Scientists find infrasound frequencies linked to unsettling feelings and stress

A recent study published in Frontiers in Behavioral Neuroscience investigated the effects of infrasound, frequencies below 20 hertz, on human mood and stress levels. Researchers exposed 36 volunteers to music with and without infrasound, measuring their subjective feelings and cortisol levels. The findings indicated that infrasound exposure led to increased stress and negative subjective experiences, even though participants could not consciously detect its presence. Scientists speculate that this aversion may be an evolutionary response to natural disasters, but also suggest infrasound could explain unsettling feelings in supposedly haunted locations due to noise pollution.
