Abstract
The overwhelming majority of acoustic data that are available to most architectural design professionals is in abbreviated single-number ratings, without details or full test reports. Omitted key details can greatly affect the actual performance. Despite best intentions to satisfy codes and criteria, most of these designers do not adequately understand the acoustic fundamentals to recognize and then avoid significant problems and under-designed projects. Examples of problems with data regarding sound isolation, HVAC noise, and sound-absorption will be discussed, along with suggestions toward better understanding and more desirable/reliable end results.
