Rooms constructed with hard flat surfaces are prone to encounter problematic noise. Even at low levels, noise annoyances will affect the acuity of wanted sound such as music or speech and cause confusion and anxiety. Environments maintaining prolonged mid-power or even brief durations of high-power noise levels may lead to human health and well being issues. This presentation will explore the historic development and use of cavity resonators as an acoustically-responsive design solution to control adverse noise propagated within hard surfaced enclosures. It will examine acoustical masonry as a structural wall system that can be utilized to effectively suppress problem noises and improve the acoustical atmosphere for safe, affable, human occupation.
