The book argues that a single cause may be unlikely; instead, a combination of factors contributes to the reported experiences, varying by location. Individual auditory sensitivity plays a key role in perception, with some people more susceptible to low-frequency sounds. Did you know that infrasound, sound below the range of human hearing, can still be perceived by the body?
The book progresses systematically, beginning with the history of Taos Hum reports and initial scientific responses. It then delves into acoustic properties, auditory perception, and potential environmental and technological origins, such as industrial activity or geophysical phenomena. Case studies and scientific data are presented, offering a nuanced perspective and potential mitigation strategies. The book's interdisciplinary approach is vital for holistically understanding this elusive environmental acoustics puzzle.
