Question

How is sound audible to human
deings through up ear ? Explain​

Answer 1

Answer:

Sound waves travel from the outer ear and in through the auditory canal, causing the eardrum to vibrate. This in turn causes three small bones in the middle ear to move. This results in the transformation of the vibrations into electrical impulses, which are finally perceived by the brain as sound.

The cochlea makes the hearing apparatus and the auditory nerve from it goes to the brain. Working of Human Ear: The external ear catches sound waves and channelizes them to the ear drum, via the ear canal. During compression, the pressure increases outside the ear drum which forces the eardrum to move inwards.

The human ear can easily detect frequencies between 20 Hz and 20 kHz. Hence, sound waves with frequency ranging from 20 Hz to 20 kHz is known are audible sound.
