This study shows that deficits in extended high-frequency hearing reduce cortical response amplitudes to speech, even in young adults, and highlights the need to include EHF hearing in clinical assessments and hearing aid design.

The paper examines how aging and hearing impairment affect speech encoding and phoneme discrimination using EEG and behavioral tests, finding age-related declines in high-frequency envelope coding but preserved low-frequency encoding.

This study investigates age-dependent auditory profiles in tinnitus using electrophysiological and behavioral measures, finding distinct neural enhancements in young adults and degraded sensorineural function in middle-aged adults.

This study compares ABR, SAM EFR, and RAM EFR to predict cochlear synaptopathy in mice with varying outer hair cell dysfunction, finding RAM EFR best predicts broad synapse loss while ABR best predicts focal synaptopathy.

This study shows that age-related declines in neural phase-locking to both envelope and temporal fine structure, measured via FFRs, are linked to cochlear synaptopathy but not speech intelligibility.

This study investigates how cochlear synaptopathy affects speech intelligibility in older adults using an EEG-based marker and finds that CS contributes to speech coding deficits in noise beyond hearing sensitivity.

This study examines markers of hidden hearing loss in tinnitus patients and finds no difference between tinnitus and non-tinnitus groups but links low-pass speech-in-noise performance to tinnitus distress and hyperacusis.

The paper investigates how neural adaptation and processing speed affect speech comprehension, showing these factors are critical even when hearing thresholds and age are controlled for.

This study examines how age and hearing loss affect neural processing of phonemes, finding that temporal delay of EEG responses increases with age and high-frequency hearing loss, correlating with speech comprehension.

This study examines if recreational noise exposure alters biomarkers of cochlear synaptopathy, finding no significant changes except for a learning effect in speech audiometry.

The paper develops a DNN framework to model auditory sensory cells and synapses, improving simulation speed by 70-280 times.

This study develops an optimized stimulus envelope to enhance the sensitivity of envelope-following responses (EFRs) for detecting cochlear synaptopathy in humans through computational modeling and experimental validation.

This study examines if subcortical EEG metrics of synaptopathy, like ABRs and EFRs, are applicable to older adults with impaired audiograms, finding mixed results and interactions between hearing loss and age.

This study investigates how low- and high-frequency hearing deficits affect speech recognition in noise, finding that low-pass speech information strongly correlates with broadband performance and that high-pass speech encoding is noise-type invariant.

The paper examines the relationship between subcortical EEG responses and psychoacoustic tasks to understand the role of cochlear synaptopathy and gain loss in human hearing.
