| 噪声测量 | noise measurement The process of quantitatively determining one or more properties of acoustic noise (定量测定噪声的一个或多个属性的过程。) |
| 噪声照射 | noise immission Immission in the environment of acoustic vibrations that negatively affect human beings, animals, plants or other objects (声音震动排入环境，对人类、动物、植物或其他物体造成负面影响。) |
| 噪声干扰，杂音电平 | noise level |
| 噪声监测 | noise monitoring The systematic deployment of monitoring equipment for the purpose of detecting or measuring quantitatively or qualitatively the presence, effect, or level of noise (为了定性定量检测和测量噪音的存在、影响或水平而系统部署的监测设备。) |
| 噪声等效温差 | noise equivalent delta temperature |
| 噪声类型 | noise type |
| 噪声级 | noise level Physical quantity of unwanted sound measured, usually expressed in decibels (有害声音物理量的测量，通常以分贝表示。) |
| 噪声防护 | noise protection Adoption of measures for controlling noise pollution, such as restriction of the emission of noise from industrial, commercial and domestic premises, from motor vehicles and aircrafts, the provision of noise barriers and buffer zones, the fitting of sound attenuation equipment, etc. (采用控制噪声污染的措施，如限制来自工业、商业、住宅楼宇和汽车、飞机排放的噪声，提供隔音屏障及缓冲区，采用适当的消声装置等。) |
| 噪声频谱 | noise spectrum The range of frequencies occurring in the noise emitted by a source (出现在同一来源发出的噪声的频率范围。) |
| 无噪声技术 | noise-free technology Sound is radiated both as air-borne and as structure-borne; most sources produce both, thus various noise attenuation principles must be employed. Measures include: the replacement of components with quieter parts and material; the enclosure of particularly noisy components; the selection of quieter types of fan; the replacement of noisy compressed-air nozzles with quieter types; the choice of quieter transmission and cooling systems (声音可同时作为空气传播和结构传播；大部分的传播来源同时产生，因而不同的噪音衰减原则须得到使用。措施包括：用消音零件和材料更换部件；隔绝特定的噪声部件；选择消音风扇；用消音类型更换噪音压缩空气喷嘴；选择消音传输和散热系统。) |
