A Scientific Inquiry into the Source of the Worldwide Hum

Most people find this website because they are searching for the source of an unusual low frequency sound called the Worldwide Hum. The classic description is that it sounds like there is a truck idling outside your home. For some people, it is a deep and distant droning bass tone. Some people perceive the sound as a rumbling noise. The sound is louder indoors than outdoors, and louder late at night than during the day. It can suddenly appear or dissappear for days or months. People of all ages can be affected, although the incidence among children is very low. In the more serious cases, the Hum can affect quality of life; in a number of documented cases, the torment of the noise has been life-altering. To date, more than 10000 people have entered their locations and data.

This website aims to document for research purposes the locations and self-reported data on this phenomenon. Moreover, we are fundraising to conduct some critical experiments that will point to the source of the Hum. This is a scientific investigation, and not a place for wild speculation or pseudoscience.
