What are hearing aids, exactly, and why do we at Rampo Hearing & Speech Therapy Clinic offer the best hearing aids? A hearing aid is a discreet electronic device worn behind or in the ear. It amplifies some sounds so that a person with hearing loss can listen, communicate, and take part in daily activities to a greater extent. People with hearing aids can hear more clearly in both quiet and noisy environments. Only about one in five individuals who would benefit from a hearing aid, however, actually wears one. Three components make up a hearing aid: a microphone, an amplifier, and a speaker. A microphone in the hearing aid picks up sound, transforms it into electrical signals, and then transmits those signals to an amplifier. The signals are given more strength by the amplifier before being transmitted to the ear via a speaker. Hearing aids are most helpful for people with hearing loss brought on by damage to the tiny sensory cells in the inner ear, known as hair cells, in terms of improving hearing and speech comprehension. Sensorineural hearing loss is the name given to this kind of hearing loss. The harm may be brought on by illness, aging, or trauma from noise or specific medications. Hearing aids amplify the sound waves that reach the ear. The larger vibrations are picked up by remaining hair cells, which translate them into neural signals and send them to the brain. A person's hearing loss will be more severe and require more hearing aid amplification the more harm they have done to their hair cells. The amount of amplification a hearing aid can offer, though, has practical limits. Additionally, even large vibrations will not translate into neural signals if the inner ear is too damaged. A hearing aid would be useless in this scenario.
