Noise Meter: Decibel dB

Check whether footsteps from the flat upstairs, a neighbour's music, building work or traffic noise goes over the limit. Answer three quick questions and each measurement is judged minute by minute against the right reference: Korea's apartment impact-noise rule or the WHO community-noise guideline. Whether it went over is always free.

Check sound levels as soon as you open the app. Noise Meter shows a live dB reading, analogue gauge, recent chart, minimum, average, maximum, peak and Leq.

Phone microphones vary by device and environment. Measurements are reference estimates and do not replace a certified meter or legal evidence.
