![]() If you have any doubts or queries on how our ears work, leave us a comment below or contact us through our website or social media pages. They’re mostly responsible for rotary motion, or motion not in a straight line. Instead of sound waves, these tiny hairs react to body movements. Like the cochlea, the canals are filled with liquid and lined with hair cells. ![]() For example, hearing centres such as Audifón offer clients simple instructions for completing a series of hearing rehabilitation exercises at home to help the ears recognize certain frequencies and improve hearing levels. Semi-circular canals are tubes coiled within your inner ear. Finally, the Organ of Corti transforms the mechanical energy of the sound waves into nerve energy by creating electric impulses that are sent to the brain through the auditory or vestibulocochlear nerve.įailure to receive these electric impulses in the brain is a sign that the ear is defective or damaged, and is a warning that there is something amiss in our auditory system.Īuditory training can help some people who suffer deafness or hearing loss to recover the ability to receive and process sound and understand spoken language more fluidly. The inner ear: includes the cochlea, a structure that has a spiral shape similar to a snail shell, and is located in the bony labyrinth, which has several membranous sections filled with fluids called endolymph and When these liquids move, they create fluctuations in the cochlea’s hair-like structures called stereocilia. The tubes are usually made of plastic or metal.This ensures that the pressure on either side of the eardrum is balanced and that sound can be heard correctly. A narrow tube of approximately 3.5 cm in length, called the Eustachian tube, connects the ear to the outer part of the nose and acts as an equalizing valve. During an underwater dive or a rapid descent in an airplane, the tube may remain tightly closed. An infection in the middle ear (otitis media) is the most common. The tube is closed at rest and opens during swallowing so that minor pressure differences are adjusted without conscious effort. The ear is divided into three sections: the outer ear, middle ear, and inner ear. These bones form a bridge between the eardrum and the inner ear through the oval window that covers the cochlea. The eustachian tube helps ventilate the middle ear and maintain equal air pressure on both sides of the tympanic membrane. The middle ear: includes the ossicles, three minuscule bones called the malleus, incus and stapes (the latter being the smallest bone in the human body).The eardrum is circular and flexible, and begins to vibrate as the incoming sound waves strike it. ![]() The external ear: formed by the pinna and the external auditory canal, which receives sounds and transmits them to the middle ear via the eardrum.
