## What is dB Decibel Meter & Sound Test?

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.
