With the aging of the population structure, more and more people suffer from hearing impairment.According to statistics, at least one-quarter to one-sixth of the population over XNUMX have hearing problems.What kind of person should wear it Hearing aid ?Or how much help can hearing aids provide?There is no clear answer, and it varies from person to person. It needs to be considered from many aspects:
The first is the type of hearing impairment.After the sound is collected by the outer ear, it is transmitted to the middle ear to be amplified, and then transmitted to the inner ear, where the sound waves are converted into electric wave stimuli, and then transmitted to the auditory center through the auditory nerve, and its meaning is understood.Hearing impairment is generally divided into conductive type, sensory type and mixed type according to the location of the disease. The conductive type is better for wearing.Generally speaking, after choosing a suitable hearing aid, on the one hand, it can help understand the sound, and it can also prevent the auditory nerve from degrading.
第二是要考虑听力损失的严重程度。听障依程度分成轻度（26-40分贝），中度（41-55分贝）、中重度（56-70）、重度(71~90分贝)及极重度（大于90）。过去的观念认为轻度的听障不必戴 Hearing aid Now, because of the advancement of hearing aid technology and the improvement of personal quality of life, the effect of hearing aids is better for mild hearing impairment because of the mild inner ear disease, while the effect of severe hearing impairment is worse due to severe deterioration.Now the standard threshold for government subsidies for adult hearing aids is set at 55 decibels once every three years.
With the rapid development of science and technology, hearing aids are like computers. Through the re-upgrade of the chip, not only the effect of power saving but also the function is strengthened, making hearing aids more and more humanized and able to meet the needs of various hearing impairments.
The following is a brief introduction:
First, the open ventilation design improves the traditional uncomfortable feeling of plugging the ears. In the past, the sound always has a sense of distance, and now it can truly reproduce the original sound.
Second, the appearance of hearing aids made in China is getting smaller and smaller, and they are as light as a bean. Whether it is oneself or others, almost everyone forgets its existence. www.jhhearingaids.com
Third, binaural hearing aids are no longer independent operations, but just like our brains will communicate with each other and exchange information, choosing the most advantageous sound amplification, so that the disturbing noise no longer affects communication.
Fourth, with Bluetooth function, hearing aids have evolved from hearing aids to wireless communication interfaces!Connecting individuals to the vast world, such as mobile phones, TVs, MP3s, computers, navigation systems, etc., can transmit messages wirelessly, making users’ lives more exciting and enriching.
