Abstract
An acoustic isolation device includes a sleeve having a length, central axis along the length, a first end and a second end and an interior between the first end and second end, the cylindrical sleeve further comprising at least one resiliently deformable section between the first end and the second end along a least a portion of the length of the cylindrical sleeve allowing the cylindrical sleeve to be deflected, and a tab stop structure positioned along the length of the deformable section of the cylindrical sleeve and having at least one tab stop positioned in the sleeve, the cavity providing a gap around one or more sides of the at least one tab stop, wherein the at least one tab stop is movable within the cavity as the sleeve is deformed but restricts the sleeve from being deformed by more than a predetermined amount or estimated amount.
