Multiple-ASSR Interactions in Adults with Sensorineural Hearing Loss

Abstract

The multiple auditory steady-state response (multiple-ASSR) technique, where thresholds for up to 8 frequencies (4 in each ear) are obtained simultaneously, is currently of great interest for audiometric assessment of infants. Although threshold estimates using the multiple-ASSR appear to be reasonably accurate, it is not currently known whether it is more efficient to use multiple stimuli or single stimuli when testing individuals with sensorineural hearing loss (SNHL). The current study investigated the effect of single versus multiple simultaneous stimuli on the 80- and 40-Hz ASSRs in adults with normal hearing or SNHL. Results showed significant interactions (i.e., decreased amplitudes) for both ASSRs going from single to multiple stimuli in one ear. Going from multiple one ear to multiple two ears did not further reduce the amplitude of the 80-Hz ASSR. At the 40-Hz rate, however, there was a further amplitude decrease going from one-ear multiple to two-ear multiple stimuli. Importantly, these interactions did not differ between the normal-hearing and SNHL groups. Although supportive of the multiple-ASSR technique, there are likely situations where it is more efficient to use single stimuli. Future studies are required to assess these interactions in infants with varying degrees and configurations of hearing loss.

A novel stimulus paradigm for simultaneous recording of monaural and binaural frequency following response for identification of binaural interaction component

“…Simultaneous recording of monaural and binaural FFR could be beneficial for assessing binaural processing at the neural level (e.g., binaural interaction component). In consonance with findings of the present study, few investigations have demonstrated that auditory evoked potentials can be recorded from both ears simultaneously in the same recording using suitable stimulus presentation paradigms (Maruthy et al, 2019;John et al, 1998;Ishida & Stapells, 2012). Recently, Maruthy et al…”

“…Further, results showed that the click ABR of both ears obtained using novel stimulus paradigm was comparable to click ABR elicited using the conventional method. Ishida and Stapells (2012) recorded 40 Hz and 80 Hz ASSR using multiple stimuli presented simultaneously to one ear or both ears and showed that ASSR could be recorded from both ears simultaneously in the same recording. The amplitude of 80 Hz ASSR recorded by presenting multiple stimuli to both ears was similar to multiple stimuli to one ear condition.…”

Evaluation of Speech-Evoked Envelope Following Responses as an Objective Aided Outcome Measure

“…11) were unexplained by the carrier spectrum. Higher stimulus levels lead to increased interactions, likely due to broader regions of activation in the cochlea (John et al 1998Ishida & Stapells 2012;McNerney & Burkard 2012). However, in contrast to the results seen in adults with normal hearing, the response amplitude for /i/ F1 decreases with further increase in stimulus bandwidth (response amplitude increased significantly from the LPF2k to LPF4k condition in normal hearing adults).…”

Intraoperative auditory steady-state monitoring during surgery in the cerebellopontine angle for estimation of postoperative hearing classes

“…Epochs with amplitudes exceeding 40 mV after bandpass filtering between 30 and 300 Hz were rejected, corresponding to values in the literature, ranging from approximately 30 to 60 mV. 20,42 The remaining epochs were pooled for further analysis, which are addressed as raw epochs in the remainder of this article.…”
