"The Hum" refers to a worldwide phenomenon of an unexplained, low-frequency humming, rumbling, or droning sound heard by a small percentage of the population but not by everyone. Described as similar to a car engine or a distant drill, the persistent noise is often worse at night and can cause physical symptoms like headaches, nausea, and insomnia. ---------------------------------------------------------------------- Instagram- https://www.instagram.com/amritpal_si...
