Numerical Method for Calculating Noise in Flat Rooms with Partitions of Incomplete Height

In office premises, it is customary to place operators’ seats in cabins made of partitions of incomplete height. The device of the cabins ensures the confidentiality of communication between the client and the operator and improves speech intelligibility. At the same time, the presence of partitions of this type significantly affects the distribution of sound energy compared to its distribution in a room without partitions. In addition to the fact that partitions shield direct sound coming from neighboring workplaces, they also significantly affect the formation and distribution of reflected sound energy in the general space of the office space. For this reason, at the design stage of office premises with workplaces separated by partitions of incomplete height, it is necessary to make noise calculations taking into account the presence of partitions in them. For this purpose, the article proposes a calculation method that makes it possible to take into account the redistribution of reflected sound energy that occurs during the installation of partitions. The method has been tested experimentally and can be used in office premises belonging to flat-proportioned rooms.
