A manufacturer of components for passenger cars placed an order with G+H Noise Control to supply and install a low-reflection lining for a sound measurement room. The room is used as an acoustic test bench to evaluate individual components under acoustic free-field conditions. The order also included the assembly and delivery of a double-leaf sound-insulating door.
The ceiling and the front wall of the sound measurement room were fitted with flat absorbers type G+H SONEX WF 350. The end walls were lined with a G+H ASONAD ML 800 wedge absorber system.
