34A-2-507. Measuring hearing loss.
(1) The degree of hearing loss shall be established, no sooner than six weeks aftertermination of exposure to the harmful industrial noise, by audiometric determination of hearingthreshold level performed by medical or paramedical professionals recognized by thecommission, as measured from 0 decibels on an audiometer calibrated to ANSI-S3.6-1969,American National Standard "Specifications for Audiometers" (1969).
(2) (a) In any evaluation of occupational hearing loss, only hearing levels at frequenciesof 500, 1,000, 2,000, and 3,000 cycles per second (Hertz) shall be considered. The individualmeasurements for each ear shall be added together and then shall be divided by four to determinethe average decibel loss in each ear.
(b) To determine the percentage of hearing loss in each ear, the average decibel loss foreach decibel of loss exceeding 25 decibels shall be multiplied by 1.5% up to the maximum of100% which is reached at 91.7 decibels.
(3) Binaural hearing loss or the percentage of binaural hearing loss is determined by:
(a) multiplying the percentage of hearing loss in the better ear by five;
(b) adding the amount under Subsection (3)(a) with the percentage of hearing loss in thepoorer ear; and
