Hearing evaluation was done by ABR and
ASSR under natural sleep or sedation (by chloral hydrate) in a purpose build sound treated room.
However, the results of auditory steady-state response (
ASSR) tests are not described fully in most previous reports.
The
ASSR can be searched by air and bone pathways, and it is possible to determine the presence and magnitude of conductive impairment by means of the difference between the minimum levels of air-bone response, which makes it a useful tool in the assessment of conductive impairment, one of the main pathologies in infants [5].
In this article, we describe our case series in which we assessed the relative contributions of auditory brainstem response (ABR) testing and auditory steady-state response (
ASSR) testing in facilitating appropriate hearing aid fitting for hearing-impaired children in whom behavioral audiometry was difficult or unreliable.

These mechanisms may account for the observation in normal hearing humans that auditory tasks that require top-down attention increase not only the amplitude of the
ASSR localizing to A1, but also the amplitude of the N1 transient response whose cortical sources localize to secondary auditory cortex (A2) in the region of the planum temporale [7, 18].
Auditory steady-state response (
ASSR) audiometry is a commercially available tool that is used to predict behavioral auditory threshold levels.
