dB Decibel Meter & Sound Test

Noise bothering you at home or at work? Sonark shows you how loud it really is, keeps a record you can look back on, and turns it into a report you can share. The live meter is free and unlimited: no account, no ads. Sonark Pro adds recording and saved sessions, the analyzer, noise dose, sound labeling, file import and report export. MEASURE WITH CARE • A, B, C and Z frequency weighting • Fast (125 ms) and Slow (1 s) time weighting, plus Impulse (35 ms rise, 1.5 s decay) • Live level, Leq, Lmin, Lmax and peak level • L10, L50 and L90 percentile levels to summarize changing noise • Everyday sound examples to put each reading in context KEEP A RECORD (PRO) A screenshot shows a moment; a report brings your recorded measurements together. Sonark turns a session into a timestamped PDF with the level chart, Leq, Lmax and the percentiles, the measurement conditions and calibration state, and the place when you choose to add it. Log a neighbor, a building site or a workplace over days or weeks and combine the sessions into one document. FOR PEOPLE WHO WORK WITH SOUND (PRO) • Spectrum analyzer with FFT up to 16,384 points, selectable windows, averaging and peak hold • Spectrogram, and 1/1 and 1/3 octave RTA on IEC 61260 band centers • NIOSH and OSHA noise dose estimates on A-weighted levels, kept separate and labeled • External microphone calibration, with multiple saved profiles • Import a voice memo, a recording or a video and measure its levels, statistics and sounds offline (levels are relative unless you enter a known reference offset) ALSO IN THE BOX A free Apple Watch app that measures on its own. With Pro: a widget summarizing today's saved measurements and estimated dose, a Live Activity while you record, optional Apple Health logging of saved sessions, and on-device sound labeling that marks an overnight session with the likely source of detected sounds — snoring, traffic, a door — without sending audio anywhere. BEING STRAIGHT WITH YOU Sonark displays a minimum of 30 dB; readings depend on the microphone, the device and calibration. Sonark implements A, C and Z frequency weighting and Fast and Slow time weighting as described in IEC 61672-1, but it is not a certified Class 1 or Class 2 sound level meter, and its dose figures are estimates, not a medical assessment.
