A clear, immediate sound-level check for everyday listening, studios and live environments.
Db is a simple sound-level meter designed for quick, clear listening checks.
See the current level, session maximum and a highly responsive waveform at a glance. Choose A, C or Z frequency weighting, switch between Fast and Slow response, and use the visual threshold guidance to recognise when hearing protection may be appropriate.
Db includes a persistent calibration trim for comparison with a trusted reference meter. It requires no account, contains no advertising and keeps microphone analysis on your iPhone. Audio is analysed live and is never recorded, stored or transmitted.
Db is intended as a practical listening guide. It is not a certified occupational, medical or regulatory measurement instrument.
