| Abstract | The ASTM Standard E336-05 provides methods to assess the airborne sound isolation between a source and receiving room. In certain field situations, the determination of what constitutes the source or receiving room and its volume may not be obvious. An example is a living room (principal volume) connected to a kitchen (ancillary volume) through an opening in the wall separating the two, and the party wall under test is a surface of the living room (principal volume). Some judgment may be required to define the volume and where the sound field of the "room" should be measured. The Standard requires that the ancillary volume be disregarded if the average sound pressure level in the ancillary volume is 6 or more decibels below the average level in the principal portion of the source or receiving room to which it is coupled at all measurement frequencies. Otherwise, the ancillary volume shall be included as part of the measurement space. This paper investigates the suitability of this criterion. |
