Predicting neural deficits in sensorineural hearing loss from word recognition scores.

Sci Rep 2022 Jun 23;12(1):8929. Epub 2022 Jun 23.

Eaton-Peabody Laboratories, Massachusetts Eye & Ear, 243 Charles Street, Boston, MA, 02114-3096, USA.

The current gold standard of clinical hearing assessment includes a pure-tone audiogram combined with a word recognition task. This retrospective study tests the hypothesis that deficits in word recognition that cannot be explained by loss in audibility or cognition may reflect underlying cochlear nerve degeneration (CND). We collected the audiological data of nearly 96,000 ears from patients with normal hearing, conductive hearing loss (CHL) and a variety of sensorineural etiologies including (1) age-related hearing loss (ARHL); (2) neuropathy related to vestibular schwannoma or neurofibromatosis of type 2; (3) Ménière's disease; (4) sudden sensorineural hearing loss (SSNHL), (5) exposure to ototoxic drugs (carboplatin and/or cisplatin, vancomycin or gentamicin) or (6) noise damage including those with a 4-kHz "noise notch" or reporting occupational or recreational noise exposure.

Sleep affects higher-level categorization of speech sounds, but not frequency encoding.

Cortex 2022 May 31;154:27-45. Epub 2022 May 31.

Department of Psychology, Concordia University, Montreal, QC, Canada. Electronic address:

Sleep can increase consolidation of new knowledge and skills. It is less clear whether sleep plays a role in other aspects of experience-dependent neuroplasticity, which underlie important human capabilities such as spoken language processing. Theories of sensory learning differ in their predictions; some imply rapid learning at early sensory levels, while other propose a slow, progressive timecourse such that higher-level categorical representations guide immediate, novice learning, while lower-level sensory changes do not emerge until later stages.
