A low hum in Canada, Holland Landing
Low frequency hum and vibration Hum started after a peaker electricity power plant was built and is served by high pressure natural gas lines !!! Before my investiagtion, i assumed it was a commuter train idling at nearby train station. Eleiminated it as a source. Investigated hum at 2 AM in car with closed wiindows and driving in various areas..found it extreamly loud in some areas -even with windows down. Need building materials of home to really amplify and sense vibration. Can actually hear vibration through pillow and bed ! Have also used audio app and ipad to graph low frequency him...very obvious however may be reading electronic or app “noise” ...have to confirm a baseline without built in mic connected to test...but clearly see peak at 5-50 Hz.
What they reported
First noticed: 2015
Pitch: 49 Hz

Symptoms: Ear discomfort (pain, fullness, throbbing), Insomnia, Nausea, Sense of vibration, Total frustration and anger.
Changes with weather: Less noticeable in hot wx..maybe due to windows open.(hum very bad sue to building resonating) Less noticeable in very mid winter with deep snow cover and frozen ground.

The sound is best descibed as deep vibration or low hum that sounds like it is from an engine or truck, but the sound seems to be travelling through a medium as a vibration. Sometimes it fl…

It is a low-frequency humming noise that has no explanation or source. I hear it mostly at night and inside my home. The noise is similar to a train or a diesel truck engine idling and the…
