Soundproofing a hand striking bag

[heyguy]

I live in a 2nd floor apt of an old two three story house. The striking bag right now is set up on two concrete hollow blocks. Basically its like a small earthquake when I hit it, and sometimes the owner downstairs gets curious wtf I'm doing.

Any ideas on how to prevent the whole house from shaking? Maybe some kind of vibration chamber wood stage construction; I know if there will still be a loud smack unless I soundproof the room, but at least I'd like to prevent the floor and walls from shaking.

I had a puzzle mat underneath, that didn't work. I'm thinking of putting a tire on the floor, then wood, then the concrete block somehow making the height. Will let you know monday if it works.

WTF is a striking bag?

I think he means a punching bag, probably a small one. Why not just hang it up?

Warning, massive blowhard answer:

Vibrations , fire and water are the hardest things to control in a building. Any material that carries the vibration will send it down stairs. Tire, wood, concrete etc are the same sort of materials the building is made out of and won't baffle the sound.

A big tub of sand would work, lay your bag ontop of that. Lots of carpeting underlayment would also work, but you'd need about a foot thick if you're hitting your bag.

btw, are you going Travis Bickle up there in your ol'apartment?
