The Ear and Hearing detrimentThe ear is the organ of comprehend and balance in vertebrates.

The innermostpart of the ear maintains equilibrium or balance. The vestibular apparatuscontains semicircular layaboutals which in turn balance you. Any movement by thehead, and this apparatus sends a signal to the brain so that your reflex exerciseis to move your foot to balance you.The ear in humans rest three parts The outer, the middle, and theinner spates.

Those parts ofd the ear are only present in amphibians andmammals, solely the inner ear is present in all vertebrates.The ear can hear in several various ways. They are volume, tack, andtone. Pitch is related to the frequency of the sound wave. The volume dependson the amplitude or intensity of the sound wave. The greater the frequency, thehigher the pitch. earth can hear about 30 and 20,000 waves or cycles persecond. High pitch sounds green goods more of a trebly sound, while low pitchsounds produce a rumbling bass sound.When a person loses these abilities to comprehend sound, it is referredto as deafness. It can be caused by disease, toxic drugs, trauma, or aninherited disorder. Those causes can be classified as conductive, sensorineural,or both.A conductive hearing loss results from damage to those p arts of the earwhich transmit sound vibrations in the air to the fluids of the inner ear. Thistype of damage is usually to the timpani or small bones do itn as ossicles.Ossicles conduct sound from the eardrum to the cochlea. They cannot performsuch an action if the eardrum is perforated, if the middle ear dental caries is fill... ...lly there may be a school in a hospital.Hearing devices are also available.
