During each operation of the ventilation system, noise is generated, which related to fan during transport air. Attention must be paid this noise, as and depressions caused by are transmitted through pipes air distribution elements thus disturb indoor environment buildings. Each part system either absorbs or generates noise. Noise propagating generated in fittings can reduced several ways, for example dimensioning pipes. However, vibration that occur directly handling unit eliminated another way. Therefore, a component called silencer installed behind unit. For correct dampers, it necessary monitor not only their acoustic attenuation, but also its pressure loss. The aim work verify authenticity values given calculation program from company Technov. To achieve goal, was build measurement-verified CFD model, would allow silencers with other dimensions.
