文| 子鱼 编辑| 贰沐 子鱼 《声学基础》中对于声强(Sound intensity)的定义是: 通过垂直于声传播方向的单位面积上的平均声能量流,也叫平均声能量流密度。我们平时做声学测试最常用的是麦克风测声压,那么为什…
Sound intensity level is not the same as intensity. Because β is defined in terms of a ratio, it is a unitless quantity telling you the level of the sound relative to a fixed standard (10−12 W/m2, in this case). The units of decibels (dB) are used to indicate this ratio is ...

探索声学世界:什么是声强(Sound Intensity)及其重要性? 在声学研究的深处,声强(Sound Intensity)是理解声音能量传输的关键参数。它被定义为垂直于声波传播方向的单位面积上,平均声能量流的密度。在《声学基础》中,这一概念揭示了声音能量的动态特性,超越了声压测量的局限性。为何声强不可或缺?...
The sound intensity is the sound power transmission through a surface (W/m2) - a vector quantity with direction through a surface. I = N / A (1) where I = sound intensity (W/m2) N = sound power through surface area (W) A = surface area (m2) Sound Intensity Level The dynamic...
声强(Sound intensity)是衡量声音在单位面积上平均声能量流的物理量。它能够提供比声压更全面的声源描述,尤其在能量和功率的考虑上。声强的测量与声压测试相辅相成,共同帮助我们理解声源特性和声场条件。为何在声学测试中需要声强?传统上,声压能够提供声音振幅的信息,但其局限性在于无法完全反映声源特性...

The meaning of SOUND-INTENSITY LEVEL is the relative sound intensity at any point in a sound field as compared with a specified standard intensity that is usually expressed in decibels above or below the standard.
