sound deadening

This may not be the correct forum but I'm searching for a fairly economical way to deaden, or at least reduce, our household noise levels. Four by eight sheets would be preferable but I'm open to almost anything within reason. Some of the stuff I've looked at online is unbelievably pricey but perhaps there's a good deal out there I've missed.

A little more info may be helpful, dirt. One wall, all outside walls, isolate the sounds coming from teen son's bedroom, upstairs/downstairs? Lot of factors to consider.


Measure it with a micrometer; cut it with an ax.

Interior type sounds - a wall between two bedrooms and a wall between a bedroom and bathroom. Muting conversations and the occasional flush.

Okay, the major problem with trying to dampen the sound is that sound travels through solid objects, so regardless of how many layers of material you put, the sound waves can still be transmitted through the wall(s). Ideally you would have a gap between the walls that would prevent direct contact between the surfaces. This can be done with offset studs, but requires major work on the wall. Insulation inside the wall between studs can help some, but again that is going to require major work, i.e. pulling down one side of the wall to install the insulation. Other way to kill the sound is by isolating the drywall using what is called Z-channel. What this does is offset the drywall away from the actual sutds and serves to lessen the amount of sound transmitted through the studs. As with the other solutions, this will require some major work to the walls. there are some drywall materials that purport to lessesn sound transmission, but I don't know if the amount of deadening would justify the cost and, again, it will require major work. Here's some info on the drywall products:
