I call bs on that one....
If you have a vibration issue, the best thing to do is absorb it and make sure anything that is vibrating is secure... I had a tenant that was constantly complaining about her upstaris neighbor and his tv, he only had a little sony subwoofer, but I wanted to make everyone happy so, I lined upa meeting between the 3 of us. I had him put his tv louder than he normally plays it and we went down stairs, the issue was she had some things vibrating in her home on the walls, some double sided tape on her hanging pictures, a piece of soft foam under his subwoofer {we dissected a couch cushion for it}, and a verbal agreement not to play the subwoofer before 9am and after 9pm {I bought him a timer for the subwoofer outlet, so it would automatically shut off after 9pm}. and everyone was happy..
It just takes a little consideration and attention to detail to cut down on the noise, but I have to say shiny foil to reflect sound waves and a towel to absorb sounds like BS when used in such small scale..
