Isolation Sand Boxes


I built some MDF sand boxes and filled them with 15 lbs of sand. Why do they make my CD player sound quieter?

Er uhm, I'm not certain. Do you think that it may have something to do with the "tiny" little shovel and pail?
it sounds quieter because you're so chuffed with yourself for building them, that the sound just had to be better!
on a more serious note, maybe your cd player sounds quieter because you blew out your hearing using the power saw cutting all that mdf.
how come the big ticket audio reviewers never mention these possibilities?!
