dBMeter Pro 4+

I need to be able to get approximate noise measurements as part of may work as a safety engineer. This application allows me to carry a noise meter with me everywhere I go and get a pretty good idea of how noisy any given environment is. Once I start to see levels over 80 dB, I know it's time to pull out my calibrated professional meter to get the "real" data. The recording feature is great too. Being able to take some data samples and email it to myself is very useful. The reference screen is really helpful when I'm trying to get people to understand the degree of noise hazard they are exposed to.

My only complaint is not one that the author can do anything about. The fact that the iPhone mic is limited to 105 dB and that the measurements above 100 dB are therefore less reliable than those below 100 dB is frustrating. Perhaps Apple will address this limitation in a future version of the iPhone.

As a suggestion, I'd love to be able to select 'A' weighting or 'C' weighting for the measurement scales. Perhaps in a future version of the software...

The app works well, I compared reading to a sound meter and the app is damn close to right on to what my other sound meter was reading, the app does a great job for checking dB on dirt bikes when heading to trails with noise bylaws.

This app isn't bad but if the sound is louder than 100 db, there is a red light and there id No reading. I was expecting More from an app at that price. Do not but, The free Apps are just as good.
