Sound + pressure device eases stuffy ears and face pain in small trial

This study tested a handheld device called SinuSonic that uses gentle sound vibrations and breathing pressure to help people with Eustachian tube dysfunction (a condition where the ear's pressure-regulating tube doesn't work properly). Thirty adults used the device twice daily for six weeks. The goal was to see if it could reduce symptoms like ear pressure, clogging, popping, muffled hearing, and ringing. Results showed improvement in these symptoms over the treatment period.
