dB Decibel Meter & Sound Test

Noise Monitor & SPL Reader

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

One measurement a day, free — no sign-up, no trial wall. Pro removes the limit and turns any session into a timestamped PDF. Open it and you are already measuring. No sign-up, no trial wall, no form standing between you and the number you came for. Your first measurement each day is free, with nothing held back: every frequency weighting, every response time, and the full statistics — LAeq, true peak, and the L10/L50/L90 percentiles almost nobody else shows you. Sonark Pro lifts the daily limit and unlocks the analyzer, dose tracking and report export. MEASURE PROPERLY • A, B, C, Z and ITU-R 468 frequency weighting • Fast, Slow and Impulse response, implemented to the values IEC 61672-1 actually specifies: 125 ms, 1 second, and 35 ms rise with 1.5 s decay • Live level, LAeq, Lmin, Lmax and an unweighted true peak • L10, L50 and L90 — the percentile figures noise limits are usually written around, and which almost nobody else shows you • A reference scale that tells you what 70 dB actually sounds like PROVE IT HAPPENED Anyone documenting a noise problem hits the same wall: screenshots are not evidence. Sonark turns a measurement into a proper report — a timestamped PDF with the place, the level chart, LAeq, Lmax and the percentiles, plus a statement of what instrument took the reading and in what state. Log a neighbour, a building site or a workplace over two weeks and combine it all into one document. FOR PEOPLE WHO WORK WITH SOUND • Spectrum analyzer with FFT up to 16,384 points and selectable windows • Spectrogram, and 1/1 and 1/3 octave RTA on IEC 61260 band centres • NIOSH and OSHA dosimetry, kept separate and labelled with their parameters • External microphone support with saved calibration profiles • Import a voice memo or a video and run the whole analysis over it offline ALSO IN THE BOX Apple Watch app that measures on its own. A widget that shows today's peak and exposure. A Live Activity for a running session. Optional Health integration. On-device sound recognition that labels an overnight session by what actually made the noise — snoring, traffic, a door — with nothing leaving your phone. BEING STRAIGHT WITH YOU An iPhone microphone cannot hear below about 30 dB. A silent room reading 30 is the floor of the instrument, not a fault, and we say so in the app instead of letting you think it is broken. Sonark implements the characteristics of IEC 61672-1 but is not a certified Class 1 or Class 2 meter — no phone app is. SONARK PRO Pro lifts the one-a-day limit and adds PDF report export, unlimited saved measurements, the full analyzer, NIOSH and OSHA dose tracking, sound recognition, file import and data export. The 3-day free trial is on the weekly plan, and the paywall tells you what weekly comes to over a year before you start.
