Abstract: An acoustic mount is described for damping vibrations between a primary structure of a building and a secondary structure of a building and which has a vibration damper interposed in use between the primary and secondary structures. The vibration damper is resiliently compressible in the axial direction and has at least one resiliently compressible damper element which is elongated in the axial direction so that the axial length of the damper element is greater than half of a transverse width thereof. The damper element reduces in cross sectional area in the axial direction; has a convex outer surface in planes containing the axial direction; and possesses non-linear axial deflection or compression characteristics under a range of static loading conditions enabling effective vibration damping or vibration isolation for a substantial range of loadings of the acoustic mount in use.
