How loud is it here, really.
A sound level meter that tells you what it knows: A, C or Z weighting to IEC 61672, Fast and Slow, LAeq, peaks, L10 and L90, and how long you can stay before your daily exposure reaches the 85 dB(A) upper action value, with a plain note while you are still under the 80 dB(A) lower one. Below 30 dB and above 105 dB a phone microphone cannot measure honestly, so the app shows < 30 or > 105 instead of a number. It is a first scan, not a class 1 or class 2 sound level meter. Calibrate once against a real meter; until then every screen says the reading is uncalibrated.
Free
- Every value, the timeline per second and your history
- Exposure in hours against the upper action value of 85 dB(A)
- Calibration against a reference meter, input choice
- Your first shareable PDF report
Pro · EUR 5.99 one time
For when the number has to leave your phone: a report you can hand to a client, a landlord, a safety officer or the council, with your name on it, as a first scan and not a certified measurement.
- Unlimited reports
- The share of the session above the 80 and 85 dB(A) action values, not just the average
- Octave-band spectrum, 31.5 Hz to 8 kHz, on screen and in the PDF
- Side-by-side compares, your logo on the report, CSV or JSON export
Measuring is free and complete, so you always see every value. Pro is a one-time purchase through Google Play, no subscription, and it unlocks the report and the tools, never your own data. You buy it inside the app, on the report screen, and it comes back with the same Google account on a new phone.
