How does one measure whether speech in multimedia is 20db louder than 
background sound, from an auditing perspective.

During production its easy enough to control speech and background 
levels, but what I'm looking for is a way to show clients post 
production, that the speech volumn level in a video is less than 20db 
greater than the volume of the background audio in that video. (re WCAG 
2.1 SC 1.4.7)
