Normal high frequency hearing level
The commonly stated range of human hearing is 20 to 20,000 Hz. [5] [6] [note 1] Under ideal laboratory conditions, humans can hear sound as low as 12 Hz [7] 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. [8] Ver mais Hearing range describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is … Ver mais In humans, sound waves funnel into the ear via the external ear canal and reach the eardrum (tympanic membrane). The compression and rarefaction of these waves set this thin membrane in motion, causing sympathetic vibration through the middle ear bones (the Ver mais Cats have excellent hearing and can detect an extremely broad range of frequencies.
