Walter Baumann

Dipl Phys Walter Baumann completed his studies in experimental physics at Heidelberg University in September 1990 with a diploma thesis about detectors at the local Max-Plank-Institute. In March 1991 he started working at G+H for research and development in acoustics and EMC. In 2020 his focus was on technical sales support and especially measuring chambers. In 2021, he assumed the position of project manager for internal and external measurement tasks at Acoustic Competence Center.

The G+H Acoustic Competence Center: a unique acoustic testing facility

Close to Mannheim, Germany, G+H’s Acoustic Competence Center (ACC) provides multiple acoustic laboratories to serve internal R&D and validate customers’ materials. Two absorbing rooms, one with wedge absorbers, one with flat absorbers, act either as full- or hemi-anechoic spaces per ISO 26101. The heavy-duty foundation in the hemi-anechoic chamber allows quantifying test objects with a load up to five tons per square meter down to a frequency limit of 30Hz. A setup of four reverberant rooms, all connected by various openings for different specimens, completes the coverage of the acoustic needs in civil engineering through the application of standards like DIN EN ISO 354, DIN EN ISO 3741 and DIN EN ISO 10140ff. Customized examinations and auxiliary investigation methods like a silencer duct per DIN EN ISO 11691, impedance tubes per DIN EN ISO 10534-2 and flow resistance measurements per DIN EN ISO 9053 are supported as well.
