Surely the article is midtoane when it used the unit kHz for the frequencies, the sine waves used were
> Low frequency: 25kHz
> Medium frequency: 200kHz
> High frequency: 1000 kHz
All of which are very high and well above the range of human hearing, so I think the units should be Hz instead.
Do we have a paper source for this?
- seba_dos1 8y agoSome young people may just reach that "low" range and be able to catch the unpleasant existence of a 25kHz sound source :) I was able to hear it when I was circa 13yo IIRC. But yeah, for an adult, that would be truly exceptional.
