Increasing demands for community noise abatement, most specifically for architectural spaces such as night clubs and performance venue, have resulted in a variety of interesting design solutions to insure high performance sound attenuation, with FSTC results in excess of 80dB. This has often been accomplished with a combination of architectural construction design as well as electro-acoustic systems design such as directional subs, low frequency harmonic processing, and other systems integration devices. This paper will explore these designs and recent field results.
