定製式助聽器

優點：

1、相對耳背機，定製式助聽器種類比較小，可以擁有很好的隱蔽性，美觀大方。因為遍及採用高分子抗過敏材料，舒適便利。

2、可以開通氣孔，以避免堵耳效應。

3、因為沒有耳管，所以它可以避免中頻部分的共振效應。

現在干流的助聽器種類是耳背式助聽器及定製式助聽器。

耳背式助聽器分為一般耳背式（BTE）和開放式耳背助聽器。

定製式助聽器可分為耳內式助聽器（又稱全耳甲腔式助聽器，ITE）、耳道式助聽器（ITC）、深耳道式助聽器（CIC）和隱形助聽器（IIC）。

假如按功率大小來分類，我們能够將助聽器分為小功率助聽器、中功率助聽器和大功率助聽器。
假如按作业原理來分類，我們能够將助聽器分為模擬助聽器、模擬手動編程助聽器和全數字助聽器。

客觀聽力檢查主要包含聲導抗檢查，耳聲發射檢查和聽性腦幹反應測聽。

1、聲導抗和鼓室導抗測聽。聲導抗檢查是客觀測試中耳傳音系統和腦幹聽覺通路功用的办法。鼓室功用曲線以A 、B 、C三個大寫字母分別代表正常型、平坦型、鼓室負壓型，不同的波形反應的意義是纷歧樣的。

2、耳聲發射檢測：耳聲發射是一種客觀的聽功用檢查手法，依賴於耳蝸整體功用的完整，與耳蝸外毛細胞的功用亲近相關。通過耳聲發射檢查我們能够了解內耳外毛細胞的功用狀態，以此來判斷導致耳聾發生的部位，臨床上常用於重生兒和嬰幼兒的聽力篩查。

3、聽性腦幹反應測聽：腦幹聽覺誘發電位是一種比較客觀的聽力及腦幹功用檢查技術。外界給予聲音影响後，從腦部描記得聽覺神經同路的生物電變化。通過各種分析，能够反映出聽神經組織的生理過程和病理現象。這種办法能够用於前期發現聽損傷或聽覺傳導通路的器質性病變，能够協助推斷聽力障礙的性質及聽功用異常定位。

1、音叉試驗。音叉試驗是聽力檢查最常用的底子方法。用於开端断定耳聾，但不能判斷聽力損失程度。音叉依頻率不同，分為C128、C256、C512、C1024、C2048，分別發出不同聲音。順便引申一下，最早的音叉竟然是以餐叉為原型而設計的，是不是感覺很奇特？

2、純音測聽：用於判斷有無聽覺障礙，估計聽覺損害程度。是一種最常用的主觀測聽法。純音聽力結果以純音聽閾圖呈現，橫坐標為頻率（Hz），縱坐標為聲級（dB）。檢查完畢後純音聽力結果為兩條曲線，即氣導和骨導，根據兩者的關係判斷聽力損傷的類型和程度。

3、行為測聽：行為測聽首要適應於小兒。這種測試需求孩子對聲音產生反應並通過某種行為表現出來，如將頭轉向聲源或做出某種動作，通過這些反應檢查者判斷小兒的聽閾，測試結果可表明聽力損失的程度、性質和聽力損失對孩子沟通才能的影響。由於這種測試需求孩子的主動合作，因而孩子的年齡和成熟程度決定著檢測結果的可靠性。

The dependence of Chinese textile industry to resource rate is higher, the sources of energy is used up bigger, at present the industry is facing many difficulty in the energy-saving job that decrease a platoon: For instance the energy-saving investment that decrease a platoon is not worth most spin enterprise, advanced tooling is used rate is lower, the pressure of capital, technology is faced in real work, the industry is energy-saving a bit of the job that decrease a platoon cannot lax. And the reality in facing the job is painful, no matter be guild or enterprise, trying hard actively, shift all sorts of resource, advance effectively what promote the energy-saving work that decrease a platoon, to “ 925 ” end in order to realize the ” of relevant “ good target of the energy-saving task that decrease a platoon.

Where be hard?

Spin industry carries out the energy-saving working face that decrease a platoon to facing the difficulty of a lot of reality, among them the biggest restrict come from at capital and technology. In the meantime, the enterprise still has bigger difference to can developing the acknowledge of importance continuously.

Energy-saving decreasing a platoon is project of a system, need holds job each force that square force leaves socially even undertakes jointly. Will look from inside real work, spin industry is in energy-saving the propulsion that decreases a platoon has encountered not little difficulty in the process, and this among them most crucial factor is capital and technology restrict.

Energy-saving the thing of a very short time of the blame that decrease a platoon, throw ” of this “ career to need the investment with much business, be prolonged even. Textile regards a country as property of most principal the people's livelihood, its of 90% above is medium and small businesses, this shows the medium and small businesses that holds industry great majority wants to carry out energy-saving decreasing a platoon is not an easy thing, because be in its process, the enterprise should consider can obtain the relevant technology, cost that pursues a technology how to much want, devoted capital whether close to wait for a problem in later period operation. Even if the big company of dress of a few spin, also must consider these issues.
