I bought one kiln dried 25KG sandbag. I had an idea to put many bags under my bed. I bought one bag to begin with, because I like to think about thi ngs, just in case I make a mistake.
I did a test. I dropped a heavy object on the floor, away from the sand ba g, and felt a "tremour sensation" in my feet and legs. I then dropped the same object right next to the bag, and felt nothing.
Based on this positive result, I had the following idea. Could I put many sandbags along the base area of the "noisy wall"? Would this help to someh ow "catch" the vibration tremours as they leave my neighbour's house, befor e they reach my bed/bedroom?
Most of the "noisy wall" happens to be my stairwell. Consequently, I was t hinking of placing one sandbag on each stair. I don't mind about the appea rance or inconvenience, as I'm sure I'll be able to walk up and down the st airs with these bags on them.
However, is weight a concern? Each bag weighs 25KG. Generally speaking, h ow many KGs can you have in an upstairs room, before the ceiling starts to sag?!
Thanks a lot for any further suggestions.
