Abstract
An acoustic isolation structure providing an acoustically isolated opening nd comprising coaxial inner and outer annular structural members defining an irregular annulus between them. Acoustical isolation material is provided within this annulus to acoustically uncouple the two members. Radially overlapping structural rings extending from the members into the annulus limit lateral movement of the inner member and preserve the generally coaxial relation of the members.
