Paula Lynch tells KOIN she first heard the noise about two weeks ago. Since then, she's heard it four other times. Her neighbor has heard it three times.
Both Lynch and her neighbor, who asked that her name not be used, describe the sound as loud and like a warning alarm.
"It's hard to identify what angle its coming from because it just kind of encompasses the area," Lynch said. "We're just hoping somebody might be able to identify it so we can report it and have it stop happening."
Both the City of Forest Grove Public Works Department and Fire Department say they don't know where the noise is coming from. The fire department speculated the sound appeared to be some sort of air compressor, but said that crews would have to actually be in the neighborhood to identify the sound before making a determination.
A spokesperson with NW Natural said there have been no reports of any problems with the gas lines in the neighborhood. The spokesperson added that, while the company does have release valves, if gas were to be released, people would be able to smell it.
Lynch posted a recording she made of the video onto Facebook. It has been shared repeatedly.
Those who have heard the sound in person describe it as being extremely loud. Lynch said she has to cover her ear immediately to protect her hearing.
a thought on that particular phenomena as far as the particular case is concerned. Perhaps it's something akin to the noise that emanated from the World Trade Center one whilst it was under construction, one may recall it was the wind interacting with the unfinished structure. Perhaps it's a house or some other structure or natural object interacting with the wind.
