audiometric instruments approved by nationally recognized authorities in the field of
hearing loss.] AN AUDIOLOGIST UTILIZING AUDIOMETRIC INSTRUMENTATION THAT
MEETS THE FOLLOWING CRITERIA:
(I) ANSI 3.6-1996;
(II) ANSI S3.43-1992; AND
(III) ANSI 3.39-1987 OR ANY ANSI STANDARD THAT SUPERSEDES THE

MEETS THE ANSI 3.1-1991 CRITERIA FOR MAXIMUM PERMISSIBLE AMBIENT NOISE
FOR AUDIOMETRIC TEST ROOMS.
(3) AN AUDIOLOGIST MAY OBTAIN!
(I) BEHAVIORAL-PSYCHOACOUSTIC-MEASUREMENTS WITH
INSTRUMENTATION THAT USES INSERT EARPHONES, REFERENCED IN ANSI 3.6 1996.
(II) ELECTRODIAGNOSTIC MEASUREMENTS SUCH AS AUDITORY
EVOKED POTENTIALS OR DISTORTION PRODUCT OTOACOUSTIC EMISSIONS TO
DETERMINE THE NATURE AND EXTENT OF WORKPLACE HEARING LOSS.

COMPENSABLE HEARING LOSS.
(b) (1) The percentage of hearing loss for purposes of compensation for
occupational deafness shall be determined by calculating the average, in decibels, of
the thresholds of hearing for the frequencies of 500, 1,000, [and] 2,000, AND 3,000
HERTZ [cycles per second] in accordance with [paragraphs] PARAGRAPH (2) [and
