Biomarkers of brain function may lead to clinical tests for hidden hearing loss

A pair of biomarkers of brain function — one that represents ‘listening effort,’ and another that measures ability to process rapid changes in frequencies — may help to explain why a person with normal hearing may struggle to follow conversations in noisy environments. The researchers hoped the study could inform the design of next-generation clinical testing for hidden hearing loss, a condition that cannot currently be measured using standard hearing exams.
