dB Decibel Meter & Sound Test

Noise Log, Report & Analyzer

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

Noise keeping you up? See the level live for free, then keep a timestamped record and share a clear PDF report with Sonark Pro. No account, no ads. 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. SONARK PRO Weekly, yearly or a one-time lifetime purchase. Where an introductory free trial is offered, the paywall shows it and the renewal price before you start.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

What's new in 1.1 • Spectrum analyzer (Sonark Pro): your FFT size, window function and averaging settings now apply to the live spectrum, with an optional peak-hold trace. • Noise dose estimates always use A-weighted sound levels, regardless of the meter’s selected weighting. • Saved sessions and PDF reports label the equivalent continuous sound level (Leq) according to frequency weighting, including LAeq, LCeq and LZeq. • A clearer meter layout on smaller screens and a steadier noise-zone label. • Free-trial details appear only when you are eligible. • Simpler onboarding and subscription screens.
