A study from MacEwan University in Canada identifies low-frequency sound vibrations, known as infrasound, as a potential cause for feelings of unease in old buildings. These inaudible vibrations, produced by aging infrastructure and natural phenomena, can raise stress levels and alter moods without the occupants' awareness.
- 01Infrasound, below 20 hertz, can affect mood and stress levels.
- 02Old buildings often produce infrasound through aging pipes and ventilation systems.
- 03Participants exposed to infrasound reported increased irritability and stress.
- 04The study suggests a biological response to inaudible vibrations may explain feelings of unease.
- 05Further research is needed to explore different frequencies and their effects.

Research published in the journal *Frontiers in Behavioral Neuroscience* reveals that low-frequency sound vibrations, known as infrasound, may explain why old buildings feel unsettling. Infrasound, which is below the audible range of 20 hertz, can be produced by aging infrastructure like pipes and ventilation systems, as well as natural events such as storms and earthquakes. Rodney Schmaltz, a psychologist at MacEwan University in Canada, led the study, which involved 36 undergraduate students who listened to calming or unsettling music while being exposed to infrasound without their knowledge. Those exposed to infrasound reported feeling more irritable and uncomfortable, with a significant rise in cortisol levels, a hormone linked to stress. The researchers suggest that humans might be biologically predisposed to react negatively to these inaudible vibrations, similar to how some animals sense impending natural disasters. While the findings are promising, the authors note that the small sample size and limited frequency tested indicate a need for further research to explore the broader implications for building design and noise regulations.

Understanding the effects of infrasound could influence how buildings are designed and managed, potentially reducing feelings of discomfort in older structures.
