    (What is a Work Item?)

    Active Standard: E336 - 19

    Developed by Subcommittee: E33.03 | Committee E33 | Contact Staff Manager



    WK63236


    Keywords

    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. Background adjustment method needs updating. 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 issue originally part of this work item has been resolved by an approved ballot.
