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(shè)計(jì)用于被動語態(tài)的標(biāo)準(zhǔn)化雙耳測試。

積極的耳罩和耳塞。除了強(qiáng)壯

設(shè)計(jì)用于現(xiàn)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(huán)繞——所有這些都能提供真實(shí)的

可重復(fù)配合。

45CB直接處理高達(dá)169分貝的聲壓級

間接地（使用比較方法），達(dá)到

190分貝。它有一個(gè)比65分貝更好的自我插入損耗。
