一、研究飞机座舱声学的重要性飞机在飞行中,由于上升、下降、转弯、气流波动等一系列的机械运动,已经给乘员造成极不舒适的感觉,若再伴以过大的舱内噪声就会使人们更感烦躁,甚至难以忍受.国外曾就飞机座舱环境的工作空间、压力、温度、前后及上下运动、烟味和噪声等因素对人的影响进行了多方面的测试.结果表明,舱内噪声被认为是第二重要的因素(见图1、图2).但是,直至现在,不少论述座舱环 I. The Importance of Studying Aircraft Cockpit Acoustics A series of mechanical motions of aircraft in flight due to ascent, descent, turning, air flow fluctuation and the like have given the occupants a very uncomfortable feeling. If combined with excessive cabin noise It will make people feel more irritable or even unbearable.External foreign cockpit environment has been on the working space, pressure, temperature, before and after and up and down movement, smoke and noise and other factors on the human impact of a wide range of tests.The results show , Cabin noise is considered to be the second most important factor (see Figure 1, Figure 2) However, until now, a lot of discussion cockpit ring
