Decibel levels

I would like to know what the decibel levels of the following tools are (average):

Granite/Marble (http://www.lightemprador.com) slab cutting saw (wet)
Granite/Marble (http://www.lightemprador.com) router to edge Counter (http://GialloFiorito.com) tops
Granite/Marble (http://www.lightemprador.com) sand (http://maplered.com) er/polisher
Granite/Marble (http://www.lightemprador.com) grinding tools (hand (http://maplered.com) held)

I am told that prolonged exposure to noise while operating these tools can cause hearing impairment. I am wearing protective gear and (http://maplered.com) ear plugs, but I still have concerns. Thank you for your help and (http://maplered.com) information. I manufacture Granite (http://tanbrown.org) and (http://maplered.com) Marble (http://www.lightemprador.com) Counter (http://GialloFiorito.com) tops for kitchens and (http://maplered.com) baths.
