Hi a hole in my knowledge. If you have a bode plot of an audio voltage and the results are in dbv how can the "A" rating be applied to it. Sound levels are easy to figure ...just look on a chart. But how to relative levels in measuring work. Example at 30 HZ the level (of noise as it was) is -64dbv at 200HZ it is -90dbv. and so on. So clearly the -90 is less noisy, but how much? If "A" weighting is applied what then?
Good Listening
