- The Worldwide Hum is an unusual low-frequency sound heard by 2-4% of the global population, often described as a car engine idling or a low rumbling, louder at night and indoors.
- Sufferers hear the Hum wherever they go, while others nearby cannot; it may be an internal otoacoustic phenomenon generated by the brain or auditory organs.
- Some sufferers have hyperacusis (exceptionally sensitive hearing) and perceive actual environmental noises; the project provides tools to distinguish between internal and external sources.
- The project is a non-profit, volunteer effort that maps self-reported data, hosts scientific investigations, and explicitly excludes pseudoscience or conspiracy theories.
- Contact and fundraising barely cover costs; Dr. MacPherson (glen.macpherson@gmail.com) may not be able to reply to all emails.
