Why is loud noise bad for your hearing?

Answer 1

The inner ear contains very delicate hairs which detect sound vibrations of different frequencies based upon their location inside the cochlea, which focuses sound. A sufficiently loud sound can damage these hairs. Not only does this reduce your ability to hear, but it also can leave you with an annoying condition called tinitis, in which you hear a constant sound.

Answer 2

The ear has three areas: the outer (visible part of the ear), middle, and inner ear. A thin membrane, called the eardrum (tympanic membrane), divides the middle and outer ear. When we hear, sound vibrations, or sound waves, funnel through the outer ear and down the ear (auditory) canal, where the sounds hit the eardrum, and cause the eardrum to vibrate.

These vibrations are passed through the three small bones in the middle ear - the malleus (hammer), incus (anvil), and stapes (stirrups). From the middle ear, the sound vibrations are transmitted to the inner ear (vestibule). Tiny hairs in the cochlea (a snail-shaped organ in the inner ear) transform the sound vibrations into nerve impulses. The impulses are transmitted to the brain through the auditory (cochlear) nerve.

Excessive exposure to loud noise can damage the tiny hairs in the cochlea and lead to hearing loss. Generally, this type of hearing loss is reversible (except in some cases of a sudden, very loud noise, such as an explosion).

However, over time, repeated exposure to loud noise can cause permanent damage and hearing loss. This condition is known as noise-induced hearing loss.

Answer 3

loud noises affect your ears by hearing noises louder thanks 85 decibels. Also cold weather can harm your earmuffs or a hat to cover your ears.

Answer 4

Loud enough noises can damage the tiny tiny parts in the ears that reacts to the noise and send signals to the brain. If they break, no more signals and no more hearing.
