Sažetak
The capacity of human hearing to clearly differentiate the position and/or informational contents of a referent sound source is limited when other, masking sound sources are simultaneously active. It is important to understand these limitations since nowadays novel technologies of virtual acoustics can simulate an almost unlimited number of sound sources in the created sound field, for example in the gaming industry. In this paper, a variation of the cocktail party effect was researched by performing speech intelligibility tests of a referent male speaking voice, but with the addition of up to six simultaneous, masking speaking voices from different direction around the listeners. The tests were repeated with the same setup in two rooms with different acoustic characteristics, thus having different speech transmission index values. The test results are compared and the decrease in speech intelligibility is shown in relation to the number of masking sources and their position.
