An attenuation device 10 for reducing the acoustic coupling between two surfaces, the device 10 comprises: a housing 20; a foam attenuator 30 and an engagement member 40. Housing 20 comprises sides 22, two upper surfaces 24, 24', and a base 26, and defines a channel 27 dimensioned to receive foam attenuator 30 therein in a close fit. The base 26 of housing 20 is adapted for engagement with a first surface. Foam attenuator 30 comprises a foam body defining a T-shaped slot 32 therein which is dimensioned so as to receive engagement member 40 therein in a close fit. The entrance to slot 32 is define by abutments 34, 34' which project above the planar upper surface of 36 of foam attenuator 30. Engagement member 40 comprises a planar member 42, the upper surface of which is adapted for engagement with a second surface. Engagement member 40 further comprises lower portion 43 for engagement within slot 32 in the foam attenuator 30. Also provided is a method of acoustic coupling between two surfaces. |
