关于噪声对语言通讯的干扰,已有不少文献报道。许多学者认为,噪声不仅引起人们情绪紧张、烦恼,而且干扰人的语言和工作。如空压机工作时,近距离几乎能压抑所有人的嗓音。舰船主机噪声可以引起艇员精神疲乏,注意力分散,降低艇员的工作效率。其中在无线电室的影响更为突出。经测定,舰艇在巡航速度时,舱内噪声为65～70dBA,如果全速航行,加之通风设备的工作,舱内噪声水平更高,给训练尤其是战时带来的影响是十分严重的。因此,必须制定一个切实可行的舰艇舱室噪声允许标准,采取必要的措施,保证艇员的正常工作。本文就噪声对无线电纯音信号干扰的影响,拟定出在几种特定的无线电纯音信号频率下无线电舱室环境噪声的允许水平。
There have been many reports on the interference of noise on language communication. Many scholars believe that noise not only causes people’s emotional stress and worry, but also disrupts people’s language and work. Such as air compressor work, close to almost suppress everyone’s voice. Shipboard hostage noise can cause mental fatigue, distracted, and reduce crew efficiency. One of the more prominent in the radio room. It has been determined that at cruising speed, the noise in the cabin is 65~70 dBA. If full speed voyage and ventilation work are performed, the noise level in the cabin will be higher, which will have a very serious impact on training especially in wartime. Therefore, it is necessary to formulate a practicable noise allowable standard for cabin cabins and take the necessary measures to ensure the normal work of the crew. In this paper, the effect of noise on the interference of radio pure tone signals is studied, and the allowable level of ambient noise of the radio cabin at several specific radio pure tone frequencies is developed.
