11. An acoustic mount for damping vibrations between a primary structure of a building and a secondary structure of a building in which the primary and secondary structures are mounted or coupled in use to each other whilst being separated from each other in an axial direction, the acoustic mount including:
a vibration damper which is interposed in use between the primary and secondary structures so as to damp vibrations and thereby limit the transmission through the vibration damper of the vibrations in one of the structures to the other of the structures, the vibration damper being resiliently compressible in the axial direction;
wherein the vibration damper 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;
wherein the or each said at least one damper element reduces in cross sectional area in the axial direction;
wherein the or each said at least one damper element has a convex outer surface in planes containing the axial direction;
wherein the or each damper element is located atop a damper column which extends in and is resiliently compressible in the axial direction;
wherein there are multiple columns connected together with a damper element atop each of the columns projecting above regions where the columns are connected together; and
whereby the vibration damper 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.
