What is air guidance?
Air guide is the way the sounds reach our ears. It is a way in which almost all sound is transmitted except for our own voice. The voice of the listener is transmitted by bones. The sound
passes through the fastening channel to the eardrum through the air conductivity process, causing the vibration of the ear drum. These vibrations are transmitted to three smaller bones in the middle ear called osicles. These vibrations or sound waves and then travel to the cochle. The ear canal is a tube running from the outer ear to the middle ear. It starts at Pinno, also known as the ears, which is the outer part of the ear. The ear canal is then traveling to the ear drum.
The ear drum is a thin membrane separating the outer and middle ear. It is where the sound is transmitted to the aspen, a small bone that transmits the sound to the cochle. Cochlea is part of a labyrinth or inner ear. Labyrinth is a passage filled with a liquid containing a vestibule of the ear, cochle and semicircular channels. He is responsible for hearing and balance. Liquid inside a catHlea moves in response to vibrations. Cilia inside Kochle then begins to move. This movement converts vibration into electrical signals. These electrical signals are then transported to thousands of nerve cells through neurotransmitters or chemicals that pass to nerve pulses.
hearing tests can explore how well a person hears. Hearing test for air hearing control and bone hearing. Air guide or pure tone hearing test uses headphones and a number of short beeps at different intensities and intervals. The bone management test includes a bone oscillator or a vibrator placed on a mastoid. The mastoid is a bone placed behind the ear.
In the loss of air guidance, the results of the bone guide test are better. This difference is referred to as air/bone gap . Hearing loss involving air guidance and bone guidance is called and mixed loss .
hearing loss in the air can be treated with hearing aids. Hearing aids intensify the sound. Kochlear implants are another option to treat hearing loss. This surgically implanted electrical devices, also referred to as bionic Ear , provide individuals with a sense of sound who have serious hearing problems or for those who are considered deeply deaf.
