About this trial
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.

Trial outcomes
Primary outcomes
1
Conventional pure-tone audiometry (PTA) with extended high-frequency (0.25-16 kHz)
This measure reflects the overall audibility of the individual. Together with the other measures listed under the primary outcome measure, it provides a comprehensive assessment of participants' peripheral auditory function.
Time frame
Participants will complete all study assessments within one month of enrollment.2
Gap Detection Test (GDT)
This behavioral test assesses an individual's ability to detect brief silent gaps in an auditory signal, reflecting temporal resolution within the auditory system
Time frame
Participants will complete all study assessments within one month of enrollment.3
Distortion Product Otoacoustic Emissions (DPOAEs)
This objective measure evaluates cochlear outer hair cell. Together with the other measures listed under the primary outcome measure, it provides a comprehensive assessment of participants' peripheral auditory function.
Time frame
Participants will complete all study assessments within one month of enrollment.4
Electrocochleography
This objective measure assesses cochlear and auditory nerve function. Together with the other measures listed under the primary outcome measure, it provides a comprehensive assessment of participants' peripheral auditory function.
Time frame
Participants will complete all study assessments within one month of enrollment.Secondary outcomes
1
Depressive symptoms assessed using the Patient Health Questionnaire-9 (PHQ-9)
Time frame
Participants will complete all study assessments within one month of enrollment2
Anxiety symptoms assessed using the Generalized Anxiety Disorder-7 (GAD-7)
Time frame
Participants will complete all study assessments within one month of enrollment.3
Cognitive function assessed using Digit Span test.
Time frame
Participants will complete all study assessments within one month of enrollment.Sponsors and contacts
