Hearing impairment in the elderly is not only a decline in the function of the auditory organ itself, but is often accompanied by auditory conduction pathways and pathological changes in the auditory center, which reduces the ability to analyze, process and respond to incoming sound signals, thus predicting and evaluating hearing aids. When you have a hearing compensation effect, you need to have a good understanding of it. Before the hearing aid fitting, they should know as much as possible about the cause of deafness, and try to eliminate the hearing impairment caused by otogenic factors, such as senile dementia, cerebrovascular accident, multiple sclerosis, brain disease, and hearing and treatment. Caused by “deafness.” At the time of the consultation, they can understand their behavioral cognition and auditory responsiveness through purposeful verbal communication, and indirectly judge their acceptance of hearing aids and the hearing aids may help them. In general, people who actively participate in social activities and collective communication, have a strong desire for knowledge, and constantly ask questions are easy to accept and can continue to use hearing aids.
Older people have a good listening experience in the past. They often have high expectations for hearing aids. They require hearing aids to be free from noise and distortion, and to listen to speech without being affected by distance and environment. In short, I hope to restore the hearing feeling before the deafness through the hearing aid. Although some of these requirements are not what the hearing aid can do, the fitter should try to get the hearing aid from the patient through the fitting skills and fitting experience. Before the fitting, objectively explain the working principle of the hearing aid and the help it may provide. Do not over-exaggerate the role of the hearing aid to avoid the patient’s high expectations for the hearing aid. At the time of fitting, the characteristics of the auditory function of the elderly should be fully recognized and utilized. Most of the deaf elderly have relatively good hearing below 1000Hz, and there is a significant decline from 2000Hz. When the hearing aid is first fitted, the hearing compensation of the low frequency part should not be too high. Our experience is that 250 and 500Hz are at least lower than the target. The gain value is 5dB, and at the same time, suitable pores are prepared on the ear mold or the hearing aid, otherwise the rejection phenomenon occurs due to the influx of low frequency noise and the obvious plugging effect. Some deafness caused by drugs, noise and trauma, there will be obvious “re-vibration” phenomenon. At this time, if the hearing aid is only debugged according to the patient’s air conduction audiogram, it will not receive satisfactory results. Therefore, when fitting, it is necessary to input the bone conduction valve, the comfort valve, the discomfort valve and the speech recognition valve into the computer, and refer to the fitting formula suggested by the fitting software to select the target patient’s target gain value. Some fitters emphasize that the patient should be able to hear the consonant components of the speech in order to achieve the purpose of hearing clearly, and excessively increase the gain of the high-frequency part, resulting in the unbearable speech sound, but reduced the comfort of the hearing aid. Affects the patient’s trust in hearing aids. After wearing the hearing aid for the first time, I felt unresponsive when I spoke speech. It was expressed that I could only hear the voice and could not understand the meaning quickly. This is because patients with senile sputum have a lack of sufficient intensity of speech stimulation for a long time, more or less accompanied by changes in auditory responsiveness and verbal cognitive ability, and the speed and processing speed of external speech information is reduced. It will change afterwards.
