Researchers Uncover New Complexities in Human Hearing
Researchers identified a previously unknown set of cochlear modes that refine our understanding of how the human ear assesses sounds.

Speech sounds elicit comparable neural responses and stimulate the same region in the brain of humans, macaques, and guinea pigs, a multidisciplinary group of University of Pittsburgh researchers reported in the journal “eNeuro.” The finding could help pave the way for better understanding and diagnosis of auditory processing deficits.
Published in “Ear and Hearing” the paper presents a new method for the prediction of speech perception for individual recipients, providing a methodology that could make patient trials more efficient, potentially leading to implants that are personalized to an individual’s listening capability.
Their results, published in the journal “eNeuro,” show that the filtering begins at the very beginning of the auditory stimuli processing, ie, in the brainstem. This finding runs counter to earlier hypotheses, which held that it was a function of the frontal cortex control, which is heavily impacted in schizophrenics.

Read MoreChildren with Tourette syndrome (TS) may process aspects of language faster than other children, a new study shows. Kids with TS, a neurological tic disorder, are faster at assembling sounds into words – the part of language called phonology – than typically developing children.
Read MoreThe type of sound processing that modern hearings aids provide to make speech more understandable may also make music enjoyment more difficult, according to a new study by the University of Colorado Boulder. The findings, suggest that less sophisticated hearing aids might actually be more compatible with listening to music, especially recorded music that has been processed.
