Table1: Worker's compensation hearing loss statutes by state. Low fence refers to the average threshold below which 0% impairment is assigned. High fence refers to the average threshold above which 100% impairment is assigned. Weighting refers to relative contributions of better ear impairment and worse ear impairment to binaural impairment (i.e., 5:1 indicates that the better ear is weighted five times as much as the worse ear). This weighting is applied after calculation of the monaural impairment, for each ear. Source: Department of Labor (2006)
