Decibel Meter HD provides a way to measure environmental sound levels, showing the approximate dB level.
➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠
The app is based on the current calculations to determine the sound pressure level in dB.
Although we have tested the values with professional equipment, we cant ensure the
absolute correctness by international standard.
It also provides an approximate "decibel guide", so that you know what sound levels correspond to a health hazard.

The iPhones built in microphone is sensitive from 0 to approximately 110 decibels.
Why arent you getting a 0 decibel reading in a quiet room?
A decibel is an actual measurement of sound pressure
and aside from a vacuum chamber or out in space 0 dB is not really possible to read.
An average quiet room will be in the 40-50 dB range.
Latest reviews of Decibel Meter HD Free app for iPhone and iPad
If you want to test a sound system using music from your phone then dont get this app because it gets shut off to run the app...
Not to Shabby
Only goes to 100db
I downloaded another dB meter app and found it was bad (average and current readings were the same.) Tried this one and it was exactly the same with a slightly different interface. Dont even bother.
If you swap apps you must shut it down and restart for it to work again
