This is the best app I have found, I'm using a Poco f7 pro and have an independent sound meter which enabled me to calibrate it. I had to add +22 which seems a lot, but once done the meter is good. Other apps I tried were closer to where they should be sound wise, but adverts or not being able to set the time interval for reading and similar things made me pick this one. Unfortunately it stopped working properly after a phone update.

I tried several apps for measuring sound volume and this is the only one that gave what I would call a correct reading.

I have hyperacusis (the result of a stroke and can hear exceptionally well) and stay near a shopping centre. I need an acoustic glass sliding door and windows that prevents the loud traffic, the reversing beep beep sounds, offloading sounds and motorcycles from waking me up at 04h30 in the morning when background noise are minimal. So I downloaded this App, and what an experience. I can now tell what the frequencies are so that my door and windows can be made to the specific frequencies.
