Sound frequencies below 20 Hz, called infrasounds, are not perceptible to humans. Some animals can perceive these frequencies and show an aversion to these sounds. Recent research suggests that these sounds may have adverse effects on humans, even though we cannot perceive them. A recent paper published in Frontiers in Behavioral Neuroscience examined the effect of infrasound exposure on subjective and objective measures in human participants in a controlled study. They found that infrasound was associated with elevated salivary cortisol and higher self-reported irritability, disinterest, and sadness appraisal. These findings emphasize the potential value of identifying and mitigating sources of infrasound pollution within our environments.
