物体无规律性的振动所产生的杂乱无章,听起来不悦耳或不受人们欢迎,起干扰作用的声音称为噪音。声波造成的体内生理性损伤。声波能引起压力的变化,其强度决定于振幅、产生声音的力量和声波的分布。宇宙医学中噪声主要产生于飞机及宇宙火箭的推进装置。暴露于强噪声中,能引起听力损失及产生耳内某些部分的物理性损伤。在足够强度的声波中暴露足够的时间,能使对声音的分辨能力下降。听力丧失可由中耳、鼓膜及内耳司听觉的毛 The irregular, unpleasant or unpleasant sound produced by irregular vibration of an object is called noise. Sonic physiological damage caused by the body. Sound waves can cause pressure changes, the intensity depends on the amplitude, the power of sound and the distribution of sound waves. In cosmology, noise mainly comes from propulsion devices of aircraft and space rockets. Exposure to strong noise can cause hearing loss and physical damage to certain parts of the ear. Adequate time is exposed in sufficiently strong sound waves to reduce the resolution of the sound. Hearing loss by the middle ear, tympanic membrane and inner ear Secretary hair
