Semi-anechoic chambers

Design, supply and installation of acoustical coating for a cell for noise measuring of powertrain whose services provide an UN index of reactivity, LK less than 1.3 dB (A) in the two running conditions: a) 2500 rpm 1 'b) 4000 rpm 1 '. The hall has been ''undressed'' of all systems (electrical, fire, fuel distribution line, lighting, etc) and completely coated with UN treatment and high sound absorption extended to all outer surfaces of the room (except the floor) implemented with wedges and paneling, specially designed and sized. Particular care has been taken to extend treatment to all moving parts for the necessary maintenance on the technologic plants in the room (access, air pipes, visual room console, etc)
