Limitations in perception of frequency in human hearing correspond to physical structures of the cochlea in the inner ear, directly related to mechanical properties that dictate at which frequencies such structures can resonate. At the microscopic level this amounts to movements of tiny hairs in reaction to sound energy.

Why do humans use sounds they cannot hear?
the sound caoacity for human beings are from 20 hz to 20000 hz.we use ultrasound to check the defects of metals
What frequency of sounds can people hear?
12hz -20000 hz.
Humans can hear frequencies between?
The audible range of frequencies for humans is, on average, between 20 Hz and 20kHz, although it varies between individuals. As humans age, however, this range normally decreases, especially on the higher end of the range.
Why can you hear better in the rain?
you cant because u hear rain.
Why cant you hear ultra sonic sound?
we can not hear ultra sonic sounds because u can not hear them
What frequencies of sound can humans hear?
typically 20-20000 Hz - but this range will decrease with age

Can animals hear stuff humans cant?

Can animals hear sounds that humans can't hear?
yes, animals hear thousands of high pitched noises that we cant hear at all. hope this helps :)
What is the highest young children can hear?
20000
Why we cant hear the sounds of frequency more than 20000 Hz. Reason?
These sounds have got a specific name. They are known as Ultrasounds. We can hear them, but the problem is that they cause the eardrum to vibrate too much and hence they are incomprehensible.
Why do humans use whistles that humans cant hear?
most animals like dogs can hear more higher pitches than us so they can hear it, you should not blow it too much, because it will hurt their ears.

Do sound waves stop when losing hearing?
in a way, but there are still some there, humans just cant hear them.
How does the Australian cassowary hear?
The cassowary makes a deep, booming, "thrumming" sound. The frequency can be very low, down to 23 Hertz. At this depth it is almost inaudible to humans who can, on average, hear from 20 to 20000 hertz. It is thought that low frequencies are heard better amidst the dense vegetation of the rainforest.
