Rumbling in Toronto, Ontario

Annoying AF. A low rumble like a truck engine revving. I feel the vibration in my whole body and even my eyeballs if I focus on it. Louder at night, but I hear it during most of the day if I’m inside and it’s quiet. Started hearing it in August, 2019. You need a better sample of the sound. The sample you have is way too high-pitched. The sound i hear is a very low vibrating frequency. The closest thing it sounds like is an idling truck engine or construction machinery.

What they reported

First noticed: 2018

Pitch: Your generator does not sound a thing like it. Like not even close.

Loudest: During the night

Where: Indoors

Symptoms: Headache, Nausea, Sense of vibration, Anxiety, I feel it in my eyeballs. It’s kind of scary. I broke a blood vessel sleeping since I started hearing it. And I’m pretty sure that’s why.

Changes with weather: I started hearing it in the summer and now it’s almost winter, so no.

What stood out: rumbling

The sound seems to come from the sky, an intense vibration. Similar to the frequencies emitted by a diesel engine of a car with a slight acceleration or a larger engine at slow speed. Someti
