Simulation of Sound Field in a Classroom
Peculiarities of sound field in a classroom simulation are considered. The simulation of reverberation time, sound pressure level as function of distance and frequency, signal to noise ratio, location, speech intelligibility and articulation loss of consonants as function of distance from sound source are given. The simulation results of one speaker and two loudspeakers systems in frequency and spatial areas are shown. Ill. 8, bibl. 10 (in English; summaries in English, Russian and Lithuanian).
