You are not alone. For decades, many have heard this noise, called The Hum. It is usually described as a low rumble, like an external diesel-powered machine in the distance. Conversely, many hear the low murmur internally. The steady drone is not just an irritant for people but affects their daily functioning. The Hum can be hazardous, often creating distress and contributing to a loss of sleep. The danger level ranges from a minor irritant all the way to suicide.
