Abstract: An acoustic configuration (1) for acoustic insulation, with the configuration includes a floor covering (5) attached to a floating floor with elastic skates (4) resting on a substrate (3) (10), the floating floor including skates (4) that are substantially elastic. The floating floor consists of a modular assembly of prefabricated rigid panels (2) with a density of 0.5 to 6, positioned edge to edge with an element of position adjustment that is either male or female, with the skates being homogeneous one-piece elements attached inside the panel, and with the total seat surface ratio Sta of the skates on the substrate on the total surface area Stp of the panel, Sta/Stp being 0.03 to 0.08. In one variant, shims are interposed between the skates and the panel. In the implementation method, a layer of fibrous insulation can be interposed between the substrate and the floating floor.

Abstract: An incubator including a substantially airtight heated chamber equipped with a door to access the heated chamber; a culture plate with multiple wells placed in the heated chamber, the culture plate being adapted to contain an organism in at least one of the wells; and means associated with the heated chamber and controlled from the exterior to remove the organism from a well in which it is contained to put it in another well filled with new culture medium.
