Tips & Tricks for Hearing Evaluation using Next Generation Auditory Steady-state Response Testing

چکیده

要旨: 聴性誘発反応 (evoked response auditory: ERA) を用いた聴力評価は, 小児から成人まで年齢に関係なく検査が可能である。日常臨床においては主に聴性定常反応 (auditory steady-state response: ASSR) と聴性脳幹反応 brainstem ABR) を用いて, 遊戯聴力検査や純音聴力検査といった心理学的検査では評価が困難な乳幼児や機能性難聴の聴力評価に用いられている。ASSR は 500Hz や 1000Hz といったクリック音刺激による聴性脳幹反応では評価困難であった周波数帯域の聴力の推定も可能であることから有用性が高い検査である。近年市販化された周波数掃引音の一つである chirp 音刺激による ASSR は次世代型 と呼ばれており, その有用性に関する報告が散見されている。本稿では実際に次世代型 を用いて検査を行っている言語聴覚士の立場から条件設定, 検査の注意点, 聴力レベルの推定などといった日常臨床に関する手技やコツについて概説する。

[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...

Steady state auditory evoked potentials in normal hearing subjects: evaluation of threshold and testing time.

BACKGROUND Steady state responses (SSRs), between 75 and 110 Hz, evoked by auditory amplitude modulated single or multiple tone stimuli, may be used to estimate objective hearing threshold. METHODS The aim of this study was to compare SSRs and click-evoked auditory brainstem responses (ABRs) in both ears of 20 adults (10 males and 10 females, aged between 24 and 36 years) with normal hearing ...

Hearing threshold estimation in infants using auditory steady-state responses.

Successful early intervention in children with permanent hearing loss requires assessment techniques that can accurately reflect the behavioral audiogram in infancy. This retrospective study compared auditory steady-state response (ASSR) findings from subjects tested in the first three months of life with subsequently obtained behavioral hearing levels. ASSR audiograms were established using am...

Sensitivity and specificity of auditory steady‐state response testing

INTRODUCTION The ASSR test is an electrophysiological test that evaluates, among other aspects, neural synchrony, based on the frequency or amplitude modulation of tones. OBJECTIVE The aim of this study was to determine the sensitivity and specificity of auditory steady-state response testing in detecting lesions and dysfunctions of the central auditory nervous system. METHODS Seventy volun...

Auditory sensitivity in children using the auditory steady-state response.

OBJECTIVE To determine the effectiveness of auditory steady-state response (ASSR) as a measure of hearing sensitivity in young children suspect for significant hearing loss. DESIGN Within-subject comparisons of click auditory brainstem response (ABR) thresholds and ASSR thresholds. SUBJECTS The study population comprised 42 children suspect for hearing loss and subsequently referred for hea...
