聆康來(lái)簡(jiǎn)單告知你,聽(tīng)力計(jì)的類型根據(jù)純音聽(tīng)力計(jì)的功能與用途不通,分為以下五類型 :

一類診斷型

頻率范圍:125HZ-8KHZ(按1/3倍頻程排列);

AC大輸出:120dBHL;

BC大輸出:70dBHL;

具有氣導(dǎo)耳機(jī)和骨導(dǎo)耳機(jī)以及寬帶噪聲和窄帶噪聲;

有多種閾上功能測(cè)試;

雙通道;

設(shè)有多種輔助功能:配合言語(yǔ)測(cè)試用的輸入端接口,聽(tīng)力計(jì)的類型配合開放聲場(chǎng)用的功率放大器以及揚(yáng)聲器接口等;

供科研及使用。

二類診斷型

頻率范圍:125-8000HZ;

AC大輸出:110dBHL;

BC大輸出:70dBHL;

具有氣導(dǎo)耳機(jī)和骨導(dǎo)耳機(jī)以及寬帶噪聲和窄帶噪聲;

有部分閾上功能測(cè)試;

通常為雙通道;

設(shè)有些輔助功能:配合言語(yǔ)測(cè)試用的輸入端接口。

三類簡(jiǎn)單診斷型

頻率范圍:聽(tīng)力計(jì)的類型250-4000HZ;

AC大輸出:100dBHL;

BC大輸出:50dBHL;

具有氣導(dǎo)耳機(jī)和骨導(dǎo)耳機(jī)以及寬帶噪聲和窄帶噪聲。

四類篩查型

頻率范圍:500-2000HZ;

AC大輸出:70dBHL;

僅有氣導(dǎo);

衰減器為5dB檔。

五類骨導(dǎo)型

僅設(shè)骨導(dǎo)聽(tīng)力計(jì),無(wú)氣導(dǎo)。
