Vibratec has supplied specially designed steel beams with integrated springs and cushions, to carry a roof-top basketball court in Odense, Denmark.
This intervention was done to prevent the noise of bouncing balls and running players disturbing people living in apartments directly below. The result went beyond expectations and measurements showed Lp, max values lower than 15dB(A). This is more than 20 dB lower impact noise compared to a solution with concrete slab on a mineral wool mat.
