Advantages
Acoustic insulation achieved DnTA > 75 dBA.Plastering ensures the tightness of the floor.Mass-spring-mass system with absorption at low, medium and high frequencies.The direct placement of plasterboard of 15 and SONODAN® PLUS increases the pre-slab insulation at low, medium and high frequencies.The material in the first cavity dampens impulsive noises of low frequencies.The membrane between boards displaces the resonance of the system towards less audible frequencies and improves isolation at low frequencies.Mineral wool avoids the “drum” effect between boards.The waterproof chamber may be the minimum allowed by the premises.The spring acoustic hanger prevents excitations at low, medium and high frequencies.Light system providing good results and speed of execution
Application
Musical premises with emission 100-105 dBA and night time: live music, discos, wedding halls, etc.Music recording studios.
