There are two kinds of hearing AIDS: digital hearing AIDS and analog hearing AIDS. Digital hearing AIDS amplify and compress the sound to the patient's discomfort range, so that the patient can hear it without feeling uncomfortable. In addition, the digital machine is more accurate in debugging accuracy. Digital hearing AIDS are generally debugged through channels. The more channels, the larger the adjustable range, and the clearer the sound that the patient can hear. Analog hearing AIDS are standardized and used to amplify speech and external noise. For patients with sensorineural hearing loss, they may feel too noisy, uncomfortable and distorted, and long-term wear will damage their hearing.
Digital hearing AIDS amplify the sound and compress it loudly to the patient's discomfort range, so that the patient can hear it without feeling uncomfortable. In addition, the digital machine is more accurate in debugging accuracy. Digital hearing AIDS are generally debugged through channels. The more channels, the larger the adjustable range, and the clearer the sound that patients can hear. Analog hearing AIDS amplify speech in a standard and unified way, and also amplify external noise. For patients with sensorineural hearing loss, they may feel too noisy, uncomfortable and distorted.
Hello, the earliest hearing aid is analog hearing aid, which uses the original analog linear amplifier circuit and relies on manual adjustment, and now it has been eliminated. The digital hearing aid adopts nonlinear amplification circuit, which can automatically judge the sound situation of the external environment and automatically control the amplification level according to the user's listening comfort, thus avoiding the phenomenon that the simulator user can't hear in a low voice and feels uncomfortable in a high voice. By connecting with the computer through the programming line, there can be more than a dozen fine-tuning parameters, more adjustment parameters and greater flexibility, which can adapt to the hearing changes of the hearing impaired for a long time. All-digital hearing AIDS can distinguish and suppress environmental noise, so the sound quality is clear, loud and soft, and not noisy. The actual effect of enhancing speech signal in digital signal processing of digital machine is that the user's language intelligibility is much higher than that of simulator, which can improve the speech intelligibility in noisy environment. Suppress acoustic feedback without affecting normal amplification. More and more people choose digital hearing AIDS, and the response is very good.
The main difference between analog hearing aid and digital hearing aid is that analog hearing aid can not be tuned according to the hearing loss of patients, but can simply amplify the sound, while digital hearing aid can be tuned according to the hearing loss of patients, which will be better for the wearing comfort of patients. Digital hearing AIDS are generally debugged through channels. The more channels there are, the wider the adjustable range will be, and patients will hear more clearly. At the same time, it has more functions than analog hearing AIDS.

First, the amplification circuit is different. The analog hearing aid adopts linear amplification circuit, while the digital hearing aid adopts nonlinear amplification circuit, which can automatically judge the sound situation of the external environment and automatically control the amplification level according to the user's listening comfort, thus avoiding the phenomenon that the simulator user "can't hear in a low voice, but feels uncomfortable in a high voice".
Second, speech intelligibility in noisy environment Most all-digital hearing AIDS can automatically identify the noise with fixed frequency, and effectively compress it in noisy environment, focusing on the sound with speech frequency, thus effectively improving the speech intelligibility of users.
Third, the design of Monson digital hearing aid can automatically select the calculation formula to calculate different Monson according to the user's different hearing loss, age and sound perception, so as to meet the user's hearing needs to the greatest extent.
Fourth, frequency division amplification and multi-program control digital hearing AIDS can use frequency division technology. The application of multi-band processing technology ensures the accuracy and comfort of hearing compensation for patients. Digital hearing AIDS can set different listening programs according to different use environments of users. Such as quiet environment, noisy environment, music environment, induced environment and so on.
Fifth, the failure rate is very low. Digital hearing AIDS adopt microcomputer chip technology, which can fully control users' hearing compensation needs, minimize and reduce users' self-adjusting fine-tuning switches, and effectively avoid hearing aid failures. .
In a word, all-digital hearing AIDS have high language clarity, good sound quality and comfortable listening. More and more people choose digital hearing AIDS, and the response is very good.
