DSGZ Study Ties Global 'The Hum' to Low-Frequency Tinnitus in 28-Volunteer Test

Summary
A DSGZ-led study argues many cases of the long-reported global “Hum” may stem from low-frequency tinnitus rather than an external sound source.
Tests on 28 volunteers found most did not have unusually strong low-frequency hearing, weakening one leading theory that Hum hearers are simply extra sensitive to bass sounds.
Ear-canal measurements also found no unusual otoacoustic emissions, undercutting the idea that inner-ear sounds themselves explain the phenomenon and pointing instead to a subjective auditory perception.
The researchers said that would not explain every case, and some measurable external low-frequency sounds may still exist, but the findings shift attention toward the auditory system.
For people who hear the Hum, reclassifying some cases as tinnitus could connect them to existing coping tools and treatment research for a condition with no cure yet.
