Myth 1: I can still hear it. There is no need to match it now.

There are many people who think that their hearing is OK and they are not willing to accept the help of hearing aids. In fact, this is not right. Hearing aids are generally needed for hearing loss below 40 dB. Theoretically speaking, hearing aids can delay the phenomenon of hearing loss and maintain the original speech recognition ability.

Myth 2: is it possible to choose a big brand and multi-channel hearing aid with high price to be the same as a normal person?

As the name implies, hearing aid is a kind of hearing aid device. No matter how good its function is, it can’t replace a pair of good ears of people. Because it is a machine after all, people with hearing loss often spend a lot of money, and they will feel cheated if they fail to achieve the desired effect. It’s the same as making dentures. In theory, multi-channel hearing aids are better than single channel hearing aids. Now, multi-channel hearing aids have been the main way for manufacturers and fitting centers to publicize. Each manufacturer has its own interpretation for the definition of channels. There are more than a dozen or dozens of channels. Some brands have only a few channels of hearing aids The channels are adjustable and the lines are the same as the virtual ones! At present, most Chinese people don’t know much about hearing aids. When choosing a brand, try to choose a professional brand, especially when matching hearing aids for children, be sure to choose professional listening products.

Myth 3: hearing loss in both ears with only one hearing aid

70% of the patients who wear hearing aids are not satisfied with the results in the later stage, especially in the environment with loud noise or noisy people. They often complain about how I wear hearing aids or: “can’t hear what people are saying?” patients with hearing aids on one ear often have this phenomenon. Often put the responsibility on the hearing aid, saying that the hearing aid is not good, and so on. Many experts and experiments have proved that wearing the hearing aid with two ears can significantly improve speech recognition rate, improve signal-to-noise ratio, have more sense of direction than one ear, can increase the three-dimensional sense of sound, and make the sound clear and full.

Myth 4: I don’t need a digital hearing aid. Just buy a box or a few hundred yuan one.

The voice of < a href = "http://www.sqhearing.com/tlkp/450.html" target = "blank" > digital hearing aid < / a > is not only clear, but also can well protect the residual hearing of patients. Nowadays, the mainstream digital hearing aid basically adopts a wide dynamic compression and amplification circuit called WDRC, which can improve the dynamic range of patients with sensorineural deafness and ensure that the hearing aid can In order to adapt to all kinds of acoustic environment, its amplification principle is: the amplification ratio of low sound is large, the amplification ratio of loud sound is small, and the useful signal is compressed into the dynamic range of the patients with hearing impairment. Because of the diversity of hearing loss curve, the hearing aid of single channel compression is difficult to match the hearing loss of each frequency point of patients accurately, and multi-channel compression is more targeted than single channel compression. There are also multiple microphones that are more perfect for receiving sound than a single microphone.
