非线性耳塞的结构设计与工作原理

WORKING PRINCIPLE AND STRUCTURE DESIGN OF NONLINEAR EARPLUG

文章阐明了一种非线性耳塞的结构设计与工作原理。这种耳塞按炮兵使用要求进行设计 ,在高强度脉冲噪声的作用下 ,有很高的隔声量可以保护听力 ;在低声级环境中 ,其隔音量又足够低 ,可以保证能接收到一些有用的声信号。

A type of nonlinear earplug and its working principle and structure design are introduced. This kind of earplug has high sound insulation ability and is designed to protect auditory from intensive impulse artillery noise. In the environment with lower noise level, the earplug will decrease its sound insulation factor accordingly to ensure the useful voice can be heard.
