Abstract

Introduction. The acoustic quality of the premises significantly affects the comfort of living, working, training, lectures and recreation. The main characteristics of the sound field in the room include the noise level created by external and internal sources of man-made noise and the standard reverberation time of the sound process. The measurement takes a long time, during which the characteristics of external man-made noises change, which leads to false estimates. It is possible to improve the assessment of sound insulation by using an integral sound meter or a device for operational assessment of the acoustic characteristics (DOAAC) of the room proposed in the work.

Theoretical Results. The paper proposes a device for researching the acoustic characteristics of rooms, the basis of which is the method of synthesis of the controlled spatial correlation characteristic, which allows to evaluate the angular distribution of the sound level, to identify enclosing structural elements with a low level of sound insulation, to localize effective sound reflectors and to evaluate their contribution to the reverberation process.

Experiment. Approbation of the device in laboratory conditions showed the possibility of localizing individual structural elements, such as windows or doors, as sound penetration channels. The correlation in time between the reverberation process and individual reflectors is established and their angular position is determined. The conducted researches confirmed the possibility of applying DOAAC for the tasks of acoustic examination of premises and posed the question of developing a methodology for further application.
