ASTM WK63897

    New Classification for Determination of Low-frequency Impact Noise Ratings

    (What is a Work Item?)

    Developed by Subcommittee: E33.10 | Committee E33 | Contact Staff Manager



    WK63897

    1. Scope

    This classication provides methods for calculating single-number ratings of low-frequency impact noise transmission, based on one-third octave band impact noise levels generated by the standard tapping machine as described in Test Methods E492 and E1007.

    The proposed standard addresses impact noise in a frequency range not addressed by other ASTM standards. It will be used by designers and testing agencies.


    Keywords

    oors; low-frequency impact rating; LIR; low-frequency impact insulation class; LIIC; tapping machine

    The title and scope are in draft form and are under development within this ASTM Committee.
