Zusammenfassung:A pilot communication system employs a transducer array of individual spaced apart speakers and/or microphones for deployment within the cockpit. A signal processing circuit interfaces with the transducer array and also with the aircraft avionics communication system, and selectively applies different time delays to the individual speakers and/or microphones to create in the array an acoustic beam having steerable coverage within the acoustic space of the cockpit. By adjusting the time delays the signal processing circuit directs and focuses sound from the speakers to the pilot and similarly focuses the microphones on the pilot's mouth. In this way the pilots can communicate with each other and with air traffic control without the need to wear headsets. The system also significantly reduces flight deck warnings from being introduced into the cabin environment. 驾驶员通信系统采用单独的间隔开的扬声器和/或麦克风的换能器阵列,以用于部署在驾驶舱内。信号处理电路与换能器阵列并且也与飞机航空电子通信系统对接,并且选择性地对单独的扬声器和/或麦克风应用不同的时间延迟,以在阵列中创建在驾驶舱的声学空间内具有可引导的覆盖范围的声束。通过调整时间延迟,信号处理电路将声音从
