Does anyone else's house hum on Tuesdays?
Every Tuesday morning, starting around 6:30 AM and lasting until roughly 9, our house hums. Low, constant vibration through the floor. Not the pipes, not the appliances. I've turned everything off, shut the water main, pulled the breaker. Still hums. Only Tuesdays. We're on the 200 block of Fellridge, been here two years. First year I thought it was construction somewhere. It is not construction. Construction does not keep a weekly schedule and it does not vibrate in B flat. Is this a Pellwick thing?
It's a Pellwick thing. Specifically a Fellridge thing. The whole stretch from the 100 to the 400 block does it. I've been here nine years. It has been doing this the entire time. I had an acoustic engineer come out once and he confirmed the frequency (B flat, you're correct, nice ear) and said the vibration was coming from the foundation, not through it. He said the house itself was producing the sound. I asked him why. He said "I'm an acoustic engineer, not a geologist. Or a priest."
The foundation is PRODUCING the sound? Not transmitting something from underground? Has anyone contacted the city?
The city is aware. They classify it as a "recurring environmental feature" and it's actually disclosed in property transactions for the Fellridge blocks. It was probably in your purchase documents. Page 40-something, buried in the Environmental Disclosures appendix, one line: "Property is located within the Fellridge Resonance Zone. Periodic low-frequency vibration may occur." May. That's doing a lot of heavy lifting for something that happens every single Tuesday like clockwork.
I'll add that it used to be Thursdays. Shifted to Tuesdays about fifteen years ago with no announcement, no explanation, and no acknowledgment from the city that anything changed. I went to a town meeting and asked about it. The person at the microphone said "the schedule was updated" and moved on to parking regulations. As if houses hum on a schedule that someone maintains. Which, apparently, they do.
