[0025] In this embodiment, the purpose of dividing the building construction area and the area of key concern is as follows: Since the building construction area is the main source of noise, dividing the building construction area can accurately monitor the noise generated by construction activities. At the same time, the area of key concern is a sensitive area affected by noise (such as residential areas, schools, hospitals, etc.). Dividing the area of key concern can monitor the impact of noise on the surrounding environment to achieve more accurate and comprehensive noise monitoring and management.

[0026] S2. When construction is carried out in the building construction area, collect the noise data of the building construction area and the area of key concern respectively and perform normalization processing, and calculate the first comprehensive noise impact index under the construction environment based on the normalized noise data of the building construction area and the area of key concern.

[0027] Specifically, step S2 specifically includes S21 - S25:

[0028] S21. Uniformly divide the building construction area and the area of key concern respectively to generate a building construction area grid and an area of key concern grid.

That is, when the comprehensive noise impact index (the first comprehensive noise impact index) of the construction area and the key - concern area is large, it can be judged that the noise pollution is serious. In addition, according to the calculated first comprehensive noise impact index, the noise contribution degrees of the construction area and the key - concern area can be calculated respectively to evaluate the noise impact. The noise contribution degrees of the construction area and the key - concern area are respectively: , represents the noise contribution degree of the construction area, represents the noise contribution degree of the key - concern area; so when is relatively high and is relatively low, it can be shown that the construction area is the main noise source, indicating that the noise in the construction area will affect the construction workers. Therefore, the noise impact can be reduced by adjusting the construction machinery or equipment; when is relatively high and is relatively low, it indicates that the surrounding area of the construction is greatly affected by the noise and the noise does not come from the construction environment.

[0042] S3. When construction is carried out in the construction area, investigate and statistically analyze the psychological states of the construction workers and the users in the key - concern area, and establish an experience - scoring model for the construction workers and users on the construction environment, and calculate the comprehensive experience - scoring index under the construction environment.

[0091] If , then the noise impact of building construction is relatively large and noise management is required;

[0092] If , the impact of construction noise is serious, and noise management shall be carried out immediately.

[0093] As Figure 2 shown, a noise evaluation system for construction applying a noise evaluation method for construction includes:

[0094] A multi-source data acquisition module, configured to acquire noise data of a construction area and a key concern area, psychological state data of construction workers and users in the key concern area, and construction stage information data of the construction area.

[0095] In this embodiment, by integrating multiple data sources, comprehensive acquisition of noise data, psychological state data, and construction stage information data of the construction area and the key concern area is realized, so as to perform data preprocessing in subsequent steps and provide high-quality input data for the noise evaluation model. Among them, the key concern area is the area around the construction area including residents, schools, and hospitals; secondly, when collecting psychological state data, it is necessary to collect not only the psychological state data of users in the key concern area, but also the psychological state data of construction workers, because excessive noise will not only affect the life and psychological conditions of surrounding users, but also the physical and psychological conditions of the on-site construction staff.

[0096] A data analysis and processing module, configured to perform data analysis and processing on the noise data of the construction area and the key concern area, the psychological state data of construction workers and users in the key concern area, and the construction stage information data of the construction area respectively, and establish a noise evaluation model under the construction environment.

[0097] In this embodiment, the collected multi-source data is respectively preprocessed and analyzed, and a noise evaluation model based on multi-source data is established through comprehensive index calculation, so as to evaluate the impact of noise under the construction environment.

[0098] An early warning module, configured to obtain a noise score under the construction environment according to the noise evaluation model under the construction environment, so as to evaluate the noise impact of the construction environment, and at the same time determine whether to take noise reduction measures for noise management.

[0099] Specifically, the specific process of determining whether to take noise reduction measures for noise management is as follows: If the impact of construction noise is large, the construction time and construction machinery are adjusted, that is, the construction time is adjusted to the time of non-sensitive periods, low-noise equipment is selected or the construction machinery is regularly maintained; if the impact of construction noise is serious, the construction time and construction machinery are adjusted, and a sound insulation shielding device is set in the construction area.

[0100] In this embodiment, when the noise score in the construction environment is obtained, the noise impact level in the construction environment can be divided, and then it can be determined whether to conduct noise management on the construction environment according to this impact level. Among them, the means of noise management include adjusting the construction time and construction machinery, and at the same time setting sound insulation shielding devices in the construction area. Adjusting the construction time can be to avoid high-noise operations during sensitive periods (such as at night and on holidays), or arranging high-noise operations during the day or non-sensitive periods. Adjusting the construction machinery can be to select low-noise equipment (such as low-noise excavators, low-noise concrete mixers, etc.), or regularly maintain the construction machinery to ensure its good operating condition and reduce noise generation. Setting sound insulation shielding devices in the construction area means setting sound insulation barriers at the construction site to reduce noise transmission, or setting sound insulation walls or sound insulation boards around the construction area.

[0101] In summary, for a noise evaluation method and system for building construction proposed by the present invention, first, by collecting multi-source data such as noise data, psychological state data, and construction stage information data, and performing data analysis and processing, noise impact indicators for the construction area and around the construction area, experience score indicators for users and construction workers in the construction environment, and noise impact indicators of the construction stage on the construction environment are generated. These indicators accurately reflect the noise impact degree of different areas in the construction environment, and at the same time supplement the noise evaluation dimension from the perspectives of construction and users, and reveal the relationship between different construction stages and noise impact. Secondly, the comprehensive weighting method of game theory is used for weight distribution, a noise evaluation model in the construction environment is established, and the noise score in the construction environment is obtained to evaluate the noise impact of the building construction environment and conduct noise management, greatly improving the scientific nature of the evaluation model. And compared with the traditional method, the present invention significantly improves the comprehensiveness of noise evaluation data, ensuring that the noise problem is considered from multiple key levels; greatly improves the accuracy of noise evaluation, avoiding evaluation deviations caused by one-sided data or unreasonable weights; at the same time, relying on a perfect data collection and analysis system, it can manage the noise data generated by building construction more properly, providing a strong guarantee for optimizing the construction environment and reducing noise interference, and effectively improving the overall level of building construction noise management.
