聆康來簡單告知你，聽力計的類型根據(jù)純音聽力計的功能與用途不通，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)耳機和骨導(dǎo)耳機以及寬帶噪聲和窄帶噪聲；有多種閾上功能測試；雙通道；設(shè)有多種輔助功能:配合言語測試用的輸入端接口,聽力計的類型配合開放聲場用的功率放大器以及揚聲器接口等；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)耳機和骨導(dǎo)耳機以及寬帶噪聲和窄帶噪聲；有部分閾上功能測試；通常為雙通道；設(shè)有些輔助功能:配合言語測試用的輸入端接口。三類簡單診斷型頻率范圍：聽力計的類型250-4000HZ；AC大輸出：100dBHL；BC大輸出：50dBHL；具有氣導(dǎo)耳機和骨導(dǎo)耳機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)聽力計，無氣導(dǎo)。 <img anchorname="OLE_LINK3" class="anchorclass" style="max-width: 50%; background: url("/public/plugins/Ueditor/themes/default/images/anchor.gif") left center no-repeat scroll transparent; cursor: auto; display: inline-block; height: 16px !important; width: 15px !important;" alt="" /><img anchorname="OLE_LINK2" class="anchorclass" style="max-width: 50%; background: url("/public/plugins/Ueditor/themes/default/images/anchor.gif") left center no-repeat scroll transparent; cursor: auto; display: inline-block; height: 16px !important; width: 15px !important;" alt="" /><a href="https://www.linkind.top/" target="_blank" _href="https://www.linkind.top/" style="font-size: 24px;"><span style="font-size: 20px; font-family: 宋體; color: red; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">聆康聽力集團官網(wǎng)：<span style="font-size: 20px; font-family: Arial, sans-serif; color: red; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">www.linkind.top(<span style="font-size: 20px; font-family: 宋體; color: red; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">點擊跳轉(zhuǎn)<span style="font-size: 20px; font-family: Arial, sans-serif; color: red; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">)</a><img anchorname="OLE_LINK4" class="anchorclass" style="max-width: 50%; background: url("/public/plugins/Ueditor/themes/default/images/anchor.gif") left center no-repeat scroll transparent; cursor: auto; display: inline-block; height: 16px !important; width: 15px !important;" alt="" /><img anchorname="OLE_LINK5" class="anchorclass" style="max-width: 50%; background: url("/public/plugins/Ueditor/themes/default/images/anchor.gif") left center no-repeat scroll transparent; cursor: auto; display: inline-block; height: 16px !important; width: 15px !important;" alt="" /><div> </div>" />
