Bone conduction hearing aid–Introduction of bone conduction hearing aid
In the user community of the ear tree, occasionally someone asks how to distinguish between a gas-guided hearing aid and a bone-guided hearing aid, and which kind of hearing aid is appropriate. Why is it “occasional” because most people may not even know the concepts of “air conduction” and “bone conduction”, let alone distinguish them. After hearing loss, everyone knows that either a hearing aid or a cochlear implant is used, but it is often overlooked that the hearing aid is actually classified.
However, this article is not a simple meaning for everyone to be a bone conduction hearing aid, but to stand in an objective and comprehensive perspective to talk about the advantages and disadvantages of bone conduction hearing aids. With the craze of smart devices, the concept of bone conduction has emerged in an endless stream, and bone conduction hearing aids have also become hot. But only the advantages are not limited, which will largely mislead the listener’s choice of hearing aids. The ear tree thinks it is wrong. Everything has its two sides, and realizing each side of it is the only way for things to survive and develop.
First, the type of common deafness:
In life experience, we often find it strange to use a tape recorder or a WeChat voice to listen to our voice. In addition to the distortion of electronic devices, there is one more important reason, that is, we usually listen to our own voice from “air+The bones are in two ways, and the recorded sound is only transmitted from the “air” to the ear.
There are three main types of deafness: conductive deafness, neurological deafness, and mixed deafness. The mixed deafness is the same as the first two. “The air conduction pathway is destroyed” is conductive deafness, such as the tympanic membrane is broken, the external auditory canal is blocked, and the middle ear is inflamed; “the inner ear hearing hair cell is reduced” and even the auditory nerve and auditory central fault are “neural deafness”. It is simple to understand that the external power cord that is similar in conductivity to an electric lamp is broken; the neurological deafness is similar to the filament of an electric lamp broken.
