Traffic related vibration and noise
« on: August 22, 2013, 07:31:54 PM »
Our 3 level townhouse (which we bought a few months ago) is on a busy street. Since we bought it (a few months ago) we have noticed considerable vibration of the structure when trucks pass by on the street. This only occurs when trucks go over bumps at a few specific spots, not otherwise. The vibration is significant enough that our bed (on the top floor) shakes and we sometimes wake up because of this. We have complained to the city about fixing the bumps in the road and hopeful that they will do so, but I am wondering if there another solution. From what I have read on the forum it seems that we need to decouple different parts of the structure for the best solution. But it also seems that putting vibration pads under the bed (in addition, perhaps, to putting MLV) may mitigate the problem. Could someone advise whether this second route is at all worth considering. If not, could you suggest alternatives.

A second question concerns reducing sound transmission within the house. Is there a solution we can use to isolate the bedrooms (2 regular sized windows) from both the external traffic noise and from noise within other parts of the house. Regarding windows, I have read about soundproof interior windows and also read about Jeld Wen dual pane windows with panes of unequal thickness. Does anyone have experience with either or suggestions for better solutions ? Regarding putting something in the walls for better sound isolation, what are the best options?

Our budget is modest - around 1-2 K for the windows and at most 10 K for the full set of problems. Thank you,

Get them to fix the bumps in the road.  ;D

Here's why; To eliminate the rumble and thump that is powerful enough to wake you from sleep would take as much as you have paid for the house.. well, pretty close. ~facepalm~ Because you would basically need to float the entire structure on springs.

However, there is a temporary solution: set your bed on spring isolators. I believe that the Super Soundproffing store has something that would work for you. - Only be sure to match the spring to the weight of the loaded bed. - You'll need 4. ;) Note: 1" deflection springs should do nicely as they will isolate down to 4.5 Hz.

Low frequency rumble and shock waves are extremely hard to stop or eliminate since they contain a very large amount of energy (power).

Addressing your second question; The best you can do would be good room seal (air-tight) and window replacement with certified STL windows. (STL = Sound Transmission Loss). If you can afford it, add another layer of drywall in the rooms affected. Don't forget the ceilings.
Window glass should be thick (1/4" or better) and double glazed with excellent air-tight/water-tight seals.

Thanks a lot, John. We will give those isolation springs a shot, while we wait for the city to fix the road.
