Punching Bag Noise

hi, I don't really plan on getting a punching bag right now but I was wondering how much sound they make. I'm planning on putting one in my room. is there a stand or a stand up punching bag that you guys would recommend? my room is a good 5-9 metres away from the 2 other rooms and the living room. if I have my door closed do you think my family would be annoyed by the constant noises. roughly how loud would u think it would be? and could the noise be dampened by having foam on the bottom of the stand or the bag? could I wrap soft foam around the bag? just wanted to know for the future.
thanks :)
