Ill. Admin. Code tit. 89, § 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.
Notes
State regulations are updated quarterly; we currently have two versions available. Below is a comparison between our most recent version and the prior quarterly release. More comparison features will be added as we have more versions to compare.
Any customer determined to have a hearing disability as documented in the case record and for whom a hearing aid is expected to be a necessary service must undergo a hearing evaluation and a hearing aid evaluation.
a) A hearing evaluation shall consist of:
1) air and bone conduction testing;
2) speech reception threshold;
3) speech discrimination ;
4) most comfortable loudness level; and
5) uncomfortable loudness level.
b) A hearing aid evaluation shall consist of:
1) selection of an appropriate hearing aid, based upon the outcome of the hearing evaluation (89 Ill. Adm. Code 590.90(a));
2) fitting of the hearing aid;
3) adaptation and services of the hearing aid;
4) testing of the hearing aid by means of an audiometer calibrated to American National Standards Institute standards (ANSI/ASA S3.6 -2010, with no later amendments, available from ANSI, 1899 L Street, NW, 11th Floor, Washington DC 20036); and
5) other testing allowed pursuant to 77 Ill. Adm. Code 682.300, the Hearing Instrument Consumer Protection Code.
