Mystery Noise Forest Grove Oregon

[rdunk]

FOREST GROVE, Ore. — People living in a west Forest Grove neighborhood are puzzled by a high-pitched whistling noise.

Paula Lynch told KATU News she first heard the noise several weeks ago. She's heard the noise about five times, and at all hours of the day.

On Friday, she recorded a 30-second video and posted it to social media, hoping someone had an answer.

To me, that sounds very much like a malfunctioning severe weather siren.

Just saw this thread; after listening to the recording of the sound, it sounds to me like high pressure air escaping from an air brake system, usually thru a pinhole in a brake chamber diaphragm; this could be on a truck,or from a railroad car, since both have high pressure air brake systems
