SIMA silencers are absoption silencers with 100, 150 or 200 mm baffles. They represent the best solution both for abatement ratio and costs. They are intended to reduce the noise that propagates through the ventilation ducts. Noise reduction, which passes through the distribution network, implyes the decrease of the sound pressure level that goes to the terminal units and then spread in the treated environment.
