I have seen a lot of people asking about soundproofing there dart board, so I thought I would do a little guide.
If you have neighbors who don't like the thud,thud,thud of your darts at one in the morning this simple set up should do the trick and all it costs is 2 quid.Things you'll need
PVC backed coir mat (coconut hair) 2 pound at Tesco
4 wedges or some beermats
Sharp scissors The Mat
Cut your mat to size, you may have to cut it in two parts like I have done.
Mount the cabinet to the wall and place the mat inside and attach bracket (use longer screws than the ones you get with the board if possible)
Then add the wedges or beermats for a nice tight fit and your all set for a nice quiet game
