How good's your hearing

Marklings
Having said that the vast majority of readers of this forum would not be able to hear anything above say 12 / 13 K Hertz. So any discussion about 100k etc is snake oil.

Typical hi-hats are usually between 300-3000 Hz dominant frequencies, and can extend up to 10-17k Hz for crispness, “air” and sparkle.

A worthy note incidentally, is that many audio engineers insist that even though one cannot conceivably hear beyond 20k, one can feel beyond 20k, which is why they are adamant about capturing ALL the recorded frequencies (especially metallic percussion). They feel that one can sense those “inaudible” frequencies, thus making the recording richer, and more open sounding.
