Section 10-214-3 - Audiometric screening(a)Personnel: School nurses, registered nurses, speech pathologists, audiologists, trained aides to school nurses, licensed practical nurses, and trained volunteers may perform audiometric screening. All persons who conduct audiometric screening shall have completed six (6) hours of training in this area including practice supervised by a properly trained school nurse, speech pathologist or audiologist. Children under age six (6) or handicapped students shall be screened by persons with specific training and experience in screening children in these categories.(b)Environment: Screening shall be performed in an acoustic environment sufficiently quiet for a subject with normal hearing sensitivity to hear the test stimuli at the screening levels.(c)Equipment:(1) Audiometers used shall provide calibrated puretone stimuli at each of the following frequencies for each ear: 1,000, 2,000, 4,000 Hz, at a hearing level of 20 dB for 1,000 and 2,000 Hz and 25 dB at 4,000 Hz.(2) Audiometers used shall meet the current American National Standards Institute specifications for audiometers and shall be assessed at least annually for adequate calibration. A statement showing the date and results of last calibration shall be kept with each audiometer.(d)Screening: Each pupil examined shall receive calibrated puretone, air-conducted stimuli for each ear at the following frequencies and levels: 1,000 Hz, (20dB), 2,000 Hz, (20dB) and 4,000 Hz (25dB). In lieu of puretone audiometric screening, tympanometric procedures may be substituted where it can be shown that identification of conductive and sensori-neural impairments is not significantly affected.(e)Standard: A pupil who fails to respond to one or more of the three required screening frequencies in either ear shall be suspected of having an impairment or defect of hearing pursuant to Section 10-214 of the Connecticut General Statutes and defined by Section 10-214-1(d) of these regulations.Conn.
