Summary

This trial tests whether a non-invasive cooling device worn like a headband can protect the inner ear from noise-induced hearing loss. Firefighters will use the device for 30 minutes immediately after their shifts over a year. Researchers will compare hearing outcomes between those who receive the cooling therapy, a sham device, and no treatment.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
a headband-style device that delivers mild cooling to the inner ear
What this could lead to
If it works, this could offer a simple, non-invasive way to prevent noise-induced hearing loss in people with high occupational noise exposure.
What could go wrong
This is an early-stage trial testing safety and best duration, so the cooling approach may not provide meaningful protection. The device must also be practical for real-world use.
