Heydar Aliyev Center in Azerbaijan, Baku is an architectural landmark in terms of its symbolic contribution to the city. Contemporary organic architecture of the building, having the signature of the architect Zaha Hadid, ends up with no comers or rectilinear surfaces. Acoustical excitement starts up with the challenge of solving out the acoustical defects related to those mostly curvilinear forms and highly reflective surfaces. Inner galleries having reverberationtimes up to 10 s arc aimed to be taken under within limits of 2.5 s for optimum foyer acoustical characteristics. Thechallenge starts with the architects no compromise on any architectural design visual alteration. So as to satisfy thesound absorption for desired acoustical performances with architecturally transparent materials that cause the leastvisual modification, much effort has been spent on the compromise in between materials' visual and acoustical features. Acoustically transparent materials arc studied under the consideration of architectural continuum. Acoustically transparent plasters with the least visual dissimilarities in comparison to regular paints or plasters are searched. These materials are used as a finish material over perforated backing. This paper mainly discusses about the acoustical per- formance of wall construction systems for such a challenging design for both satisfying the energy decay in terms of having the optimum sound pressure levels indicating noise levels, and satisfying sound intelligibility characteristics within given such scheme so as to provide acoustical comfort for the users.
