    (What is a Work Item?)

    Active Standard: E413 - 16

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



    WK72581


    Keywords

    architectural acoustics; building design; ceiling attenuation class (CAC); field sound transmission class (FSTC); noise isolation class (NIC); normalized noise isolation class (NNIC); partitions (buildings); sound insulation rating; sound transmission class (STC);;

    Rationale

    The existing process for determining the classification involves rounding transmission loss values and then manipulating the rounded values. It is not in general good practice to round before final calculations are performed. This ballot is will address the rounding associated with the calculation of the Sound Insulation Classification
