Study On Noise Collection And Influence Of Building Construction

With the rapid development of urbanization,high-rise buildings in cities are springing up like mushrooms.The inevitable impact of high-speed development is some negative effects.The more efficient and efficient construction operations are due to the widespread use of construction machinery,and the problem of construction noise also comes into being.Increasing construction noise determines the need for more efficient noise solutions.The relevant international organizations have clearly defined the emission control of construction noise.Relevant indicators such as limits,hearing loss and unsafe behavior are all related standards in noise control.The international regulations on construction noise have been relatively mature in 1990 s,and the relevant standards for noise exposure limit have been formulated.Countries all over the world have unique indicators for noise control,but the standards are not uniform.According to their own national conditions,the requirements of the WHO are further requested on the basis of their national conditions.Relevant departments in China began to recognize the negative effects of construction noise as early as 1982,and formulated relevant standards to control the emission of construction noise.This study takes the theory of occupational health as the starting point,takes the actual construction site as the focal point,takes the construction site staff as the research perspective,takes the reading Lake project as the spatial template,and takes the literature research,the on-site actual noise monitoring,the subjective investigation and the scientific experiment as the backing.The noise level of the construction site beyond the prescribed scope and the subjective feeling of the construction workers on the construction noise were calculated.A total of 26 noise maps of the construction site were produced through a large number of on-site noise monitoring,and the total time was 26.The time and space relationship between the noise exposure and the construction site were analyzed,and the noise files were compiled as the basic data to provide the basis for further research.Through the noise collection of the typical construction machinery at the construction site,the corresponding noise spectrum analysis is carried out,and the different sound characteristics of each noise are obtained,and the degree of influence of different kinds of noise on people is detected by the questionnaire.The survey of the influence of the construction site on the staff is conducted by means of a questionnaire survey.A total of 143 questionnaires were collected,excluding 135 of them.In this way,the operators’ perception of noise on the scene is determined,and the correlation between subjective feelings and work type and working years is analyzed,as well as the differences caused by the same type of work due to different types of work and years of work.The questionnaire involves the audiometric limit audiometry of the investigated personnel,and the difference between the workers of different jobs and working years is analyzed according to their subjective feelings and frequency domain limits.Five sets of experimentswere carried out on five construction workers to verify the impact of noise on the hearing and the hearing recovery.The differences of hearing loss and hearing recovery were analyzed under different types of work and noise level.This study mainly completed the research on the harmfulness of construction noise through the logic of noise monitoring,spectrum analysis,questionnaire investigation and listening experiment.This study avoids the influence of construction noise on the crowd around the field,mainly focuses on the occupational workers at the construction site,and produces noise files according to the noise exposure level of the construction site.An innovative audiometric test combining audiometric frequency domain audiometry to identify the risk of exposure to different types of work and designing temporary threshold shifts is used to determine the degree of hearing loss and hearing recovery time under different types of work and noise levels.
