Low-reflection half-room
An automotive supplier commissioned G+H Noise Control with the delivery and installation of a noise control measurement room in room-in-room construction for acoustic measurements for its plant in Lower Saxony.
The order included the following services:
- Design of a foundation plate with calculation of the required MAFUND bearings for decoupling.
- Coating of the base plate
- Static calculation of the base plate
- Creation of the lost formwork for the base plate
- Sound measurement room with SONEX® K
- Inner lining with ASONAD-MF wedges, designed for a cut-off frequency of 100 Hz
- Lighting by means of dimmable LED lights
- Ventilation of the room by means of 2 nozzle ducts and supply and exhaust air silencers designed according to the ambient conditions.
- Final measurement to determine the lower cut-off frequency of the absorbers and the decoupling frequency of the MAFUND isolators.
The sound enclosures were handed over to the customer on schedule.
