Abstract
Recent research at NRC's Institute for Research in Construction has demonstrated the importance of proper placement of electrical outlet boxes when the reduction of sound travelling between dwelling units in multi-family buildings is an important consideration. The research showed that poorly placed outlet boxes can significantly decrease the sound isolation of gypsum board walls - a decrease of up to six sound transmission class (STC) points, when compared to walls with no boxes, was observed. It also showed how this degradation of performance can be minimized.
