How in-ear hearing aids work

In-ear hearing aidAccording to its shape characteristics can be specifically divided into: ear cavity type (English abbreviation ITE), ear canal type (English abbreviation ITC or CC), invisible deep ear canal type (English abbreviation CIC). However, since they are all worn in the ear, they are also referred to as in-ear type hearing aids.

  In-ear hearing aidFeatures: suitable for personal ears; easy to wear or remove hearing aids; make full use of the sound collection function of the outer ear; wear comfortable; less unobtrusive; can use the phone in the normal way: you can wear it while you sleep; In-ear hearing aids can be tailored to your hearing needs.

In-the-ear hearing aid principle

 In-ear hearing aidIt may be one of the most convenient and comfortable hearing aids. More importantly: the effect it can achieve on the sound can really enhance the user’s ability to listen. When we communicate with people, the biggest problem is not to hear, but to hear the sound, but we can’t understand the meaning. We often think that a word contains only one tone. In fact, each word is composed of several different tones. Now, take the word “three” as an example: “s” in the SAN sound is a high-frequency sound. If you hear the sound of “S”, you know that the word you hear is “three”. It is not “an”. Therefore, the high-frequency sound contained in the sound is the key to our understanding. The energy contained in the speech, 60% is concentrated below 500 (low frequency), that is, on the final (such as AN, EN, IA•••); 35% energy is concentrated between 500-1000 (Medium frequency); the little energy left is present in the high-frequency sounds that are closely related to speech. Usually, this characteristic of speech does not pose a problem for a person with normal hearing, but not for a person with hearing impairment. When the hearing loss mainly occurs in the high frequency band, the problem caused by the high frequency speech is very weak, so the problem is more complicated. None of the hearing aids can restore the damaged hearing system to normal.

  助听器只是把声音扩大,使你易于听取。耳内型助听器与一般助听器不同之处,即在于:耳内型助听器是在一个较有利的焦点上–耳道口,接受声音,因此能达到更有效的扩音效果。我们外耳,能把能量微弱的高频率语音,集中在耳道附近,以加强这些极其重要的声音。当助听器戴在耳朵外部时,需有一条较长的管子与耳部相连,这条管子会产生共振作用。共振的结果,往往使中频率的声音不自然地增强,增强后的中频率声音,会很容易遮蔽住音量微弱的高频率声音。相形之下耳内型助听器,只需用极短的管子,所以可有效的减少这种遮蔽的作用。与其他型助听器比较,耳内型助听器的另一项优点是麦克风的位置。通常麦克风把语音与环境噪音一起传送到扩大器。而环境中多数的噪音是以低频率音为主的。如果麦克风同时接收了低频率的噪音与重要的高频率的语音,那么音量强的噪音就会遮盖住音量弱的语音。耳内型助听器,其麦克风的位置设计在高频率声音最强的焦点–耳道口上,即可去除高频率语音被遮蔽的缺点。耳内型助听器还有许多显著的优点。它在外观上较不惹人注目,同时,使用者可从事于各种活动,不受到行动上限制。

The above advantages of the in-ear type hearing aid are extremely close to their appearance. The smaller the shape, the more obvious the above advantages. Therefore, the invisible deep ear canal hearing aid is the best, followed by the ear canal type hearing aid, and again the in-ear type hearing aid.
