| Title of the article | A simplified method for determining the location of a local source of structural noise in a building under operating conditions |
| Abstract. | According to Federal Law No. 384 “Technical Regulations on the Safety of Buildings and Structures,” buildings are subject to noise protection requirements, which are implemented by meeting the requirements of SP 51.13330 “Noise Protection.” In this case, noise sources are traditionally transport noise, equipment noise and other sources, which position in space is known at the calculation stage. Characteristics of noise arising in structures as a result of deformation, vibration, friction, etc. are often not defined. The problem of localizing structural noise in architectural and construction practice is not sufficiently covered. There are known methods for localizing a point source of noise based on measuring the signal delay between microphones (triangulation, trilateration, etc.), however, the practical implementation of such systems can be very labor-intensive and expensive. At the same time, the use of these methods can be complicated by the fact that structural noise can differ from point noise since it can spread along extended structural elements. In view of the above problems, the purpose of the study is to develop and test a method for localizing the source of structural noise under operating conditions. The main objectives of the study are formulated in the following way. Research objectives: 1. Development of a prototype of the system for monitoring, recording and localizing the source of structural noise; 2. Development of a noise localization method based on digitization and analysis of audio signal recordings; 3. Testing of the developed method in natural operating conditions of buildings. Results. The results of a study of noise monitoring under natural operating conditions of a building are presented based on the developed prototype of the system for recording and localizing the source of structural noise. A noise localization method has been developed based on digitization and analysis of the sound signal recording by volume. The advantages and disadvantages of using the method of localizing a noise source by volume level are formulated. Conclusions. An alternative method for localizing a noise source in architectural and construction practice is proposed, the main difference of which is the principle of determining the position of a noise source by volume level. The significance of the results obtained for the construction industry lies in the significant reduction in cost and ease of implementation of the noise source localization system. |
