	(AABR) uses a stimulus which is delivered through earphones and detected by scalp electrodes. The test takes between 8 to 20 minutes and has a sensitivity 96-99%. The basis of a neonatal hearing test that uses a trigger stimulus delivered through earphones and subsequent brain electrical activity then detected by scalp electrodes. Then by computer analysis, averaging all the electrical activity following the trigger, peaks emerge reflecting signal passage activity through brain stem nuclei in the hearing central neural pathway~~. The infant test takes between 8 to 20 minutes, has a sensitivity 96-99%, and unlike other childhood auditory testing does not require a subject response~~.

	An increased absolute latency has been seen to occur in premature infants ({{preterm birth}}) related to decreased ~~myelinization~~ affecting the electrical conduction delays up to the brainstem.		An increased absolute latency has been seen to occur in premature infants ({{preterm birth}}) related to the decreased {{myelination}} affecting the electrical conduction delays up to the brainstem.

	Waves '''I''' and '''II''' - arise ipsilaterally to the stimulus and reflect the action potential of the auditory nerve.		Waves '''I''' and '''II''' - arise ipsilaterally to the stimulus and reflect the action potential of the auditory nerve.
