把以下文章翻译成英语,机器翻译勿扰
Sound is a mechanical disturbance of a wave nature that propagates through any elastic medium at a speed characteristic of that medium. When detected by the human ear, the presence of sound waves is often described by the subjective attribute of loudness, and this quality is usually quantified by averaging over a range of people (see section 3.1.3). Loudness is related to the amplitude of movement in the transmitting medium next to the eardrum.
Sound may be assessed after measurement of an appropriate physical quantity that varies about an equilibrium position as the sound wave or vibration passes the measuring point. Sound pressure
is the macroscopic physical quantity of most interest in fluids and gases. It depends on the amplitude of the disturbance in a material and most adequately represents the effect of acoustic waves on human response. Figure 2.1 illustrates how an acoustic pressure disturbance might vary about the ambient value for a typical sound wave. Atmospheric pressure is taken as the base line for airborne sound propagation.

声音是一种自然波的机械振动,通过弹性介质传播,速度取决于由该介质的特性.用人耳探测的话,体现为主观判断其音量大小,该特质通常由一群人的判断取平均值得出（见图3.1.3）.音量取决于声音在接近耳鼓的介质中传播时的振幅.声波或则叫震动通过测量点时会有一个平衡位置,声音的理特质近似地围绕着它上下波动,通过测量波动可以评估出声音大小.
声压表现为声音在液体或气体中的宏观物理特性,它取决于在某种材料中的振幅大小,充分代表声波在人类反应中的效果.表2.1解释了声波振动怎样围绕该特定声波的数值波动的.普遍认为,大气压力下的测得的声压是声音传播的参照线.
