At least this PDF shows dB graphs, but the graphs are so noisy that you can't make much out of them. They have fewer harmonic peaks, and the peaks do seem to be up to 10 dB smaller. But the average appears to be pretty similar. Again, hard to be concrete on the differences given the noisy data.
10 dB is a lot (2x the sound pressure) since dB is an exponential scale, but at the peak of 55dB, you're still below the range of a "normal conversation".
Yeah this is when I don't like it. I can't tell if this is truly an improvement. The graph definitely looks tighter, but the overall level appears the same?
I can agree it is "less annoying" but if the loudness is effectively the same then I don't think it's truly an innovation.
