acoustics Comparison

Started by aktr512 February 2, 2014
Hii
I am trying to compare two .wave files(sounds of a device).
one is reference file and i have to compare new file with it.
how should i consider the loudness of sound?
i am using cross-correlation , coherence and positive peaks difference techniques in parallel 



There are several "loudness models" with varying complexity.
Zwicker, Moore, etc.
Simplest thing is to just A-weight and then RMS.
