{"doi":"10.1063/5.0189528","title":"The effect of broadband elicitor duration on transient-evoked otoacoustic emissions and a psychoacoustic measure of gain reduction","abstract":"Physiological and psychoacoustic studies of the medial olivocochlear reflex (MOCR) in humans have often relied on long elicitors (> 100-ms). This is largely due to previous research using otoacoustic emissions (OAEs) that found multiple MOCR time constants, including time constants in the 100s of milliseconds, when elicited by broadband noise. However, the effect of the duration of broadband noise elicitors on similar psychoacoustic tasks is currently unknown. Additionally, the relationship between gain reduction measured psychoacoustically and using OAEs as a function of elicitor duration are unknown. The current study measured the effects of ipsilateral broadband noise elicitor duration on transient-evoked OAEs (TEOAEs) and psychoacoustic gain reduction estimated from a forward-masking paradigm. Changes in the TEOAE were measured in terms of magnitude and phase. When phase was accounted for in the TEOAEs, the time constants were relatively short (∼53 ms) and were very similar to the psychoacoustic time constants (∼60 ms). When only changes in TEOAE magnitude were measured, and phase was omitted, the average time constant were longer (∼97 ms). Overall, the psychoacoustic and physiological data in the study were consistent with the time course of gain reduction by the MOCR. Near-maximal MOCR effects can be measured with ipsilateral broadband elicitor durations of 200 ms or less in a forward-masking paradigm.","journal":"AIP conference proceedings","year":2024,"id":486784,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9576,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":369688,"name":"Kristen J.
