Shruti Haasan calls it a wrap on Salaar with Prabhas

Highlights

• Researchers say low-frequency infrasound may explain why some locations feel “haunted”
• A new study found exposure to the sound increased stress levels in participants
• Volunteers could not hear the frequency but still showed physical stress responses
• Scientists believe the findings could reshape how paranormal experiences are understood

The science behind a feeling many people struggle to explain

People visiting allegedly haunted locations often describe a similar experience. They feel uneasy, unsettled and deeply uncomfortable, even when there appears to be no obvious reason why. For years, these reactions have fuelled stories about ghosts, spirits and supernatural activity. Scientists are now offering a very different explanation, and it begins with a sound humans cannot even hear.

A new study published in Frontiers in Behavioral Neuroscience suggests that infrasound, which refers to acoustic frequencies below 20 hertz, may be responsible for triggering feelings often associated with paranormal encounters. Although the human ear cannot detect these frequencies, researchers found that the body may still respond to them in significant ways.
