摘要:
A glazing unit with an improved vibroacoustic damping property including at least one sheet of glass and at least one vibroacoustic damping strip that is attached to at least one of the faces of the glass sheet and that includes at least one component made of damping material having a loss factor greater than 0.2. The strip is not joined to any other device on the opposite side from the glass sheet and the component made of damping material has a Young's modulus greater than 800 MPa, at 20° C., for a particular frequency corresponding to the critical frequency of the glazing unit to within plus or minus 30%.
摘要:
A glazing unit having improved vibroacoustic damping properties, including: at least one glass sheet; at least one vibroacoustic damping strip, the strip including at least one element made of damping material and the strip being fastened to one of the faces of the glass sheet. The face of the strip facing the glass sheet has a surface area in contact with the glass sheet which is strictly inferior to the surface area of the face of the strip facing the glass sheet. The glazing unit makes it possible to damp noise and vibrations while taking up little space.

摘要:
An acoustic damping article includes a substrate, wherein the substrate has a surface area S. The acoustic composition further includes a polymer resin. The polymer resin coats partially the surface area with a set of areas. The ratio of the coated areas over the surface area S is less than 1 and the polymer resin coverage is not greater than about 500 g/m2.

摘要:
A stud for a partition or wall has at least two frame members coupled together by a compliant member formed from a material that increases resilience between the frame members. The coupled frame members form a stud for the partition. The partition has a first stud with rigid first frame members coupled together by the compliant material. A second stud is joined to the first stud to form a frame. The second stud rigid second frame members are coupled together by the compliant material. Boards are joined to the frame on opposite sides thereof to form the partition.
