The article deals with the importance of mathematical simulation. It explains the application of the programme CadnaA for simulating noise dispersion in closed environments. Two mathematical simulations are presented. The first simulation is a two-room apartment with the area of 44 m2 ; it has a kitchen, WC and bathroom (in one room) and a storage room. The second simulation is a hairdresser's salon of 40 m2 with three working spaces, WC, and a staff dining room. The simulations are performed with the frequencies of 63 Hz, 500 Hz, and 4000 Hz. In order to verify the correspondence of results of the simulations with natural measurements, a comparative noise measurement was taken in an apartment matching the first simulation. Measurement results were compared with the model and presented in the article.
