An MP Global Products customer (a homeowner) used the golf ball test to evaluate the reduction of sound transmission capability of two different acoustic underlayments - one of which was QuietWalk - under a new floating wood floor to be installed over a wood subfloor. It tested the sounds of a golf ball dropped on the floor (about 12 inches is a usual starting height for the test) and measured both the resulting tone from the bounced ball and the height of the bounce of the ball visually. This is a simple test that any homeowner or installer can conduct, even in the a store. A lower bounce (i.e. rebound) indicates a better ability of the underlayment to absorb energy.

In the homeowner's test, QuietWalk had a lower tone, which sounded better than the higher tone of the competition to the ears of the tester. And QuietWalk also "won" the bounce test - rebounding lower than the competition. 

Add to that all the attributes that help ensure optimized performance of the entire floor assembly and QuietWalk earns aces all around.

QuietWalk is a unique, earth-friendly, acoustic and insulating laminate and floating wood floor underlayment that smoothes out little subfloor imperfections while quieting impact sound and floor to ceiling noise. QuietWalk dampens ambient sound in the room it’s installed in and helps minimize impact and airborne sound from traveling into the room below. QuietWalk’s patented manufacturing process and recycled fiber composition (minimum 94% pre-consumer recycled fibers) create a unique moisture management system to protect the overlying flooring from harmful water vapor while retaining its exceptional compression resistance over the lifetime of the installation.
