摘要：

A comparison of calculations of a check valve operating on a gaseous medium by numerical and numerical-analytical methods is given, the influence of the sound pressure level in the valve on the flow velocity is considered, and the influence of the valve walls on propagation of noise in a room is considered using numerical and analytical methods.
