Web6. It depends what you mean by "normalised"; it also depends on your software's choices. "Normalised" is a word often avoided by statistical people, because it is ambiguous as between (a) scaled or standardized (e.g. to total 1 or to mean 0 and SD 1) and (b) transformed (approximately) to normality, meaning normal or Gaussian distribution.

WebSine sweep was played by a good loudspeaker of which I have the FR specs. Now these FR charts have different "dB ranges": Mic FR: -90dB to -10dB. Speaker spec: starts at -45dB, moves to 85dB and stays mostly linear.
