Senile sputum needs to be worn hearing aid What?
Senile sputum is a very common phenomenon in the elderly population, epidemiological surveys show that: pure-tone hearing is greater than25dBAs standard, in55-64Incidence among the aged population10.1%, with increasing age (65-74Years old), the proportion of hearing loss has also increased to26.2%.
At present, the Chinese elderly population has reached1.3Billion, accounting for the proportion of the total population11%, calculated to2025Year2.84Billion,2040Annual growth to4More than 100 million. Senile sputum has become one of the most common chronic diseases in modern society. However, some people suffer from premature hearing loss due to genetic factors and environmental factors (such as noise exposure, smoking, ototoxic drug application, high blood pressure, and high-risk factors in a highly stressed working environment). There is a trend towards the development of middle age.
Senile sputum causes hearing impairment in the elderly, affects the patient’s speech communication, and gradually reduces communication with the outside world, further aggravating the patient’s loneliness and seriously affecting the patient’s quality of life. At the same time, it has weakened the living and working ability of the elderly and has brought many adverse effects to economic development, family harmony and the happiness of the elderly. From the perspective of social needs, we should give enough attention to senile sex.
Although hearing aids are the most effective means of rehabilitation for senile convulsions. However, the basic knowledge of the audiology of the elderly is lacking, the influence of psychological barriers and the inability to correctly understand the correlation between consumption and quality of life. Therefore, there is a lack of initiative in the selection of hearing aids. Hearing aid The acceptance rate is not high. In developed countries15%~30%The senile sputum patients are equipped with hearing aids, and the matching rate of hearing aids for senile sputum patients in China is lower.
The reason is, first of all, the elderly do not pay much attention to auditory degenerative diseases. Many people think that when they are older, hearing loss is a matter of course. Secondly, there are also misunderstandings in the concept of hearing aid selection. It is believed that wearing a hearing aid is a symbol of “scorpion” and “aging”. Again, everyone’s expectations for hearing aids are too high, and they hope to have the same effect as glasses, which can compensate for the loss of hearing. Also, as the age increases, it becomes more and more difficult to place the hearing aid, adjust the volume of the hearing aid, and replace the battery.
In fact, patients with senile deafness should have early hearing assessment and hearing aid selection, so that patients can master the use of hearing aids in the early stage and are more willing to accept hearing aids. The research found greater than70Older senile sputum patients are less likely to receive hearing aids than older patients, and may be associated with older patients, need for fine movements during hearing aid use, further decline in inpatient hearing, and worsening speech recognition rates. Neurons in the aged brain, as a response to injury and degenerative lesions, still have the ability to generate new catapults to replace the diseased staples to repair the neural circuits. This type of hearing loss-induced neuron remodeling is particularly evident in the auditory cortex. At present, animal experiments believe that the amplified acoustic stimulation of the hearing aid can accelerate the auditory nerve remodeling of the auditory center. The choice of early hearing aids for senile sputum will slow the development of auditory degenerative lesions and facilitate the protection of hearing function.
It has been clarified that bilateral hearing aid fitting can prevent hearing deprivation. Patients with bilateral hearing loss, such as wearing a hearing aid with only one ear, often lead to hearing deprivation in the hearing aid ear, the so-called suprathrone asymmetry. This phenomenon may be related to neuronal competition, and neurons in the hearing aid ear are activated, while contralateral neurons are not activated.
The observation of the hearing aid effect in patients with mild hearing loss and moderate to severe hearing loss found that the hearing aids of patients with moderate to severe hearing loss had a significant benefit after matching. The hearing recognition rate of patients with mild hearing loss was significantly improved in speech background.
Senile sputum is not only manifested in the decline in hearing, but also in the decline in frequency resolution and time resolution. The maximum sound that the patient can tolerate has not only not improved, but may even decline. It is expressed as “small voice can not be heard, loudly can not stand.”
