I am mechanical engineer and I have experience in environmental engineering; when you are at 99 and the sound gets louder, you expect the reading to increase. **Developer response:** Hi, thank you very much for using my app and sharing your review.

The 'A' weighting filter would show much lower levels in most situations. **Developer response:** Hi, thank you very much for using my app and sharing your review.

Not accurate ### 4/5 — Review *2016-09-17, version 1.6* Seems to be consistent and picks up really good. Overall it's a good app ### 1/5 — Needs work *2016-08-05* I was excited to get a decibel meter on my phone. But quickly discovered that it isn't even close to being accurate.
