Buzzing, droning sound late at night in N. County?

[Jami San]

February 2023. San Marcos Ca. Right around the college. Wow. I'm sorry you all were hearing/feeling this too, but I'm glad I'm not alone. Hopefully, the noise is gone for you.
I noticed this noise a couple of years ago. My husband doesn't hear it ,and I chose not to draw his attention to it as I don't want his life as miserable as mine with the noise. My daughter, who has super hearing, can barely perceive it, although she can accurately describe the sound when I ask her to listen. She can't believe that sound is bugging me.
I do have tinnitus. This sound is not at all like tinnitus. It is a deep drone. It vibrates through the body as if you were standing on top of a speaker playing bass and drums. It is very loud to me, especially when I lay my head sideways on my pillow. I have a split California king foam mattress and a foam pillow. I can't hear or feel it when my husband moves or gets out of bed. Yet, I hear the noise. I feel the noise. Deep, rumbling, pulsating droning.
The last few months it has gotten worse. At least to me. It is not just at night. In the day it is masked by traffic and other city noises but it is there. It wakes me with headaches especially around 3:30 and 4am. These headaches are quite bad. They come on fast and with every pulse the pain increases. If I try to walk around with the headache and the droning noise, hammering and vibrating my head, I can lose my balance.
I thought it might be the traffic from the freeway echoing off the hill but that doesn't seem the case. Also, I explored the possibility that it could be a neighbors air conditioning but it isnt that. It does seem to me to be machinery that is underground.
I can't explain why I seem to be really susceptible and sensitive to the noise while others barely notice it. It is hurting me and driving me crazy. Please post if you have found the source or KNOW what it is.

Old thread, but whatever.... Not saying this is people's imagination but maybe read this.

They've been doing military drills the past few days, maybe that's what you heard?

It's difficult to pinpoint the direction it's coming from. I live in the Lake San Marcos communities and with the twisting roads and the mountains directly behind us, sound tends to echo and reverberate. It seems distant and yet the buzzing/vibrating can almost be felt some nights. It sounds like a cross between a loud (but distant) propeller plane, a train slowly crossing tracks and some kind of industrial drilling. It has a definite and fairly consistent "pulse" of the sound reverberating which suggests to me it's something industrial on a regular timer/rhythm as opposed to something random.

So, firstly, anyone else in North San Diego County hearing this? Any theories as to what it might be? Something from Camp Pendleton? Some night-time construction? I'm sure you can tell from my post, but for the benefit of those who may read this years later, I'm posting this in May of 2016.

Probably a Chinese spy balloon, or drone.

Yep, I hear it too. I'm in Carlsbad, near S Melrose on border of San Marcos. I hear it most nights, some louder than others. Sometimes I don't hear it for a few days and hope it never comes back...but then it does. I am pretty close to an underground gas pipeline and wondering if it might be that. I've asked neighbors and they don't hear it; nor does my family. I read that 10% of people can hear these low tones (what Jami San describes above is what I hear too, very low hum that is intermittent - it starts and stops, low bass like when a car playing low music with windows closed is next to you.

Would love any insights and wondering who else is hearing this. If anyone wants to meet to discuss, perhaps the Starbucks on Melrose in Vista is near most of us, LOL!

I have been waking up at about 3-4 for the past few months. I can sit and listen to the humming. I can only describe it as a machine working. I can actually hear it bog down like it's working harder. It sounds like the trash truck on trash day but really far away. I'm in San Marcos Vista. I'm curious if it's he rock quarry near old twin oaks. I would not think they would be digging at this time. Or underground mining??
