Question

how do we hear sound? explain.

Answer 1

Sound waves travel into the ear canal until they reach the eardrum. The eardrum passes the vibrations through the middle ear bones or ossicles into the inner ear. The inner ear is shaped like a snail and is also called the cochlea. Inside the cochlea, there are thousands of tiny hair cells. Hair cells change the vibrations into electrical signals that are sent to the brain through the hearing nerve. The brain tells you that you are hearing a sound and what that sound is.

Take a look inside your ear!

Each hair cell has a small patch of stereocilia sticking up out of the top it. Sound makes the stereocilia rock back and forth. If the sound is too loud, the stereocilia can be bent or broken. This will cause the hair cell to die and it can no longer send sound signals to the brain. In people, once a hair cell dies, it will never grow back. The high frequency hair cells are most easily damaged so people with hearing loss from loud sounds often have problems hearing high pitched things like crickets or birds chirping.

Answer 2

the sound waves are collected by the pinna of the outer ear. These waves paas through ear canal and falls on ear drum . when it falls on ear drum , the ear drum starts vibrating back and forth rapidly . the vibrating ear drum causes a small bone hammer to vibrate . From Hammer vibrations are passed to small bone anvil and then to the third bone stirrup. The vibrating stirrup strikes on the membrane of oval window and passes amplified vibrations to the liquid present in cochlea starts vibrating. The vibrating liquid cochlea sets up electrical impulses in the Nerve cells present in it. These electrical impulses are carried by Auditory Nerve to the brain . The brain interprets these electrical impulses as sound and we can get the sensations of hearing .



Hope it helps . An It's not a. Google copy . I have done it on my own . If it helped u then plzzzz mark it as brainlist.
