1. The problem statement, all variables and given/known data How can one reduce the vibrations entering the house? And why do certain sounds vibrate more in certain place, but quiet fown if you move a bit further away. 2. Relevant equations 3. The attempt at a solution I was thinking it's something to do with the fact that sounds wave are mechanical waves, they need a medium to be propagated. I thought maybe a vacuum or something of the sort could help.
