Ohio Administrative Code › Title 4747 - Ohio Speech and Hearing Professionals Board › Chapter 4747-1 - General Provisions › Section 4747-1-19 - Rules on appropriate test procedures

Current through all regulations passed and filed through July 1, 2024
For the purpose of dealing in or fitting of hearing aids the
				following test procedures performed bilaterally are considered to be
				appropriate, and as prescribed by division (J) of section
				4747.12 of the Revised
				Code.
(A) Tests of threshold.
Puretone air threshold tests must be performed at least at two
				hundred fifty, five hundred, one thousand, two thousand, three thousand, four
				thousand, and six thousand Hertz. Bone-conduction threshold tests must be
				performed at least at five hundred, one thousand, two thousand, and four
				thousand. On clients whose bone-conduction thresholds have been previously
				measured, and those measures are part of the client's permanent record, new
				bone-conduction testing may be omitted if there has been no change in the air
				conduction thresholds greater than 5dB. Appropriate masking shall be used, with
				levels indicated on the test record, whenever necessary to obtain valid
				results.
(B) Test of
			 tolerance includes most comfortable listening level (MCL) and uncomfortable
			 listening level (UCL).
(C) Test of
			 speech awareness or speech reception threshold, and speech understanding or
			 speech discrimination. All such tests are to be recorded in writing, and if the
			 examiner was unable to complete any tests because of the client's inability to
			 perform for any reason, that inability should be clearly stated and the reasons
			 fully noted on the test record. All testing should be done only for the purpose
			 of dealing in or fitting of hearing aids utilizing traditional state-of-the-art
			 procedures. Appropriate masking must be used, with levels indicated on the test
			 record, whenever necessary to obtain valid results. Measuring instruments other
			 than audiometers may be used under division (J) of section
			 4747.12 of the Revised Code,
			 provided they are used with an audiometer either separately or
			 together.
(D) Test environment.
The test environment should meet "American national standards
				institute" (ANSI) standards (SID 1996) or latest revision as adopted;
				otherwise, the test environment must be described on the test record as quiet,
				average, or noisy.
(E)
			 Symbols.
Symbols used in recording test results must appear in a legend
				on the face of the test record.
(F) View of ear canal:
The licensee or trainee shall use an otoscope to complete an
				ear canal inspection of both ears. Any identified abnormalities shall be noted
				on the test record.
(G)
			 Calibration of equipment:
Electroacoustic analysis and calibration of testing equipment
				shall be completed annually on any test equipment, which record shall be kept
				for two years.
(H) Medical
			 referral:
A licensee should advise a prospective hearing aid user to
				consult promptly with a licensed physician (preferably an ear specialist)
				before dispensing a hearing aid to the perspective hearing aid user, and
				promptly document the fact that such a referral was made in the individual's
				case record, if it is determined through documented case history, actual
				observation, or review of any other available information concerning the
				prospective user, that any of the following conditions exist:
(1) Visible congenital or traumatic deformity
			 of the ear.
(2) Visible evidence of
			 cerumen accumulation or a foreign body in the ear canal.
(3) History of active drainage from the ear
			 within the previous ninety days.
(4) Acute or chronic dizziness.
(5) Unilateral hearing loss of sudden or
			 recent onset within the previous ninety days.
(6) History of sudden or rapidly progressive
			 hearing loss within the previous ninety days.
(7) Pain or discomfort in the ear.
(8) Audiometric air-bone gap equal to or
			 greater than fifteen decibels at five hundred, one thousand, and two thousand
			 Hertz.
