it was taken under Decibels stores your measurements on your device and nowhere else. It records no audio β€” only the level β€” and asks for no location, no account and no identifiers. A note on accuracy: a phone microphone is not a calibrated instrument. Decibels is honest about that. Use the calibration offset against a reference meter for absolute readings, and treat it as an excellent relative instrument otherwise.
