    OK Rod: Router sound levels.

    Bosch 1617evspk router mounted in table
    idling full RPM: 96 dBSPL
    Cutting 1/2" straight carbide spiral bit 1/4" deep dado in cedar: 100 dBSPL

    I decided to stay with the C-weighting - at 90 dB and above, the ear's relative sensitivity to low frequency rises so C-weighting is probably more appropriate for louder noise levels.

    If your only tool is a hammer, you tend to treat all problems as if they were nails.

          Great information

          Loring,

          Thanks for taking these measurements. I knew the tools were loud, good to know jus how loud. I'm glad I wear hearing protection (my dad made me do that from a young age). I know this is a bit off topic, but any idea how loud a gas powered lawn mower is? I think my dad and I must be about the only people I know of that wear hearing protection for that.

          As a side note, that Radio Shack SPL meter you use gets around. I happen to know that is what Dolby Laboratories engineers use to calibrate levels in theaters and mixing studios.

          -Jim

            Very interesting. I may add 1 thing: I have a Hitachi dual-base router instead of Bosch 1617. Hitachi router is advertised as "the quitest in its class" and technical specs for it are 85db, which is full 10db better than the 1617 as Loring measured. I can confirm from my experience that when I use Hitachi router in my basement shop my wife being one floor above does not hear it. She hears well other routers or BT3100 running. Not a scientific proof but does support the Hitachi claim. So obviously - not all routers were created equal (and probably not all saws, etc). If noise is important to you - go for Hitachi kit. I believe BT is considered a noisy saw, I wonder how it compares to Unisaw or Powermatic.
            Loring - can I ask you to buy yourself one of those and measure noise levels please?

              I am not buying any new tools to test noise on. However,
              if you wish to send me said tool to measure I shall be glad to do so.
              It might take me a while to return it or there's always a possibility it may get "lost" in the return shipment... :-)

              On a serious note, it's commonly accepted that universal motors are much louder than their induction counterparts. And I believe that's true from
              what I've observed.

                Delta 22-580 Planer: 89dB
                Hitachi C12FCH Miter Saw: 96dB

                Hitachi M12V Router: 92dB
                Delta GR450 Grinder: 70dB
                Jet 1014VS Lathe: 50dB
                Ryobi BS902 Bandsaw: 74dB

                  Regardless of the math I ALWAYS wear my ear muffs no matter what tool I am using; well except things like cordless drills, etc. Loud noise hearing loss is progressive. Except try telling kids with the bass loud enough to rattle windows! Me; rather safe than sorry.
