    This forum is mainly for Windows server 2008 Application compatibility and certification issues

    However, following formula may help you

    Db = 20 *log (K/100)

    Where k = loss in %

    Db = loss in decibels.

    So

    Db = 20 * log (40/100)

    Db = 20 * -0.3974

    Db = -7.959
