Answer 1

Answer:

Velocity Of sound = 340m/s. frequency =? frequency = 34000Hz. This frequency is more than 20,000Hz and thus this sound can not be heard by human ear.The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.
