Our two-floor wooden house was built three years ago according to our own specs by a local company. The house is “class 3-certified”. (I don’t know exactly the naming, but it means that it should, at least in theory, stand a 7-magnitude quake.) However, as the title says, while I’m working at my PC on the second floor the monitor vibrates a little while the washing machine is spinning at high speed on the first floor.
It’s true that this PC monitor, being rather large and attached to a relatively slim stand, oscillates a bit at the slightest touch by hand, but I wonder why a washing machine, which as such is not connected to a building wall except for the water faucet, can transmit vibrations so far away.
Any one who owns or has lived in a modern wooden house has experienced something like this?
