G+H Industrieschallschutz GmbH was commissioned to optimise and expand the noise protection hall at an airport in the form of a retrofit. During previous investigations, it was determined that the engines, which are too close to the fuselage, receive too little airflow and that the ground emissions for the neighbouring residential area must be reduced. The airflow conditions in the hangar were improved to ensure a trouble-free test run of the engines.

The construction project was completed on time within eight months.
