Delivery and assembly of sound measuring room

+H Noise Control received an order for the manufacture, supply and installation of a sound measurement room. The original order comprised the manufacture, delivery and installation of a soundproofed room in the SONEX® K system with a sound-absorbing lining in the SONEX® W system and a vibration-insulated floor structure made of wood fibre boards using MAFUND. The aim was to reduce the external sound level from 75 dB(A) to 35 db(A) on the inside of the room.

During the detailed technical clarification in the course of the execution, the wish was expressed to use the room additionally as a measuring room with a lower limit frequency of 200 Hz, so that during the production phase a replanning and redesign of the room as well as the vibration isolation became necessary.

At the end of the project, the soundproofing properties were verified by measurements at the customer's site, and the selected design was able to meet or exceed the requirements.
