Good question.
If the human being concerned is fit, healthy and young, then 20 – 20kHz would be expected. Although some tests show that 15 Hz to 16 Hz can be expected.
By the time you get to middle age (if you are a man, because men’s hearing deterioriates faster than women’s) the upper frequencies drop to about 12kHz to 14kHz.
This is why Mosquito Sounders (https://www.compoundsecurity.co.uk/product/mosquito/) are used to discourage where young people congregate because they are annoying to young people, but older people can’t hear them.
So depending on who the human is, the answer could be 3 or none of the above.
Something to bear in mind when mixing for a younger or older audience.
I believe humans have “Situational Hearing”. For example, if I opened a cookie package at 2am and it only produced a sound at 36000 HZ…my son could hear it…be awakened…and ask for my cookie.
Gary,
That is so true.
I can talk to my wife as loud as I like about gadgets, gizmo and gear and she can’t hear a word!
