Title: Dampening Sound of Basketball Backboard
Post by: BB Dad on January 20, 2014, 10:52:39 PM
I just finished putting together my son's new basketball hoop.  it's one of the portable ones with the big base that you fill with sand or water.  the backboard is clear acrylic, and the problem is that whenever he shoots a long shot (which he does often, he's a fan of the three pointer), it makes a really loud booming noise.  I want to be a good neighbor, so I am looking for some ideas on how to dampen out the sound.

Thanks in advance for any advice.

Well I am not sure how well this will work considering the impact noise created by the ball hitting the back board will still remain the same after any soundproofing attempt is made.
Like bouncing the ball against a concrete wall...there is still a good value of noise created.

If we dampen the back of the plexi glass you might see a very slight reduction and if we attempt to dampen or absorb the impact on the face of the back board it might change the way the ball reflects into the basket.

I still to this day find it amazing that something seemingly simple is actually pretty difficult.

This will be trial and error for sure...

First attempt..glue a layer of mass loaded vinyl to the back of the back board with construction adhesive. (liquid main or Premium PL construction adhesive) full coverage not spot gluing.

If that doesn't work well enough you can do the same to the front of the back board.

let me know the results...this will be our first attempt at such a project.
