| 冲击性噪音 | impulsive noise Noise characterized by transient short-duration disturbances distributed essentially uniformly over the useful passband of a transmission system (经由传达系统所产生的一致性且持续时间短的噪音。) |
| 动物噪音 | animal noise Noise caused by animals such as dogs kept in kennels or in private homes as pets (动物比如在宠物园或者家里被当作宠物饲养的狗，所发出的噪音。) |
| 商业噪音 | commercial noise Noise emitted from commercial activities (商业活动中发出的噪音。) |
| 噪音对的健康影响 | health effect of noise Noise consequences on human health consist in loss of hearing and psychological effects (导致人类听力损失与心理影响的噪音影响。) |
| 噪音干扰 | noise disturbance Noise interferes with communication and interferes with thought processes. Noise interferes with sleep, it causes anger and frustration, and has been implicated as a contributor to various psychological and physiological problems. Noise detracts from the quality of life and the environment (噪声影响沟通和思维过程。噪声妨碍睡眠，它会导致愤怒和失望，并已牵涉作为各种心理和生理问题的促成因素。噪音有损于生活和环境质量。) |
| 噪音控制 | noise control The process to control the audible sound to an acceptable level (控制发声声音到可接受水平的过程。) |
| 噪音级指"雪花"干扰的程度 | snow level |
| 城市噪音 | urban noise Noise emitted from various sources in an urban environment (城市环境中各种来源所释放的噪声。) |
| 声音 | sound Auditory sensation produced by the oscillations, stress, pressure, particle displacement, and particle velocity in a medium with internal forces; pressure variation that the human ear can detect (通过媒介在内力的作用下，由震动、压力、压强、颗粒移置和质点速度所产生的听觉的震荡，人耳可检测到的压力的变化。) |
| 声音传播 | sound transmission Passage of a sound wave through a medium or series of media (通过媒介或系列媒体传递的声波。) |
| 声音排入 | sound immission The introduction in the environment of noise deriving from various sources that can be grouped in: transportation activities, industrial activities and daily normal activities (在噪音环境中各种噪音源的引入，可以分为：交通运输活动，工业活动和日常生活的正常活动。) |
| 声音测量 | sound measurement Because of the large variations in sound magnitudes, and because the human hearing sensation seems to vary in a logarithmic way, logarithms are used in measurement of sound. The sound pressure level is given in decibels (dB) (由于声音的变化幅度大，且人耳的感觉似乎是以对数的方式改变,对数被用来测量声音，声压大小以分贝的方式给出。) |
| 家庭噪音 | domestic noise Noise caused by domestic facilities and activities (由家庭设施和活动造成的噪音。) |
| 工业噪音 | industrial noise Noise produced by industrial plants activities (工业设备操作所产生的噪音。) |
| 建筑噪音 | construction noise Noise resulting from construction activities such as site preparation, site clearance, demolition of existing buildings, piling, concreting, erection of structures, etc. (来自建筑活动的噪音，例如场地的准备、清理、既有建筑物的拆除、打桩、灌浆、及建物建造过程等。) |
| 消音器 | silencer Any device designed to reduce noise, especially the device in the exhaust system of a motor vehicle (用以降低噪声的设备，尤其指汽车的排气系统装置。) |
| 爆音 | sonic boom A noise caused by a shock wave that emanates from an aircraft or other object traveling at or above sonic velocity (由冲击波从飞机或其他高于声速行的物体而产生的噪音。) |
| 环境噪音 | environmental noise The sound and the characteristics of sounds from all sources in the surrounding environment (来自周围环境的污染源的声音和特性。) |
| 背景噪音 | background noise Noise coming from source other than the noise source being monitored (来自非监测渠道的噪音。) |
| 超低频音 | infrasound Vibrations of the air at frequencies too low to be perceived as sound by the human ear, below about 15 hertz (低于15赫兹，人耳无法识别的空气振动频率。) |
| 间歇性噪音 | intermittent noise Noise occurring at regular or irregular intervals (在规则或不规则时间间歇所产生的噪音。) |
| 隔音 | soundproofing Reducing or eliminating reverberation in a room by placing sound-absorbing materials on the walls and ceiling (通过放置吸音的墙壁和天花板材料减少或消除房间的回响。) |
| 隔音 | acoustic insulation The process of preventing the transmission of sound by surrounding with a nonconducting material (通过在外面报上绝缘物质以阻止声音传播的过程。) |
| 隔音屏障 | noise barrier Barriers for reducing the propagation of sound: they are widely used in industry and alongside roads and railways to shield receivers from noise sources. Barriers will not reduce the noise on the receivers side, but will increase it, unless the barrier is also covered in absorbing material (为减少声音传播的屏障：它们是广泛应用于工业和公路、铁路来屏蔽噪声源的接收器。屏障将不会减少接收端的噪声，但会增加，除非屏障也覆盖了吸波材料。) |
| 隔音材料 | sound insulation material Material used to reduce the transmission of sound to or from a body, device, room, etc. (用于降低声音从音源到特定装置、设备和房间等的传输的材料。) |
| 音乐 | music The artistic organization of sounds or tones that expresses ideas and emotions through the elements of rhythm, melody, harmony and tonal color (声音或音调通过节奏元素、旋律、和声和音色来表达思想和情感的艺术组织形式。) |
| 音量 | sound level The sound pressure level (in decibels) at a point in a sound field, averaged over the audible frequency range and over a time interval (声压大小(分贝)在声场上的一个点，平均发声频率范围和时间间隔超过1。) |
