(a) The Wyoming Newborn Hearing Screening includes: (i) An initial hearing screening according to Section 5 of this Chapter; and (ii) A rescreening, as necessary, according to Section 6 of this Chapter. (b) The Wyoming Newborn Hearing Screening must be performed according to one of the following methods: (i) Auditory Brainstem Response (ABR); (ii) Automated Auditory Brainstem Response (AABR); or (iii) Otoacoustic Emissions (OAE), either Transient Evoked OAE (TEOAE) or Distortion Product OAE (DPOAE). (c) The criteria to pass the Wyoming Newborn Hearing Screening is established as follows: (i) If ABR is performed, the normal ABR must be to click stimulus at 35 dBnHL (decibels above normal hearing levels) or less in each ear; (ii) If AABR is performed, the normal AABR must be to click stimulus at 35 dBnHL or less in each ear; (iii) If TEOAE is performed, the normal TEOAE response must be for click stimulus at 84 dBSPL (decibels of sound pressure levels) presentation level or less in each ear; or (iv) If DPOAE is performed, the normal DPOAE response must be 1500-6000 Hz (Hertz) stimuli at 65-55 dBSPL or less in each ear. (d) The Wyoming Newborn Hearing Screening must be completed in each ear. (e) Stimulus presentation level and the arrangement of electrodes and transducers of the hearing screening equipment must be in accordance with manufacturer specifications. (f) Regardless of the timing requirements under Sections 5 and 6 of this Chapter, the Wyoming Newborn Hearing Screening and rescreening may be delayed due to transfers and medical contraindications. The birthing hospital, trained midwives, and attending physicians outside of hospitals shall document the delays, and ensure hearing screening has taken place prior to ultimate discharge.
