A new study published in PLOS One offers what researchers say is the most evidence-supported explanation yet for “The Hum” — an unexplained low-frequency droning reported by people around the world — pointing to subjective tinnitus in the low-frequency range as the likely culprit for most sufferers....
Audiologists assessing patients who report unexplained low-frequency environmental sounds should consider low-frequency tinnitus as a primary diagnosis before attributing symptoms to external causes; standard tinnitus evaluation protocols are appropriate.
Reframing 'The Hum' as low-frequency tinnitus could redirect affected individuals toward evidence-based audiological assessment and tinnitus management rather than years of fruitless environmental investigation.
- 01PLOS One study proposes 'The Hum' is subjective low-frequency tinnitus, not an external acoustic phenomenon.
- 02The Hum is a globally reported complaint of a persistent low-frequency droning with no confirmed external source.
- 03Low-frequency tinnitus is under-recognised and can be diagnostically distinct from high-frequency tinnitus presentations.
- 04Reclassification has implications for how patients are assessed and counselled in audiology clinics.
- 05Findings are observational/theoretical; no large controlled trial has confirmed the tinnitus mechanism.
'The Hum' is most likely caused by subjective tinnitus in the low-frequency range.
