Hearing loss is a common side effect of growing older. Our hearing ability tends to deteriorate with age because the nerves and sensory cells within the ear slowly die out. Presbycusis, a gradual deterioration of hearing in both ears, is a hereditary condition that can further advance hearing loss. Fortunately, a hearing aid can provide solutions for many causes of deafness. Symptoms of Severe Hearing Loss While people often do not recognise a loss in hearing until a friend or family member points it out to them, some warning signs to watch for include: 鈥?Failure to hear the ringing of a phone or alarm 鈥?Difficulty understanding people 鈥?Inability to follow conversations noisy situations 鈥?Turning the TV or radio up higher than previously 鈥?Preference to avoid conversations and interactions with people 鈥?Straining to read lips and expressions to better understand their words 鈥?Tiredness and exhaustion from conversations 鈥?Frequently asking people to repeat themselves 鈥?Depression due to problems with hearing An Audiogram Hearing Evaluation An audiogram is a diagnostic tool that measures a person's hearing loss. Your hearing thresholds for speech and other auditory tones are charted by machine according to your responses to sounds. A trained audiologist will test each ear separately by transmitting tones through earphones. All you need to do is indicate when you are able to hear a tone and in which ear you hear it. Your responses are transferred to the audiogram graph, which shows the decibel level -- or loudness -- of each tone, the frequency -- or pitch -- of each tone, and whether you heard it. If your test results indicate severe hearing loss, a hearing aid can provide superb hearing enhancement by amplifying those sounds that you are no longer able to hear by yourself. While all hearing aids have similar components, you have a selection of styles from which to choose. From virtually invisible models that fit inside your ear canal, to more powerful yet barely visible behind-the-ear styles, your audiologist can help you to pinpoint the best choices for your lifestyle and amplification needs.
