| 传播过程 | propagation process Process by which a disturbance at one point is propagated to another point more remote from the source with no net transport of the material of the medium itself; examples include the motion of electromagnetic waves, sound waves, hydrodynamic waves in liquids, and vibration waves in solids (从某一点传播到另一个点的传输过程；如在固体中传播的电磁波、声波、水波和振动波等。) |
| 声传播 | sound propagation The travelling of acoustic waves in the atmosphere with a speed independent of their amplitude. The speed only depends on the acoustic medium and is proportional to the square route of the absolute temperature for any given medium (大气中以一定速度传输的声波与它的振幅无关。速度只取决于声中介，与任何介质的绝对温度的平方路线成正比。) |
| 声音传播 | sound transmission Passage of a sound wave through a medium or series of media (通过媒介或系列媒体传递的声波。) |
| 大众传播媒体 | mass media The means of communication that reach large numbers of people, such as television, newspapers, magazines and radio (可延伸至大量人群的通讯传播方式，如电视，报纸，杂志和无线电广播。) |
| 广播播送区 | service area |
| 广播节目 | radio programme A performance or production transmitted in sound signals with electromagnetic waves (通过电磁波传输声音信号的节目或表演。) |
| 空气传播噪声 | airborne noise Noise caused by the movement of large volumes of air and the use of high-pressure air (大量气体移动或使用高压气体所产生的噪音) |
