2, the principle of comfortable volume: it is to ensure the comfort of the volume and ensure that loud voices will not affect and hurt patients. For patients who have just worn hearing AIDS, we would rather turn down the volume than make patients feel uncomfortable or uncomfortable because of the excessive volume. We can test the patient's response to noise by gradually increasing the sound of clapping or striking the table. Excessive volume will cause dizziness, headache, deafening, loud noise and other situations. If the sound is too loud, you can appropriately reduce the volume (gain) or the maximum output. Moderate volume can ensure that the amplified sound of the hearing aid is helpful to patients and fully embodies the excellent functions of the hearing aid.
3. Principle of "simplicity" before "complexity": With the development of science and technology, the functions of hearing AIDS are changing with each passing day. There are more and more debugging functions, and the adjustment methods are more and more refined. Such as intelligent noise reduction, compression technology, feedback suppression, frequency band adjustment, wireless remote control and so on. Some fitting people may find it difficult to start with the complex debugging function of the fitting interface. At this time, we should follow the principle of "simplicity" before "complexity": 1, and solve simple problems first, such as volume and noise reduction; Then gradually solve the problem of comfort and clarity. 2. First use simple methods to debug, such as "best fitting", and then give priority to debugging through the function of "quick fitting".
4. The principle of "easy" before "difficult": In the process of debugging hearing AIDS, we should also follow the principle of "easy" before "difficult". Solve simple problems with simple methods first. For example, listening to 20 ITC, if the patient reports that the hearing aid is noisy, then we can solve the noise problem in the following three ways. One is the method of frequency reduction, the other is the function of super static king, and the third is the function of intelligent noise reduction. Which method is specifically used to solve the patient's noise problem? Let's first understand the differences between these three treatments. Because most of the environmental noise is distributed below 500Hz, it is customary to reduce the frequency gain to reduce the noise when debugging hearing AIDS. We know that changing the frequency is actually adjusting the tone. Therefore, this method obviously changes the sound quality characteristics of hearing AIDS. Ultra-quiet king is a unique technology in Austar hearing aid products, which is mainly used to adjust the interference of subtle noise in the environment, such as computer mainframe, fan, air conditioner, microwave oven and so on. Listen to the ultra-static control of 20 and fine-tune it in 20 channels. The intelligent noise reduction function only needs to select the noise reduction level (6, 10, 13, 17). Follow the principle of "easy" first and then "difficult", you can quickly choose and give priority to intelligent noise reduction processing function.
Because the hearing loss duration, nature, degree, speech resolution and effect expectation of each hearing-impaired patient are different, the hearing aid we choose may not meet the requirements of hearing-impaired patients. We need to understand that we are assembling hearing AIDS for people, not audiograms. Wearing a hearing aid requires a process of adaptation and gradual debugging, as well as a process of gradually improving the speech recognition rate. People's listening to sounds is divided into: listening-listening clearly-understanding. For hearing-impaired patients who just wear hearing AIDS, first of all, we should consider whether they are clear and easy to understand, but first of all, we must ensure that they can easily hear more sounds; The second is to consider whether you can hear clearly and understand. Being able to hear clearly is the recognition rate of the sound you hear. Understanding is a higher level requirement, and it is a process in which the speech center of the brain encodes and decodes sound signals. For example, we may be able to imitate the sound completely over and over again, but it doesn't mean that we must understand the meaning or meaning of the sound.
After debugging, make appropriate evaluation according to the patient's own situation. Ensure the hearing clarity and comfort of patients as much as possible. Improve the satisfaction of hearing-impaired patients, increase the return rate of old customers and benign publicity.
