Now that the house is finally finished, I have started to put together my basement shop. This is a first for me as all prior work was done outside or in a garage that shared space with everything else we owned. Part of my effort is to reduce noise in the shop space for myself because I spent a summer in while in college counting the blows underneath a pile driver (which about like being beside a cannon when it goes off). My hearing took a beating out of that summer. Even though I always wear hearing protection (if I am going to spend much time cutting using both ear plugs and muffs), reducing noise is a big deal. Here are measurements from my equipment and results of some attempts to reduce noise levels. All measurements were made at my ear level when I am operating a piece of equipment with the exception of the dust collector where I measured at the table saw location.
Table Saw ( Hammer K-3) Concrete floor- sheetrock and block walls
On wheels & standard front feet - 88 dba
Vibration dampers under wheels and feet - 84.7 dba
10 inch blade 84.7 dba
12 inch Silent Power blade 84.7 dba
added a horse stall mat under the saw 84.7 dba I was surprised at this making no difference
lining the saw cabinet with noise dampening material (like used in cars) NO DIFFERENCE
I made no attempt to surround the saw exterior with a noise blanket because there are just too many places for noise to leak out that really do require access.
Jointer Planer (Hammer 16 inch) 71.8 dba running no wood, 78 with dust collection & jointing in progress
Band saw
Running 83 dba, cutting 85 dba
Installed stall mat under the saw 81 dba
Installed noise dampening material on saw door 80 dba
Dust Collector - Onedia V system 3 hp - 74 dba (nothing else running)
Miter Saw
Away from the wall 90 dba
Next to the wall 92 dba
Obviously I need to look at materials on the wall s that absorb sound, but that don't collect dust!
Hope this helps someone else.
