Is wearing a hearing aid harmful to the ear?

Will wearing a hearing aid for a long time cause damage to the ear?

Hearing aids are an auxiliary device designed for deaf patients to help hearing deafness patients with hearing impairments. The hearing aid consists of three main parts: a microphone (microphone, amplifier) ​​and a receiver (headphone). The microphone is an acoustic-electric transducer that converts the external acoustic signal into an electrical signal. After inputting the amplifier, the sound pressure is amplified to 1 or even tens of thousands of times, and then the amplified acoustic signal is output to the auditory center of the brain. I can hear the sound. Therefore, deaf hearing aids are very useful for patients, just as visual impairments can help us see things more clearly, and deaf hearing aids can also help patients hear the outside world.

Before fitting a hearing aid, the patient needs to perform a series of hearing tests and assessments. Including pure tone audiometry, acoustic impedance and speech testing. If the patient meets the hearing aid fitting criteria, the patient’s own audiogram is selected. Also, for patients who are initially fitted, the fitter will retain the magnification and will not adjust to the maximum volume. After it has been adapted for a period of time, the volume is further increased until the patient is satisfied. Secondly, the maximum sound output of the hearing aid does not exceed the patient’s discomfort threshold, which means that it will not make you uncomfortable and ensure that the hearing will not drop further.

Therefore, for patients with hearing loss, wearing a hearing aid does not affect hearing. In general, with the increase of age, the physiological functions of the human body gradually decline, the inner ear hair cells are apoptotic, and the hearing function is decreased. Also, other underlying diseases (such as diabetes, cardiovascular disease, etc.) may also cause hearing loss. Therefore, the progressive decline in hearing of elderly patients is almost irrelevant to the wearing of hearing aids. Without the use of hearing aids, hearing function and brain dysfunction are certain.

Is it harmful to the ear when wearing a hearing aid for a long time? Experts explain that patients with deafness should actively cooperate with the doctor’s treatment. To effectively control the disease, a hearing aid should be worn.
