Loud High Pitched Noise In Oregon Is Still A Mystery

Downtown Forest Grove WikiMedia

Strange videos of a mysterious, high-pitched noise scaring Forest Grove residents has gone national. The high pitched has been happening for over a month and can be heard from blocks away. Members at AboveTopSecret.com have a proposed various hypothesis including: pressure leak, a drill, a home alarm, electronic feedback and President Obama blowing smoke up residents ass.

“It’s definitely a horrendous noise,” Dave Nemeyer, fire marshal of Forest Grove Fire and Rescue told ABC News. “I have no idea what the noise is. [The resident] described to us that it was coming from the middle of the street. To me, it sounds like the sound of train tracks, that metal screeching sound, but there are no train tracks near her home … so that’s obviously ruled out.”


KATU reported over the weekend an “experts” take on the noise.

We took the recording to audio expert Tobin Cooley, who measured it with a sound level meter. He said he gets plenty of calls for mysterious sounds, but this one is by far the most baffling.

“It sounds like some sort of pressurized gas or air through a fitting or valve or something,” Cooley said. “It’s not steady state and you can’t predict when it’s going to happen. Those are all interesting sound features.”

Cooley said he thinks the sound is originating near Gales Creek Road, as high-pitched tones don’t travel very far.

“The best instrument by far is the human ear,” he said. “If you can track it down and experience it, with measurements and your ears, you can find the source.”

A spokesperson for Northwest Natural Gas told me that it’s not a gas line, and they don’t have any relief valves in the area. They say a leaking line would sound like a tea kettle, and people would smell the gas.


Hopefully they’ll figure out what the noise is soon. So far officials have ruled out a water valve, gas leak and wildlife.
