Laryngoscope 2022 May 14. Epub 2022 May 14.

Department of Otolaryngology - Head & Neck Surgery, The Ohio State Wexner Medical Center, Columbus, Ohio, USA.

Objectives: Existing cochlear implant (CI) outcomes research demonstrates a high degree of variability in device effectiveness among experienced CI users. Increasing evidence suggests that verbal learning and memory (VL&M) may have an influence on speech recognition with CIs. This study examined the relations in CI users between visual measures of VL&M and speech recognition in a series of models that also incorporated spectro-temporal discrimination. Read More

The dorsal cochlear nucleus (DCN) integrates auditory nerve input with nonauditory sensory signals and is proposed to function in sound source localization and suppression of self-generated sounds. The DCN also integrates activity from descending auditory pathways, including a particularly large feedback projection from the inferior colliculus (IC), the main ascending target of the DCN. Understanding how these descending feedback signals are integrated into the DCN circuit and what role they play in hearing requires knowing the targeted DCN cell types and their postsynaptic responses.

Am J Audiol 2022 Mar 20;31(1):112-125. Epub 2022 Jan 20.

Department of Physical Therapy, Speech-Language-Hearing Sciences, and Occupational Therapy, School of Medicine (FMUSP), University of São Paulo, SP, Brazil.

Purpose: This study evaluates the exposure of call center operators (CCOs) to occupational noise, its association with auditory and nonauditory symptoms, and the feasibility of monaural and binaural headsets.

Method: We measured the noise exposure sound pressure levels (SPLs) with the microphone-in-real-ear technique and administered a questionnaire on auditory/nonauditory symptoms and headset preference.

Results: We assessed 79 CCOs with normal hearing. Read More

Older adults often experience difficulties understanding speech in adverse listening conditions. It has been suggested that for listeners with normal and near-normal audiograms, these difficulties may, at least in part, arise from age-related cochlear synaptopathy. The aim of this study was to assess if performance on auditory tasks relying on temporal envelope processing reveal age-related deficits consistent with those expected from cochlear synaptopathy.

Otol Neurotol 2021 09;42(8):e1022-e1029

Westmead Hospital, Westmead, New South Wales.

Objective: The purpose of this study was to characterize a cohort of patients with nonauditory side-effects (NASx) following cochlear implant (CI) surgery.

Study Design: Retrospective case review.

Setting: Tertiary referral center. Read More
