How hearing differences affect sound perception as we age

Official title: Effects of asymmetries on binaural-hearing abilities across the lifespan

Funded at Univ of Maryland, College Park · NIH-11061113 · Data updated 2026-11-12

This study looks at how having different hearing abilities in each ear affects older adults' ability to understand speech in noisy places, helping us learn more about the challenges they face as they age.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults aged 65 and above who experience varying degrees of hearing loss and asymmetries in their hearing abilities.

Less likely to help

Patients under 21 years old or those with normal hearing without any asymmetries may not benefit from this research.

What this research studies

This research investigates how differences in hearing ability between the two ears impact the ability to understand speech in noisy environments, particularly as people age. It focuses on older adults, especially those over 65, who may experience hearing loss and asymmetries in their hearing thresholds. By collecting data from a diverse group of participants, the study aims to uncover the relationship between age, hearing asymmetries, and challenges in speech perception. Advanced machine learning techniques will be employed to analyze the data and generate new insights into these auditory processes.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for helping older adults better understand speech in noisy settings.

How similar studies have gone: Previous research has shown that understanding binaural hearing can significantly impact auditory processing, suggesting that this approach may yield valuable insights.
