Comments on Sound meter : SPL & dB meter for Android
★★★★★JC Carey· Jul 23, 2026
Aces! I like this app. It's accurate. It has a description of items in the sound range it was registering. For example: I'm in a quiet room with grandfather clock ticking and if you listen carefully you can hear the low roar of the city in the background. The app is registering clock ticking, quiet room and a bit above. Excellent calibration. Speaking of calibration you can adjust it too. Someone took some time with this app. Thank you

Works amazingly well! I am using it to troubleshoot erroneous hvac blower motor rpm and static pressure readings. The do meter confirms a failed ECM at the blower motor as the do levels are consistent with a much slower fan speed.
★★★★★Martavis Parker· Jun 22, 2026
Exactly what I needed, and I love the gauge comparison to real-life objects.

Sitting close to my phone, coughing lightly, and quietly talking, and I'm as loud as a restaurant.
★☆☆☆☆Miguel Salgado· Jul 12, 2026
Not the least bit accurate. I installed this app to test my stero SPL, and it measures very low around 80 to 90 even when it should be at 140db. The gauge moves to much

The calibration doesn't seem to work as intended. When I put +6dB calibration, it actually applies +12dB instead. Need to be fixed for the quick measurement purpose.

Readings on 2 mobiles side-by-side gives completely different results. Need to calibrate them first.

Inaccurate. Not even close. An exhaust without a muffler was quieter that with, lol. It was 5x louder in person. Don't waste your time.
