The findings suggest that while humans cannot consciously detect infrasound, the body still registers it in some way. The exact biological mechanism remains unknown. Researchers also note the possibility that long-term exposure could influence health by keeping cortisol levels elevated and contributing to ongoing irritability or low mood.

"Increased cortisol levels help the body respond to immediate stressors by inducing a state of vigilance," said Prof Trevor Hamilton of MacEwan University, corresponding author. "This is an evolutionarily-adapted response that helps us in many situations. However, prolonged cortisol release is not a good thing. It can lead to a variety of physiological conditions and alter mental health."

Because the study included a relatively small group, the researchers performed additional analyses to confirm their findings. These checks showed the experiment was capable of detecting moderate to large effects, including the changes observed. Still, larger and more diverse studies will be needed to fully understand how infrasound shapes human emotions and behavior.

"This study was in many ways a first step towards understanding the effects of infrasound on humans," cautioned Scatterty. "So far, we've only tested a specific frequency. There could be many more frequencies and combinations that have their own differential effects. We also only collected subjective reports of how the participants felt after exposure, without directly observing their responses during the trial."

"The first priority would be testing a wider range of frequencies and exposure durations," added Schmaltz. "Infrasound in real environments is rarely a single clean tone, and we don't yet know how different frequencies or combinations affect mood and physiology. If those patterns become clearer, the findings could eventually inform noise regulations or building design standards. As someone who studies pseudoscience and misinformation, what stands out to me is that infrasound produces real, measurable reactions without any visible or audible source.
