Anhelina Bilokon, AuD, a PhD candidate at the University of Maryland, presented findings this week at the 190th Meeting of the Acoustical Society of America showing that standard hearing tests miss something fundamental: sex-dependent hormonal changes alter how ears work. Emerging research suggests the field hasn't fully accounted for that yet.
Why it matters
For decades, medical research defaulted to male subjects, then applied the findings to everyone. Hearing science did the same thing. So, what are the baselines we use to diagnose hearing loss? Built largely on data collected from male subjects, then applied broadly.
Recognizing that gap is an opportunity to improve how hearing loss gets caught, managed, and treated.
The big picture
Men's and women's hearing changes differently over time.
- Men: earlier onset of decline, but gradual
- Women: monthly fluctuations tied to the menstrual cycle, then sharp changes at menopause.
Hormones act on the brain structures that process sound. Small shifts in hormone levels change how those structures function. As a result, menopause warrants attention as an auditory risk window, alongside its better-known effects on bone density and cardiovascular health.
A closer look
Bilokon's research reanalyzes existing auditory data rather than running new trials. She's tracking how auditory processes change over time and interact with biologically significant events.
Standard hearing tests take a snapshot. They measure a threshold at a single point in time, without tracking how hormonal fluctuations might shift that baseline.
The challenge
The field knows sex-difference guidelines exist based on research in related fields. Bilokon argues that hearing science can adopt those frameworks now, without waiting for entirely new research infrastructure.
The bottom line
"By simply recognizing real biological differences, we can shift our scientific approach toward more accurate diagnoses and better care." —Dr. Bilokon
This applies to men, too. Understanding sex-specific auditory patterns produces better baselines for everyone. Tools built on broader, more representative data will serve everyone better.
Two areas where the research points toward refinement:
- Factoring in menstrual cycle phase when establishing hearing baselines for women of reproductive age
- Treating menopause as a prompt for proactive auditory screening, alongside standard age-based protocols
The science to do this better already exists.
