45CC is a a flexible platform for dual-channel testing
of headphones and headsets. It can be configured with
microphones, IEC 60318-1 ear simulators and ITU-T P.51
mouth simulator. It can be adjusted very precisely to
support different headphone/headset designs and sizes
for high accuracy and repeatability. It is well suited for
research and development, quality control and production
line testing

45CB is deigned for standardized, binaural testing of passive
and active earmuffs and earplugs. Besides a robust
design made for field testing and high sound pressure
levels (blasts), it has a very high self-insertion loss, body
temperature regulated ear-canals with silicone lining and
a huge pinna surround – all to provide the most realistic
and repeatable fit.
45CB directly handles sound pressure levels up to 169 dB
and, indirectly (using comparision methods), levels up to
190 dB. It has a self insertion-loss better than 65 dB.
The modified IEC 60318-4 ear simulator with a ?” microphone
extends the frequency range as required by the
standard. The 14-mm long ear canal extension is designed
to let you also test all types of ear plugs.
The silicone-rubber lining of the extension enables leakage-free
mounting of both foam plugs and customized
molded types. The silicone-rubber lining of the plates
ensures leakage-free mounting, as well as high repeatability
and reliability
45CB設計用于被動語態的標準化雙耳測試。
積極的耳罩和耳塞。除了強壯
設計用于現場測試和高聲壓
水平（爆炸），它有很高的自我插入損shi，身體
帶有硅膠襯里和
巨大的耳廓環繞——所有這些都能提供真實的
可重復配合。
45CB直接處理高達169分貝的聲壓級
間接地（使用比較方法），達到
190分貝。它有一個比65分貝更好的自我插入損耗。
改進的帶1/4”麥克風的IEC 60318-4耳朵模擬器
根據需要擴展頻率范圍
標準。設計了14 mm長的耳道延長段。
讓你也測試所有類型的耳塞。
延長件的硅橡膠襯里可實現無泄漏
泡沫插頭的安裝和定制
模塑類型。板的硅橡膠襯里
確保無泄漏安裝以及高重復性
可靠性
