Can you convert dB to dBA?

To start with dBA refers to decibels (dB) with an "A" weighting. You cannot convert from dBA to dB without a recording. If you have a recording, then select the "flat" or "C" weighting on your analyzer to get a dB reading.

How do you calculate dB and dBA?

Firstly we need to divide each value by 10 and then anti-log each value. The simplest way to do this is to use the formula 10 ^(L/10) where L is the value in each cell. Now we add all of these values together, log this value and multiply it by 10 to give the final dB(A) value.

How does dBA correlate to dB?

You will often see noise levels given in dBA (A-weighted sound levels) instead of dB. Measurements in dBA, or dB(A) as it is sometimes written, are decibel scale readings that have been adjusted in an attempt to take into account the varying sensitivity of the human ear to different frequencies of sound.

What is the difference between dB and dBA?

What Is the difference between dB and dBA? dB sound pressure levels are unweighted. dBA levels are "A" weighted according to the weighting curves to approximate the way the human ear hears. For example, a 100 dB level at 100 Hz will be perceived to have a loudness equal to only 80 dB at 1000 Hz.
