The Hum May Begin Inside the Listener
Tests of 28 people who hear a persistent low tone found little evidence for exceptional hearing or measurable sound emitted by the ear.
Summary
Tests of 28 people who hear a persistent low tone found little evidence for exceptional hearing or measurable sound emitted by the ear.
Norwegian University of Science and Technology researchers examined 28 German participants who report hearing the low-frequency phenomenon called the Hum. Most did not have unusually sensitive low-frequency hearing, and measurements did not support the idea that their ears were physically emitting the sound. The authors say low-frequency tinnitus is the strongest remaining explanation. The study is small and does not rule out external noise sources in every case or identify a single mechanism for all listeners.
