> Since loudness is a psychophysical percept, it's also dirty pool to speak of loudness in this way. It's worth noting that there are standards for loudness as well. For example: The FCC broadcast spec for commercials uses ITU 1770, which involves a filter. The resulting measurement is then labeled in units of dB LKFS. (LK are filter params, which are fixed by the spec, FS is full-scale, ie this is done digitally. (As an aside, video streaming could sure use some more uniformity for its inline commercials too.))

I've noticed very recently that Youtube started to play commercials louder than whatever I was watching. I don't remember google stooping to such tricks ever before,

  Not saying you're wrong, but often the ads seem louder than the content without actually dissipating any more power; this is because ad studios are good at dynamic range compression and other sound engineering witchcraft.

  > I don't remember google stooping to such tricks ever before I kinda doubt that anyone has consciously tried to make the commercials louder than the content. It's a tough problem to get right: The television industry has been at it a lot longer, and they still barely make it work. The digital outlets still seem to be finding their footing on this issue. FD: My biz delivers commercial content to TV, digital and cable outlets (and we normalize the audio). Normalization used to be a bit of a black art, but failure to get the audio levels right results in FCC fines to the stations, so you have to work hard to make it happen.

  Youtube plays commercials? ;-)

the Phon and Sone scales i'm familiar with. They're both based on pure-tone thresholds, though, so I'm not totally sold on their applicability to broadband sources.
