Hidden Hearing Loss in Older Adults

Conditions studied: Hidden Hearing Loss

In brief

The goal of this observational study is to investigate whether speech-in-noise perception deficits in older adults aged 60 years or older with objectively normal hearing thresholds are due to impaired ability of processing temporal cues in speech signals. The study further aims to examine whether cognitive and cortical mechanisms provide compensatory support for speech perception in challenging listening environments.
