Did you know your cells can “hear”?
A 2025 study from Kyoto University shows that exposing cells to sound waves changes how they behave — even turning off the process that makes fat cells grow.
Researchers exposed cultured cells to audible sound waves (like 440 Hz, 14 kHz, and white noise) and found that over 190 genes reacted, changing how cells behave.
Key findings:
42 genes changed expression after 2 hours, 145 after 24 hours
One gene (Ptgs2 / COX-2) linked sound to biochemical pathways
Sound stimulation suppressed fat cell differentiation (preadipocytes → adipocytes)
Changes were also seen in cell adhesion (how cells attach to surfaces)
This suggests that sound is more than a sensory phenomenon — it may act as a non-invasive cellular stimulator, opening new possibilities in medicine and wellbeing.
--> Could sound one day be used as medicine?
