What is the auditory channel?
The auditory channel is a tube that connects the pinea or the fleshy outer visible part of the ear and the tympanic membrane or ear drum. Together, the pinna and the auditory channel form an outer ear and measures about 1 inch (26 mm) long. The ear canal has two primary functions: helping the auditory process by training the sound towards the ear drum and protecting the ear drum from injury. In the cartilage outer third of the outer channel, small hair grows perpendicular to the wall of the canal and help clean the channel. Sebaceous glands produce sebum, oily substance formed by fats. Cerumenous glands are produced by Cerumen or Earwax, which helps lubricate the channel and keep it waterproof. Too many ear car may be a problem when it affects and causes temporary hearing loss, which requires removal by a doctor.
The channel channel is responsible for the amplification of the sound and its routing to the ear drum. From a pin to a tympanic membrane, the sound increases by 5 to 15 decibels (DB) in the range of 2,000 to 4,000 Hertz (Hz) as a result of SL resonancefired channel. The human ear is the most sensitive to the sound of this extent and the most vulnerable to damage to sounds that are too loud.
Since the auditory channel is so close to the outside of the body, it is susceptible to many disorders, infections and injuries. Although the depth and curvature of the ear canal provides some protection against injuries, they may still occur or objects may be stuck in the ear. The ear is also a warm, humid organ and can be an ideal environment for the growth of fungal infections. Bacterial infections such as otitis externa, also known as the ear of a swimmer, can infect the outer ear and may damage the ear drum if it is not treated.
cleaning the ear canal is almost never necessary and may be dangerous. The auditory channel is a self -esteem can disrupt the loading organ so that external cleaning can disrupt. Objects such as cotton swabs, inserted in the ear candamage or even pierce the ear drum.
Hearing channel, as well as a nail bed, is a host of a process called epithelial migration. Skin cells move from the tympanic membranes towards the pine, help clean the ear and move foreign objects, ears and throw the hair towards the pin. Some scientists believe that the process is supported by chewing movements that stretch and move the ear channel and can help cells migrate.
