![]() ![]() In the event that hearing aids are needed, tests help the audiologist assists you in selecting a hearing aid and programs it for your personal use. The results of a hearing test can not only identify loss of hearing, but it can identify the frequencies where the hearing loss has occurred. During a hearing test, the patient listens to sounds of varying frequencies and volumes through headphones and identifies which sounds the patient can hear and which he or she cannot hear. Audiologists can administer hearing tests. Hearing TestsĪn audiologist is a licensed professional who is trained to diagnose and treat hearing disorders. When the dynamic hearing protection device senses loud noises, it blocks the sound transmission, thereby protecting the ear. At low levels, the hearing protection device allows or even amplifies the sounds. ![]() Dynamic hearing protection devices sense incoming noises. Hearing protection can be passive, such as earplugs, or dynamic. Hearing Protectionīecause loud noises can cause hearing loss, hearing protection is advisable for those who are exposed to loud noises such as gunfire, construction machinery, and power tools. Folic acid can help slow the onset of age-related hearing loss and zinc can aid the treatment of tinnitus. Foods high in potassium can aid the inner ear to transmit sounds. Occasionally, hearing loss occurs because loud noises cause damage to the eardrum or the three bones of the middle ear.Īlthough not totally unexpected, nutrition has a surprising effect on hearing. Most frequently, hearing loss occurs because loud noises cause damage to the hairs inside the cochlea. In fact, high-frequency hearing loss due to exposure to loud noises affects 26 million Americans between 20 and 69 years of age. Loud Noises: Exposure to loud noises can cause hearing loss in people of any age.The most common cause of age-related hearing loss is loss of sensitivity of the hairs inside the cochlea. Gradual hearing loss is common as we age, with nearly 50% of those over 75 years old suffering some loss of hearing. Age: Age-related hearing loss is also called presbycusis.There are two primary causes of hearing loss: The brain decodes the electrical impulses as sound. The hairs convert the pressure changes caused by the sounds into electrical impulses that are transmitted along the auditory nerve to the brain. The pressure changes cause movement of the hairs. The vibrations on the oval window cause pressure changes in the cochlear fluid. The inner ear consists of the cochlea, a fluid-filled spiral tube with tiny, sensitive hairs inside. The middle ear functions to amplify the vibrations between the eardrum and the oval window by as much as 20 times. These bones, in turn, vibrate the oval window, which covers the entrance to the cochlea. As the eardrum vibrates, it transmits vibrations to three interconnected bones, the hammer, the anvil, and the stirrup. The middle ear includes the eardrum, which vibrates as sound waves strike it. The outer ear (the portion of the ear we see) funnels and directs sound waves into the ear canal. The ears have three sections – the outer ear, the middle ear, and the inner ear. Here are five facts about hearing and hearing loss: Causes of Hearing Loss Loss of hearing, even partial loss, can leave us disoriented and isolated.
