CALCULATION OF ADDITIONAL FUND OF SOUND ABSORPTION IN NOISY PLACES
Abstract
The document SP 51.13330.2011 "Noise protection" establishes standards for noise levels in various premises. Such compliance requires the compliance of premises to certain acoustic conditions, including a time-standard reverberation RT60. However, the document imposes no requirements on RT60 in the halls of cafes, restaurants, production areas and in areas with less than 500 m 3 in principle. In order to reduce the noise to the specified level can be calculated by identifying the supplementary Fund absorption, which is required in the room. In this article the method of calculation of additional fund absorption, which is required in the place to reduce noise levels to standard values.
