    airborne sound transmission loss; apparent sound transmission class; apparent transmission loss; flanking transmission; noise isolation class; noise reduction; normalized noise isolation class; sound transmission coefficient; sound transmission loss; transmission loss;;

    Rationale

    Clarification is needed that cabinets refers to built in cabinets. Guidance is needed on minimum microphone positions and measurement times for direct measurement of coupled spaces. Guidance is needed on minimum precision for recording of data and rounding during calculations. A flow chart to clarify implementation of the standard is being considered. The curing time and background adjustment issues originally part of this work item have been resolved by a approved ballots. A new issue raised is a need to clarify language on various types of spaces and rooms.
