When the central heating blower for the Opel 3 firepalce comes on, I hear a loud humming noise from the basement. It doesn't sound bad when I go and stare at the unit, I think it's a combination of motor noise and vibration transmitted directly into the floor above.
Any way to isolate the fan from the wood framing above? Any other way to suppress the noise? The whistling of the air going around the fireplace is tolerable, but that constant drone from downstairs sounds awful.
