Effect of incomplete height of partitions on acoustical parameters of operating areas

Operating areas are currently widely used in public service. They refer to rooms with a mass presence of people. The quality of customer service is influenced by a large number of people talking to each other at the same time. As a result, the audibility and intelligibility of speech in the operator-client pair decreases. Partitions of an incomplete height are arranged to improve the quality of customer service in operating areas.

Purpose: Methodology is proposed to evaluate acoustic changes in rooms with a mass presence of people from the standpoint of ensuring speech intelligibility.

Methodology: The method for assessing the speech intelligibility between the operator and client in space with partitions of incomplete height.

Research findings: The proposed method can be used to evaluate acoustic changes rooms from the standpoint of the speech intelligibility. The example is given to the technique used to solve this problem.

Practical implications: The proposed method and developed computer program for its implementation will provide a necessary acoustic mode through a purposeful design of space-planning solutions for partitions and determine their sound-absorbing and sound-insulating characteristics.
