Protection from temporary noise sources faces considerable difficulties (construction sites, open-air concerts, leisure and sports activities). However noisy machines in particular are constantly changing locations and run during a limited time. SATTLER CENO’s inflatable noise protection wall has especially been developed for this purpose and ensures mobile and effective noise protection wherever it is needed.
In cooperation with the Fraunhofer Institute for Building Physics (IBP) and the University of Stuttgart,
SATTLER CENO developed these especial elements for temporary noise protection. The inflatable, mobile CENO-WALL is the most effective solution for sound isolation and does not stand behind stationary noise protection walls in terms of efficiency.
Through several technical measurements and the corresponding calculation methods, the Fraunhofer Institute for Building Physics (IBP) was able to confirm the effectiveness of the CENO-WALL for noise insulation.
The results show that by using these inflatable noise protection elements alone, a sound insulation factor of more than 20 dB can be achieved. ʽInflatable noise protection elements represent a relevant novelty in the noise abatement field due to their favourable sound absorption properties and to their versatile use. In practice, their acoustic technical behaviour barely stands behind the behaviour of conventional systemsʼ. (1)
