Section 590
Section 590.90 Audiometric
Test
a) "Audiometric
test" means any test, using calibrated audiometric equipment, to determine
the status of the hearing system (77 Ill. Adm. Code 682.100).
b) An
audiometric test will be purchased when:
1) the
customer does not have documentation of the level of hearing loss to determine
eligibility for Vocational Rehabilitation Services; and
2) the
customer wants or will benefit from hearing aids.
c) An audiometric test must be performed prior to the hearing evaluation.
d) An audiometric test shall align with 77 Ill. Adm. Code 682.300
Established Test Procedures and consist of:
1) an air and bone conduction test. Air and bone conduction test
results shall be obtained for each client in the manner specified in the ANSI
Methods for Pure Tone Threshold Audiometry (see 77 Ill. Adm. Code
682.105(a)(2));
2) masking. Masking shall be applied to the non-test ear whenever
the test stimulus, which is delivered to the test ear, arrives at and/or is
likely to be perceived in the non-test ear;
3) speech reception threshold. Speech reception threshold shall
be accomplished with a speech audiometer as defined in and calibrated to the
ANSI Specifications for Audiometers (77 Ill. Adm. Code 682.105(a)(1)). The
spondaic words shall be presented by recording or live voice. The results from
either recorded or live voice testing shall be in decibels hearing level (dBHL);
4) speech discrimination/identification tests. Speech
discrimination/identification tests shall be administered using a speech
audiometer as defined in and calibrated to the ANSI Specifications for
Audiometers (77 Ill. Adm. Code 682.105(a)(1)). The results shall be recorded
as the percentage of the total number of words correctly identified at a
specified presentation level;
5) most comfortable loudness level. "Most Comfortable
Loudness" shall be obtained using sound or speech via recorded or live
voice presentation and shall be measured and recorded in dBHL; and
6) uncomfortable loudness level. "Uncomfortable loudness
level" shall be obtained using sound or speech via recorded or live voice
presentation and shall be measured and recorded in dBHL.
