WebbStokes's law of sound attenuation is a formula for the attenuation of sound in a Newtonian fluid, such as water or air, due to the fluid's viscosity.It states that the amplitude of a plane wave decreases exponentially with distance traveled, at a rate given by = where is the dynamic viscosity coefficient of the fluid, is the sound's angular frequency, is the fluid … Webb声音是由物体振动产生的。 声音的传播需要 介质 ,它可在 气体 、 液体 和 固体 中传播,但 真空 不能传声。 声音在不同物质中的传播速度也是不同的,一般在固体中传播的速度最快,液体次之,在气体中传播得最慢。 并且,在气体中传播的速度还与气体的温度和压强有关。 正常情況下,聲速約等於331+0.6*攝氏溫度 m/s,室溫15攝氏度時聲速約340 m/s, …
