The Windsor Hum and Sky Trumpets Explained

For nearly a decade, residents of Windsor, Ontario reported a low-frequency hum that disrupted sleep, rattled homes, and affected thousands of people. It was difficult to locate, impossible to ignore, and for years, no one could fully confirm where it was coming from.And then it stopped.In this episode of The Midnight Drive, we explore the Windsor Hum, a rare case where a widely reported unexplained sound was eventually traced to industrial activity across the U.S. border.From there, we move into a broader phenomenon often referred to as “sky trumpets” or skyquakes. These are sudden, metallic or booming sounds reported around the world, often described as coming from the sky with no visible source.Some of these events have plausible explanations. Others remain unclear or are complicated by misidentified sounds and altered recordings.This episode is not about proving a single answer. It is about understanding how sound behaves in the environment, how perception shapes experience, and what it feels like when something is present but difficult to locate.Topics covered: Windsor Hum infrasound Zug Island industrial activity low-frequency vibration sky trumpets skyquakes atmospheric sound propagation unexplained sound phenomena© Hondira LLC 2026
