traffic noise
It mainly refers to the noise emitted by motor vehicles, aircraft, trains, ships and other vehicles during operation.The noise source of these noises is mobile, and the interference range is large.
Industrial noise
It mainly refers to the noise generated in industrial production.Mainly from machines and high-speed running equipment.
Building construction
It mainly refers to the noise generated at the construction site.During the construction, a large number of power machines are used, such as excavation, hole drilling, mixing, and frequent transportation of materials and components, thus generating a lot of noise.
civil life
It mainly refers to the noise generated by people in various social activities such as business transactions, sports competitions, parades and gatherings, and entertainment venues, as well as the noise of various household appliances such as radio recorders, televisions, and washing machines. Such noise is generally below 80 decibels.For example, the noise of washing machines and sewing machines is 50-80 decibels, the noise of electric fans is 30-65 decibels, and the noise of air conditioners and televisions is 70 decibels.[2]

Subjective Sensibility
The impact of acoustic environment is a kind of sensory public nuisance, because it depends not only on the intensity of noise, but also on the behavior of the affected people at that time, and is related to their own physiological (feeling) and psychological (feeling) factors.Different people, or the same person in different behavior states, will have different responses to the same noise.
Locality and dispersion
Localization andDispersityIn the following two aspects: First, any environmental noise source can only affect a certain range due to factors such as distance divergence and attenuation, and people beyond a certain distance will not be affected by the sound source;Secondly, the noise sources of the environment are scattered. It can be considered that the noise sources are ubiquitous, and people can be affected by the noise in different places.
tentative
Temporary impact on the acoustic environment: once the noise source stops producing sound, the surrounding acoustic environment can be restored to its original state, and the impact can be eliminated immediately.[3]
noise control

edit
In order to prevent the harm of environmental noise pollutionPhonologistMa DayouProfessor Zeng summarized and studied the existing hazards and standards of various kinds of noise at home and abroad, and put forward three suggestions:
Hearing and physical health
The allowable noise value is 75~90 decibels.
Guarantee conversation and communication
The allowable value of environmental noise is 45~60 decibels.
sleep
It is recommended to be 35~50 decibels.
Chinese psychologists believe that in addition to human factors, economic and technical feasibility must also be taken into account to control the noise environment.Adequate noise control must consider the whole system composed of noise source, transmission path and receiver.Noise control measures can be taken for the above three parts or any of them.[4]
control measures

edit
Control noise source
To reduce the noise of the noise source, the industry and transportation industry can choose low-noise production equipment and improve the production process, or change the movement mode of the noise source (such as dampingVibration isolationAnd other measures to reduce the vibration of solid sound generator).
Blocking noise propagation
Reduce noise in the way of sound transmission, control the spread of noise, and changesound sourceThe transmission channels of emitted noise, such as sound absorption, sound insulation, sound barrier, vibration isolation and other measures, as well as reasonable planning of urban and architectural layout.
Reduce noise at human ear
When the noise protection of the recipient or the recipient organ is unable to take measures on the sound source and transmission route, or the acoustic measures taken still cannot achieve the expected effect, it is necessary to take protective measures for the recipient or the recipient organ. For example, workers exposed to long-term occupational noise can wear ear plugsEarmuffOr helmet, etcEar protector。
Noise controlAlthough technically mature, due to the large scale of modern industry and transportation industry, there are many enterprises and places that need to adopt noise control. Therefore, in terms of noise prevention, a comprehensive balance must be made in terms of technology, economy and effect.Of course, specific problems should be analyzed specifically.The noise intensity shall be low outside the control room, design room, workshop or the place where the staff work for a long time;Few people go to workshops or open places in the warehouse, so it is OK to have a little higher noise.In short, there should be some differences in the treatment of noise at different times, places, natures and durations.[5]
