ASTM WK59631

    New Classification for Determination of High-Frequency Impact Noise Ratings

    (What is a Work Item?)

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



    WK59631

    1. Scope

    Provides methods for calculating single-number ratings of high-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, E1007, and E2179.


    Keywords

    floors; IIC; high frequency impact noise; impact noise; high frequency impact rating; high-frequency impact insulation class; normalized high-frequency impact rating; HIIC; HIR; AHIR; NHIR; delta HIIC; tapping machine

    Rationale

    This standard offers a method for describing impact isolation properties of flooring and underlayment materials, focusing on the mid-high frequency range. It will be used by product manufacturers, governmental bodies, architects, and engineers.
