dB

I'm an ENT doctor and I showed this to our audiologist. A real dB meter costs over $600 and is carried in a small brief case. And you pretty much get the same thing for 99 cents and it fits into your iphone. We tested the two and they were within 10 dB.

When used with the built in mic of the latest gen iPod touch, readings appear to be at least 10-15 dB high. e.g. Quiet bedroom at night in the country reads about 50dB. This is way off. Other apps like "dB Volume" read more correctly around 35dB. This app also does not calculate any weighted results like dBa. Too bad, it does have a nice interface and tagging cap.

Shows only max and peak. Elapsed time.

Needs updated to ios 4! Otherwise good app.

I purchased this for my iPad 3. I installed it 3 times and all I get is a company logo page. I can,t believe I paid for this.

I like this app, because it allows me to save a photo of the event or location along with the measurement very easily. Since other measurements I have made use A weighting, it's a little annoying that this is not an option.

A fun way to measure your environment. The results may surprise you!

Doesn't work, only closed itself when the icon is tapped. Don't buy.
