16 Tex. Admin. Code § 112.97 - Sound-Level Measurements - Audiometers and Audiometric Testing
(a) Audiometers and audiometric testing
devices shall meet the current standards of the American National Standards
Institute (ANSI) or the International Electrotechnical Commission.
(b) Audiometric testing not conducted in a
stationary acoustical enclosure.
(1) A
notation shall be made on the hearing test if testing was not done in a
stationary acoustical enclosure. Sound-level measurements must be conducted at
the time of the testing to ensure that ambient noise levels meet permissible
standards for testing threshold to 20 dB based on the most current ANSI "ear
covered" octave band criteria for Permissible Ambient Noise Levels During
Audiometric Testing, or the test environment shall have a maximum allowable
ambient noise level of 42 dBA.
(2)
Ambient noise level of the location of the audiometric testing, if not done in
a stationary acoustical enclosure, shall include a notation on the hearing test
of the following items:
(A) type(s) of
equipment used to determine ambient noise level;
(B) model and serial number of equipment used
to determine ambient noise level;
(C) date of last calibration of equipment
used to determine ambient noise level; and
(D) the ambient noise level of the test
environment.
(c) Audiometric testing conducted in a
stationary acoustical enclosure.
(1) A
notation shall be made on the hearing test if testing was done in a stationary
acoustical enclosure.
(2) A
stationary acoustical enclosure includes, but is not limited to, an audiometric
test room.
(A) An audiometric test room is
any enclosed space in which a listener is located for the purpose of testing
hearing. An audiometric test room may also be known as:
(i) an audiometric test area;
(ii) a hearing test space; or
(iii) a hearing test room.
(B) An example of an audiometric
test room would be a prefabricated room known as:
(i) an audiometric test booth;
(ii) a suite; or
(iii) a sound treated room.
