Advantages
Acoustic insulation achieved DnTA > 65 dB.Plastering ensures the tightness of the floor.Mass-spring-mass system with membrane resonator (absorption at low frequencies) and absorbent at medium and high frequencies.The membrane between boards displaces the resonance of the system towards less audible frequencies and improves the low frequency.Its thermal insulation capacity can be improving by increased the thickness of the mineral wool.The cavity may be the minimum allowed by the premises.The rubber acoustic hanger prevents mid-low, medium and high frequency excitations.Light system better for structural strength and speed of execution.
Application
Premises with sound emission between 85-90 dBA and night time: breweries, restaurants, cocktail bars.Music classrooms in schools.Music schools: individual instrument booths.Clubs in shopping centers.
