Bathroom ducted exhaust vibrating upstairs
I have a 1+1 house with the ground bathroom straight below one of the bedrooms. When someone turns on the exhaust fans below, the bedroom above starts vibrating enough to wake up whoever is sleeping there. I removed the vent checked, it is a ducted exhaust fan and I’m not sure if I can DIY something to fix this? The house itself is about 12 years old and exhaust fan does its job fine, just the vibrations being nuisance.
