Clinical observation and application of multiple auditory steady-state response: MASTER

[Auditory steady-state response in the auditory evaluation: clinical application].

BACKGROUND the auditory steady state response (ASSR) is an electrophysiological procedure that evaluates, at the same time, the hearing thresholds of both ears at various frequencies. This procedure reduces the time of testing and enables the stimulation of levels close to 125dB HL, characterizing residual hearing. AIM to verify the applicability of the ASSR to determine the hearing threshold...

Clinical Application of Auditory Evoked Potentials in Infants: Comparing the Auditory Brainstem Response and Auditory Steady State Response

Auditory steady state response in auditory neuropathy.

REVIEW Auditory neuropathy is a disorder characterised by preservation of outer hair cell function, with normal otoacoustic emissions and/or cochlear microphonics, but an absent or distorted auditory brainstem response. PURPOSE This study aimed to objectively assess hearing thresholds in patients with auditory neuropathy, using the auditory steady state response. MATERIALS AND METHODS Thirt...

[Stopping criteria for averaging the multiple auditory steady-state response].

INTRODUCTION AND OBJECTIVES The aim of this study was to examine the efficiency of the averaging technique for estimating multiple auditory steady state responses in normal hearing subjects and to provide quantifiable stopping criteria at near-threshold intensities. METHODS Multiple amplitude-modulated (89-115 Hz) tones (500, 1,000, 2,000 and 4,000 Hz) were simultaneously presented to both ea...

Clinical Comparison of the Auditory Steady-State Response with the Click Auditory Brainstem Response in Infants

OBJECTIVES Our goal was to determine the effectiveness of using the auditory steady state response (ASSR) as a measure of hearing thresholds in infants who are suspected of having significant hearing loss, as compared with using the click-auditory brainstem response (C-ABR). METHODS We retrospectively analyzed the audiologic profiles of 76 infants (46 boys and 30 girls, a total of 151 ears) w...
