摘　　要：目的:研制一种新型抗强噪声通信头戴,在强噪声环境下既保证工作人员间的通话,又保护其听力。方法:利用压电陶瓷材料换能原理,将送、受话器集成一体,在护耳器中加入耳骨控耳塞,组成抗强噪声通信头戴。结果:新型抗强噪声通信头戴的多种耳塞接口可与不同型号的对讲机相连,满足机场外场等强噪声环境下工作人员间互相通话的需求。结论:新型抗强噪声通信头戴可以在隔离噪声的同时实现强噪声下的无线通信。Objective To develop a new type of anti-noise earphone to facilitate the communication between the staffs in strong noise environment and to protect their hearing. Methods Piezoelectric ceramic materials transducing energy were used to make the earphone, which integrated a microphone, a receiver and ear-bone control earplugs in earmuffs. Results The earphone had the earplug interface compatible with multi types of interphones, and could meet the requirements for the communication in strong noise environment. Conclusion The earphone realizes wireless communication in strong noise environment with the noise isolated.
