AbstractAbout AuthorsReferences
The problem of determining the value of the required isolation of transport noise with translucent structures on newly constructed capital construction objects, which results in excessive requirements for the sound insulation of translucent structures at the design stage, is considered. One of the reasons for this is the lack of clear recommendations in the current regulatory documentation for determining the value of the average sound absorption coefficient required to determine the acoustic constant of the room and the coefficient that takes into account the violation of the diffusivity of the sound field. The Department of Construction Acoustics and Facade Inspection of the State Budgetary Institution “TSEIIS” has collected statistical data on measurements of transport noise isolation for 150 capital construction projects in Moscow. The accumulated measurement statistics make it possible to calculate the average values of the sound absorption coefficient and determine the degree of influence on the required insulation of transport noise, depending on the parameters of the premises (such as the presence of furniture, etc.). According to the results of calculations, it is established that the coefficient values can vary in the range from 0.03 to 0.15 and more, and the calculated value of the required sound insulation by 3–15 dB, respectively. It is necessary to consider the issue on making changes in the relevant regulatory documentation for determining the parameter of the average sound absorption coefficient and use the results of field tests when making changes to the regulatory documentation.
