Many friends feel very strange about the term digital hearing aids, this is because we are usually accustomed to only talking about hearing aids, in fact, the hearing aids tested in regular hearing institutions are digital hearing aids.
Since there are digital hearing aids, are there non-digital hearing aids? yes! Today, the voice of the sea will give you a look at the difference between the two.
Digital hearing aids: Intelligent noise reduction according to the environment to improve language comprehension
The hearing aids sold by the national chain of hearing aid fitting institutions are all digital hearing aids, and most of them are products of international first-line hearing aid manufacturers, and the quality and fitting technology are guaranteed.
The digital hearing aid has a tiny chip, the equivalent of a miniature computer, using non-linear amplification technology. The fitter can make targeted debugging according to the wearer's different hearing loss situations, realize small amplification, loud compression, greatly improve the clarity of the sound and the comfort of wearing, and protect the wearer's residual hearing to a certain extent.
Digital hearing aids will automatically analyze the sounds in different environments, which can automatically reduce ambient noise, amplify speech sounds, make it easier for the wearer to hear the human voice, and improve language comprehension, which helps to delay the degradation of the brain's speech center function.
Digital hearing aids not only have high language clarity, good sound quality, and comfortable listening, but also have the advantages of small size, long battery life, high stability, strong anti-interference ability, low failure rate, etc., so now professional fitting institutions use digital hearing aids.
Non-digital hearing aids: All sounds are amplified together, and hearing loss is faster
Most of the hundreds of pieces on the Internet are analog hearing aids, which belong to non-digital hearing aids without smart chips, and cannot adjust specific parameters.
Analog hearing aids use linear amplification technology, just a simple sound amplifier, no noise reduction function, the sound of speaking and ambient noise synchronous amplification, ambient noise and background noise are not well handled. In a quiet environment, the human voice can be heard clearly, but if the sound background is complex, it will cause the wearer to be unable to distinguish between the human voice and the ambient sound, feel very noisy, and the mood is becoming more and more irritable. In the long run, it will also cause secondary damage to the hearing, so that the residual hearing will lose more quickly.
Many people say that the more they wear hearing aids, the more deaf they are, but they actually bought analog hearing aids by mistake. However, there are not a few people who use analog hearing aids, so more and more people have misunderstood hearing aids, in fact, it is not related to digital hearing aids at all, and scientifically matched digital hearing aids can protect residual hearing.
Hearing aids are related to the health of the wearer, and the degree of hearing loss is different for each person, so you must not buy a non-digital hearing aid to wear it, but go to a special hearing institution for fitting.
