Ariz. Admin. Code § tit. 9, ch. 13, art. 1, tbl. 13.3
Screening Type | Pure Tone Audiometry | Pure Tone Audiometry/Tympanoetry | Otoacoustic Emissions |
Grade Level | All students who are cognitively and behaviorally able to participate. | Tympanometry may be added to pure tone screenings at the discretion of the screening program. | Initial Entry to preschool or kindergarten |
Students who are cognitively or behaviorally limited in their ability to participate in pure tone screenings | |||
Passing Criteria | Screen each student's ears, with the response recorded at the following criteria: | ||
1000 Hz at 20 dB HL, 2000 Hz at 20 dB HL, and 4000 Hz at 20 dB HL; | The height of the peak acous tic immittance is > 0.3 mmho, mL, or compliance; or The tympanometric width or gradient is < 250 daPa; and 1000 Hz at 20 dB HL, 2000 Hz at 20 dB HL, and 4000 Hz at 20 dB HL; | The display screen of the otoacoustic emissions device indicates results that the student has passed | |
Otoacoustic Emissions Screening | |||
A. Otoacoustic Emissions devices may be used to screen the following populations: 1. Students who are between the ages of one year but less than six years of age who cannot participate in pure tone hearing screening. 2. Students who are six years of age and older who cannot participate in pure tone hearing screenings, for example children with special healthcare needs and children with developmental delays or disabilities. B. Otoacoustic emissions screenings do not measure the child's ability to detect or respond to sound but measure the response of inner ear structures to auditory stimulation. Therefore, otoacoustic emissions screening should not be used in lieu of pure tone audiometry screening for those students that are able to participate. | |||
