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设计用于被动语态的标准化双耳测试。

积极的耳罩和耳塞。除了强壮

设计用于现场测试和高声压

水平(爆炸),它有很高的自我插入损shi,身体

带有硅胶衬里和

巨大的耳廓环绕——所有这些都能提供真实的

可重复配合。

45CB直接处理高达169分贝的声压级

间接地(使用比较方法),达到

190分贝。它有一个比65分贝更好的自我插入损耗。

改进的带1/4”麦克风的IEC 60318-4耳朵模拟器

根据需要扩展频率范围

标准。设计了14 mm长的耳道延长段。

让你也测试所有类型的耳塞。
