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。) | |||
