While sitting in my truck in our yard with the motor off in near silence the meter was bouncing between 75 and 82 dB. Closed the app to make sure there weren’t any other apps running in the background restarted it and got similar results. Calibration is Way Way bad.

Ok so it’s very sensitive and idk what ppl would use this app for I just downloaded it just to download it cuz y not but I think it wastes ur gigabytes

Measures exactly the same whether in a busy store with lots of noise or in a silent room at 3am. Would love to see it work... if only it did.

Sitting in a quiet room, this app shows 70db. Maybe it hears my tinitus; this, it adds 20+ db to reality. I asked my 8-year old son and my Lady to engage in basic conversation with me to develop a baseline. The app recorded 85-95db while my phone was in its Lifeproof case, which degrades sound transference more than the people I talk to on the other end would prefer. I then walked outside to record the db of my 10kw generator. The app showed the exhaust was around 105. The generator has been shown in previous tests with several other apps (and the digital microphone our industrial hygienist uses at my place of work) as around 85. I will keep looking.

I'm not sure if it was my sleep deprived perception or a temporary bug, but the one-star review I wrote because the app seemed over sensitive is not appropriate. It seems to work the same as other apps.

Way to sensitive on iPhone X. Totally quite house, not even an air conditioner running and it reads 60db.

The calibration is off on the over-sensitive side. My talking quietly...just loud enough to activate Siri with a (sturdy install, not wobbly) ceiling fan in the background and the iPhone about 12-14 inches away from my face...registered at 75-80 dB. The good news is it's consistent, just need to be able to calibrate. My 2-star rating would easily be 4-5 stars if there was a way to calibrate or establish a relative baseline.

It is very useful for something like a very noisy home. And it helps you not Lou’s your hearing. But it is a little sensitive so it is a little bit off.

When comparing the decibel readings of this app compared to several other db meter apps that I downloaded, this one consistently reads 15 to 20 db higher. In actual loudness, that is a huge difference since decibels are measured on a logarithmic scale. If you’re looking for accuracy, look elsewhere. I’d suggest the free NIOSH SLM app which has more features and seems to be way more accurate.
