How to equip hearing aids for old people

The hearing impairment of the elderly is not only the decline of the function of the hearing organ itself, but also the pathological changes of the auditory conduction pathway and the auditory center, which reduces the ability to analyze, process and respond to the incoming sound signals. Therefore, we should have a full understanding of this when predicting and evaluating the effect of hearing compensation of hearing aids. Before hearing aids are matched, they should know as much as possible about the causes of deafness, and try to eliminate the hearing impairment caused by otogenic factors, such as Alzheimer’s disease, cerebrovascular accident, multiple sclerosis, brain diseases and hearing processing diseases. Through purposeful speech communication, we can understand their behavior cognition and auditory response ability, and indirectly judge their acceptance of hearing aids and their possible help. Generally speaking, 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 adhere to the use of hearing aids.

Old people have good listening experience in the past. They often have high expectations for hearing aids. They require hearing aids to be free of noise and distortion, and the listening of speech is not affected by distance and environment. In a word, we hope to restore the sense of hearing before deafness through hearing aids. Although some of these requirements can not be achieved by hearing aids, the matching personnel should try to make the patients accept the help of hearing aids through matching skills and experience. Before matching, we should objectively explain the working principle and possible help of hearing aids, and do not overstate the role of hearing aids, so as to avoid the patients’ high expectations of hearing aids. We should fully recognize the characteristics of the hearing function of the elderly and make use of them. Most of the deaf old people have a relatively good hearing below 1000Hz, but a significant decrease from 2000Hz. When the hearing aid is first tested, the low-frequency part of the hearing compensation should not be too high. Our experience is that 250 and 500Hz should be at least 5dB lower than the target gain value, and at the same time, appropriate air holes should be prepared on the ear mold or hearing aid, otherwise, due to the influx of low-frequency noise and obvious ear blocking The phenomenon of refusing to wear was found. Some deafness caused by drugs, noise, trauma and other reasons will have obvious “rejuvenation” phenomenon. At this time, if only according to the patient’s air conduction audiogram to debug the hearing aid, it will not receive satisfactory results. Therefore, when matching, it is necessary to input bone guide valve, comfort valve, discomfort valve and speech recognition valve into the computer together, refer to the matching formula prompted by the matching software, and select the target gain value of the appropriate patient. Some match examiners emphasize that the patients can hear the consonant components in the speech as much as possible to achieve the purpose of hearing clearly, and excessively increase the gain of the high frequency part, resulting in the dry and intolerable speech sound, but reducing the comfort of the hearing aids, affecting the patients’ trust in the hearing AIDS. After wearing the hearing aid for the first time, I feel sluggish in speech communication, which means that I can only hear the voice and can’t understand the meaning quickly. This is because the elderly patients with deafness do not have enough intensity of speech stimulation for a long time, more or less accompanied by changes in auditory response ability and speech cognitive ability, and the processing and comprehensive speed of external speech sound information decline, which will change after a period of time.
