Abstract
In an acoustic building structure corresponding to the mass-spring-mass insulation principle, the two masses of the mass-spring-mass system are each formed of at least one rigid element (1,2) and are separated by at least one panel (4) of mineral wool combined with at least one air gap (5). The acoustic structure is such that the rigid elements (1,2) are trays with a U-shaped cross section and are lined on the inside of the U with at least one mineral wool (3).
