@dec23k This is rubbish. 750Hz is around F5#, the F# in the octave above middle C. So the claim is that if you put on your ANC headphones and run your fingers up the white and black keys, then a few notes will be particularly louder. If you have a piano or a keyboard, give it a go now. See for yourself. One of the cases where a cheaper instrument is better. If this really existed, audiophiles would be besieging the HQs of Sony, Bose and Apple over poor headphone performance whenever near the huge amount of popular music in F# minor. --- So of course I had to read the paper. Turns out the claim isn't that 750Hz is louder. The claim is that 700-800Hz is psychometrically more noticed. So this need not be a feature of ANC at all. It could be a feature of humans. And why are these frequencies more noticed as bicycle bells by human listeners. That would be because these frequencies are often used by bicycle bells. People pay more attention to the things they are listening for. Shocked I am.
