The modeling programs provide a wide range of possibilities for simulating acoustic systems. This paper describes programs used in acoustics for various purposes, such as Sound PLAN, AFMG SoundFlow, WinFLAG, Comsolmultiphysics, ANSYS, Roomsim. For the purposes of the current research, the acoustic simulation of the room was carriedout. Physical parameters as impedance, sound hard boundary and normal velocity were considered. The sound pressurelevel in rooms was investigated. Possibilities of using Comsol Multiphysics in the research of acoustics were investigated. Results of the current research show high-frequency eigenmodes located in the corners of the room and in the centerof the room. Sound pressure level increased from low to medium frequency and then decreased with frequency drifts. Atthe frequency of 5000 Hz, minimum sound pressure is observed, which is associated with the decrease in the wavelengthco-occurring with the decrease in frequency.
