The right acoustical configuration and selection of suitable materials demands both far-reaching expertise and extensive experience in their practical application. That’s why G+H has set up a dedicated acoustics development center to test the insulation- and vibration-related properties of materials and components. We are also committed to developing new solutions for our customers in order to provide them with the most effective protection against noise and vibrations in their particular area of application. We also measure various parameters relating to acoustics and vibrations at our customers’ sites.
