The Auditory Brainstem Response (ABR) and the Cortical Auditory-Evoked Potential (CAEP) are auditory-evoked potentials used in the objective diagnosis of hearing loss and validation of paediatric amplification. They are far-field responses, meaning their acquisition can be time consuming complete due to their low signal-to-noise ratio, and therefore the larger number of response averages required for a clear response signal. A recent study of people with normal hearing discovered that eliciting the ABR using interleaved stimulation yields reliable results in half the time it takes to test each ear with typical sequential monaural stimulation (Bencito, 2020). The current study extends this work by exploring the efficacy of interleaved ABR and CAEPs in adults as compared with conventional monaural testing with a slow rate and monaural testing with a fast rate, with the underlying assumption that neural fatigue occurs in the peripheral auditory pathway, and therefore does not occur with bilateral interleaved stimulation. A total of 44 participants (27 females, 17 males) aged 18 to 63 years (M = 33, SD = 9.2) with symmetrical normal to mild sensorineural hearing loss underwent AEP testing under three conditions: interleaved, monaural slow and monaural fast. The measures for this study were Fsp, wave V latency and amplitude for click-evoked ABR, and the latency and amplitude of the P1-N1-P2 complex for 1 kHz tone-burst CAEP. Latency results showed no significant differences between the monaural slow and interleaved conditions, but significantly longer latencies in the monaural fast condition, for both ABR and CAEP testing. Fsp and amplitude measures revealed no significant difference for the ABR wave V and the CAEP P1 between the interleaved and monaural slow conditions. However, the P1-N1 and N1-P2 amplitudes and Fsp data for CAEP were significantly larger in the monaural slow condition as compared to the interleaved condition. Overall, these results support the efficacy of the interleaved technique for ABR testing, with potential benefits for CAEP as well, pending further exploration.
