Different Type Of Hearing aids 不同类型助听器

Open ear hearing aids prevent the over amplification of low frequencies.开放式助听器，防止对低频放大。 This is the perfect hearing aid for those with high frequency hearing loss.这是高频听力损失的完美助听器。 The technology inside this hearing aid is state of the art. ，内部的助听器技术是先进的。 It provides precise amplification for each hearing loss, without the annoying squealing (feedback).它为每个听力损失的确切放大，没有烦人的尖叫（反馈）。 This ultra-small behind-the-ear hearing aid, coupled to a thin -tube and a small ear bud makes this the hearing aid of choice for comfort.这个小幕后助听器，再加以细管和一个小耳塞使这种选择舒适助听器超。 Since it is virtually invisible it is also cosmetically appealing.因为它是几乎看不见它也是美化妆品的吸引力。
A hearing aid is an instrument that brings sound more effectively to the listener's ear, helping hearing impaired people hear sounds better.助听器是一种手段，使声音更有效地向听众的耳朵，帮助听力障碍的人听到的声音更好。 Early devices were passive, and attempted to gather sound energy and direct it to the ear.早期的装置是被动的，并企图收集无害的能源和直接到耳朵。 A funnel-like amplification cone called an “ear trumpet” or “ear horn” was one of the first such devices.Today, the most common hearing instrument is the electroacoustic aid, a small electronic device that typically fits in or behind the wearer's ear.漏斗状放大锥称为“助听器”或“耳角”是第一个这样的devices.Today，最常见的助听器之一是电声援助，一个小型电子设备，或后面通常佩戴者的耳朵适合。

Types of hearing aids 助听器的种类
There are many types of hearing aids (also known as hearing instruments), which vary in size, power and circuitry.有许多类型的助听器（也称为听力设备），它在尺寸，功耗和电路有所不同。 Among the different sizes and models are:是在不同的规格型号：

• Body worn aids 身体佩戴助听器

This was the first type of hearing aid, and thanks to developments in technology they are now rarely used.这是第一种助听器，并在技术，现在很少使用的事态发展表示感谢。 These aids consist of a case containing the components of amplification and an ear mold connected to the case by a cord.这些援助包括一个载有放大的组成部分案件一耳模通过连接线连接到案件。 The case is about the size of a pack of playing cards and is worn in the pocket or on a belt.案件是关于一个扑克牌大小，穿在口袋或腰带上。 Because of their large size, body worn aids are capable of large amounts of amplification and were once used for profound hearing losses.由于其规模大，身体佩戴助听器是大量的放大能力，是一次深刻的听力损失73。

• Behind the ear aids (BTE) 耳后助听器（耳背式）

BTE aids have a small plastic case that fits behind the ear and provides sound to the ear via air conduction of sound through a small length of tubing, or electically with a wire and miniature speaker placed in the ear canal.耳背式助听器有一个小塑料外壳的背后，适合耳通过空气和声音传导提供声音的耳朵通过管，或有电线和微型扬声器在耳道放在electically小的长度。 The delivery of sound to the ear is usually through an earmold that is custom made, or other pliable fixture that contours to the individuals ear.的声音传递到耳朵通常是通过一个耳模是习惯了，或其他柔软夹具，为个人耳朵轮廓。 BTEs can be used for mild to profound hearing losses and are especially useful for children because of their durability and ability to connect to assistive listening devices such as classroom FM systems. BTEs可用于轻度至深度听力损失，特别是由于其耐用性和连接的能力，如教室调频系统，辅助儿童有益的窃听器。 Their colors range from very inconspicuous skin tones for adults to bright colors and optional decorations for children.它们的颜色范围从明亮的颜色和装饰为儿童选购成人很不起眼的肤色。

• In the ear aids (ITE) 在耳艾滋病（资讯科技教育）

These devices fit in the outer ear bowl (called the concha); they are sometimes visible when standing face to face with someone.这些器件适合在外耳碗（称为鼻甲），他们有时可见站立时面对面的人。 ITE hearing aids are custom made to fit each individual's ear.资讯科技教育助听器定制以适应每个人的耳朵。 They can be used in mild to some severe hearing losses.它们可用于轻度至重度听力损失一些。 Feedback, a squealing/whistling caused by sound leaking out of the aid and being amplified again, may be a problem for severe hearing losses.反馈，尖叫声/吹口哨造成泄漏出的援助声再次被放大，可能有严重听力损失的问题。 Some modern circuits are able to provide feedback regulation or cancellation to assist with this.And so on are given below:一些现代电路能够提供反馈调节或取消与this.And协助等情况如下：

Receiver In the ear aids (RITE), In the canal (ITC),  mini canal (MIC) and completely in the canal aids (CIC), Open-fit devices, Bone Anchored Hearing Aids (BAHA), &Eyeglass aids,接收机在耳艾滋病（成年礼），在运河（国贸中心），小管（MIC）和艾滋病在运河（CIC）的，开放式的设备完全适应，骨锚式助听器（巴哈伊），＆镜片艾滋病，

• Wireless 无线

Recentent  hearing aids include wireless hearing aids. Recentent助听器包括无线助听器。 One hearing aid can transmit to the other side so that pressing one aid's program button simultaneously changes the other aid and both aids change background settings simultaneously.一个助听器可以传送到另一边，使一个紧迫援助的计划按钮，同时改变了其他援助和艾滋病变化的背景下都同时设置。 FM listening systems are now emerging with wireless receivers integrated with the use of hearing aids.调频听系统正在出现的与助听器使用集成的无线接收器。 A separate wireless microphone can be given to a partner to wear in a restaurant, in the car, during leasure time, in the shopping mall, at lectures, or during religious services.一个单独的无线话筒，可以给合作伙伴穿在餐厅，在车里，在娱乐旅行的时间，在商场，在讲座，或在宗教服务。

• Directional microphones 定向麦克风

Directional microphones are currently – after FM systems, see below – the best way to improve the signal to noise ratio, and thus, improve speech clarity in noise for the wearer.目前定向麦克风 - 调频系统后，低于 - 看到的最好办法，以改善信噪比的信号，因此，改善噪音穿着者讲话清晰。

• Telecoil Telecoil

Telecoils (T-coils) allow different sound sources to be directly connected to the hearing aid, improving sound quality and allowing the hearing aid wearer to easily perceive the intended signal regardless of background noise. Telecoils（翻译线圈）允许不同的声音来源，直接连接到助听器，提高声音质量，并允许助听器佩戴者轻易地感知拟信号，无论其背景噪音。 They can be used with telephones, FM systems, induction loop systems and public address systems.它们可用于电话，调频系统，感应系统和公共广播系统。 Such hearing loop systems are widely used in public places such as churches, shops and railway stations in the UK and some Scandinavian countries.这样的听证会闭环系统被广泛用于如教堂，商店和英国火车站和一些北欧国家的公共场所 。
