• Auditory neuropathy affects up to 15% of infants with hearing impairment.1

• Auditory neuropathy is a disorder characterized by dysfunction in the auditory pathway

beyond the outer hair cells of the cochlea.

• OAE technology does not assess the auditory pathway beyond the outer hair cells of the

cochlea and will pass infants with auditory neuropathy.

• ALGO® AABR® technology screens the auditory pathway beyond the outer hair cells of the

cochlea to the brainstem and will refer infants with auditory neuropathy.

• Two-step screening programs using OAE followed by ABR are at risk for missing infants with auditory neuropathy, since infants who pass the OAE screen do not receive a comprehensive

ABR screen.

• Programs based solely on ALGO AABR technology are cost comparable to two-step

programs but are not at risk for missing infants with auditory neuropathy.2
