I am so jazzed that Snow and Tall Trees have gotten together to track down the "Wrightwood Hum."  Now they just need a few more people that hear it to help map it. Joe Schmoe: You had some good ideas too. So, did other folks. It has to be some innocuous cause or there is an outbreak of tinnitus in WW. Have fun. If I lived closer I'd pitch in to help. And, do keep us all updated. cheryl o7o

There is a condition known as Low Frequency Tinnitus.  However, that several people in the same general location would have it at the same time is a somewhat remote possibility.  I do believe that the low frequency sound is present from time to time.  If I could get a recording of it, I would like to view the waveform on a scope and attempt to determine the approximate frequency.

Interesting interview with a geophysicist reminded me of this thread. Talking about various effects of acoustic waves bouncing off an inversion layer.  Which would support the idea that when the inversion layers moves over a certain part of town, noise from far off becomes distorted and amplified -- I still think that's the explanation.

The Wrightwood hum is back today since this morning after being absent for months.

Cardinal and Hwy 2.  Someone else mentioned to me yesterday that they were hearing the Wrightwood Hum at this same location.  Noise can be something that you never pay attention to until someone points it out.  Maybe this is what happened and after a few days I will forget and the noise will go away.

I can't tell you how disappointed I was when I moved to WW over a year ago and heard the constant hum at night when they were doing the road construction. I lived with the same sound in Riverside for over 12 years once the freeway construction started...24 hours a day, in addition to the house movement because of the constant heavy equipment being used: bang, bang, bang. I thought I'd "lose" the sound here, but no. At first I was told it was the snow making at Mt. High, or "Are you sure it isn't the pipes or appliances?" But it has the same pattern as what we endured down below and they are still going through that. I've concluded that, as the crow flies, the rock crushing and I-15 construction is not far off. And the way the sound carries up the pass and canyons it's a spit away. It's worse in the house than outside. There is far too much construction, all going on at the same time, on every major freeway. The sound, the constant hum, is very disruptive to me, and of course, worse at night because that's when the real road work is currently being done. Will we ever get a quiet night's sleep again?

I'm "bumping" this thread or conversation back up to the "front of the line", so we can get this conversation going again, because it was so far back in the timeline, it was disappearing...

Thanks, I believe I considered every definition of "bump" except that. Didn't occur to me. So, if a discussion goes stale & is not pursued, it just kind of "dies on the vine". A "bump" revives it. Thanks again!

I live on Snowbird and the other night as I was going to bed, I heard a humming sound.  I walked through my entire house and outside trying to isolate it, but finally gave up and went to bed.  Have not heard it again.  Now that I know others are hearing it, I will try to note dates and times.

Snowbird Street is about a mile from Cardinal Street and I heard the hum yesterday but not today.  Sagespirit like you it is louder inside the house than out side but this on and off again humming noise has been going on since I moved here well before any construction started in the Cajon Pass.

I wonder if it could be vibrations from the high pressure gas line that runs from  Phelan over the mountains north of Wrightwood and terminates near Rivera.

This happened last year same area. The people called a plumber and found out that it was a pressure regulator
at the well head. Once that was fixed the noise went away. Makes your pipes hum.

I think that it is a wandering didgeridoo player with too much time on her/his hands.

I haven't gone back through all the posts to see if water pipes have been listed as a possible cause.

Quote
A leaking water pipe generates noise (sound and vibration) which is transmitted for long distances both inside the pipe and in the soil close to the leak

Also these article are worth taking a look at:
