For a long time, medical research tended to generalize to women results obtained mainly in men. But this approach is increasingly being called into question.
In the field of hearing, new research presented at the 190th Congress of the American Acoustics Society highlights important biological differences between the sexes. According to the work of Anhelina Bilokon, from the University of Maryland, hormones play a major role in the way our brain processes sounds.
Hormones directly influence hearing
Hearing is a particularly sensitive system. According to Anhelina Bilokon, even slight hormonal variations can alter the mechanisms involved in sound processing.
The researcher explains that when hormone levels change or fluctuate, the structures and processes underlying hearing can also change. This biological sensitivity could explain certain differences observed between men and women during hearing tests.
The data analyzed shows in particular that men generally experience earlier and progressive hearing decline. In women, the situation is different: hearing can vary during the menstrual cycle and undergo more marked changes at the time of menopause.
These observations confirm that hearing is not an isolated phenomenon, but is closely linked to other aspects of human health.
More precise diagnoses thanks to a personalized approach
Anhelina Bilokon’s work is not limited to measuring hearing acuity. They also seek to understand how hearing abilities evolve over time and interact with different biological events.
For the researcher, these variations are essential in order to more precisely identify the markers of hearing decline. She therefore encourages the scientific community to further integrate sex-related differences and hormonal effects into future studies.
This approach could make it possible to develop more adapted and more consistent evaluation methods between laboratories, based on recommendations already used in other areas of research.
A breakthrough that concerns everyone
At first glance, these results seem to fill a gap in knowledge regarding women’s health. However, their scope is much broader.
The stated objective is to improve the overall understanding of hearing in order to offer more precise diagnoses and care better suited to each individual. By taking into account real biological differences, health professionals could ultimately better prevent, detect and manage hearing disorders.
As Anhelina Bilokon points out, this research aims above all to improve the understanding of hearing for all, by promoting more personalized medicine based on the biological characteristics of each person.
