Résumé

A new performing arts program project, established within an existing urban high school to promote continuing education for dance, music and drama, was reviewed in January 2011. A review was done of existing conditions and recommendations were revised to provide all the necessary elements and details to ensure optimum sound isolation. The corresponding level differences and lab-measured transmission loss values for a 190mm concrete block wall are compared. A primary concern was the common floor slab and its potential to flank sound underneath the new wall systems. An initial, subjective evaluation of the sound isolation improvement indicated that the construction between the Dance Studio and Music Room is now optimized. To validate the correlation of beam vibration to the receiving room sound pressure, pink noise was generated within the Drama Room at an overall, average level of 97 dBA.
