Forest Grove Sound Mystery

In February 2016, residents of Forest Grove, Oregon, began reporting a strange, high-pitched noise that echoed through the town, often at night. Witnesses described it as sounding like car brakes, a steam whistle, or a “mechanical scream,” and it would last anywhere from a few seconds to several minutes. Authorities received around 200 calls, and investigators checked gas lines, industrial equipment, and mapped reported locations but found no consistent source. By the end of the month, the sound suddenly stopped, and with no confirmed explanation, the case was closed.
