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.


    Keywords

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

    Rationale

    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.

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