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 can't 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.

FEATURES:

► Accurate calculation of the ambient noise in dB

Why aren't 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.
