— “The metallic scraping sound was menacing, foreboding, a screeching unrelenting assault on the auditory senses. All I can say is that the sound seemed like some kind of warning.”

– Earwitness, Sault Ste. Marie, Ontario, Canada

— “We heard this horrible metallic, scraping, synthesizer sound over the  music we were listening to. ...Although we could see nothing, we could  hear and feel something massive rising from the canyon below until it was directly above our heads.”

July 14, 2014  Albuquerque, New Mexico - Since the current cycle of strange sounds around the world began in early 2011, perhaps the oddest is the metallic scraping, trumpet sounds or metallic humming that have been reported throughout North America and even one loud pulsing hum event linked to aerial diamond-shaped craft over Tangshan City, Hebei Province, China, in September 2011.

— “If you had a snowplow going down a dry street and you had this loud sound of scraping metal against concrete, almost like a squealing as it’s scraping.”

- Pattie, Univ. of Michigan, Ann Arbor

— “All of a sudden I heard an extremely loud screeching noise. It sounded like a 10,000-gallon steel drum being drug over a bed or rocks.”

June 26, 2014 - Since the phenomenon of strange sounds around the world began in early 2011, perhaps the oddest is the metallic scraping or trumpet sounds. Recently on June 18, 2014, an administrative assistant in the University of Michigan Health System in Ann Arbor arrived home from work in the early afternoon before a thunderstorm. She has asked me to call her Pattie. Upstairs her partner was working and across the street a neighbor was home. All three heard a loud, metallic scraping sound seeming to come from the sky that lasted for several seconds. Pattie compares the mysterious sound to “a snowplow going down a dry street ... almost like a squealing as it's scraping.”
