I have been using some earbuds for music and then some big earmuff

reducing headphones for hearing protection. I have a feeling they only
stop normal noise and would not provide the protection I am looking
for but thought I'd ask on the off chance that I could exchange 2
things sitting on my head for just one.
thanks for any input you might have

Sound reaches and damages the structure of the ear in two ways -
through the ear, and transmitted up from the body. *The way you
control noise is through distance, density, and dampening. *I just
wrote those two lines of BS just to say I recomend thesehttp://www.stratfords.com/earplugs/earplugs_bilsom_twosizedown.html.
They are not muffs, but plugs. *They are the most comfortable plugs
you'll ever wear. *They are basicly a thin plastic "plug" filled with
down. *

Noise attenuation up to 39 dB. *We did a research study on
similar models and they are very effective for industrial noise.

The noise woodworking machinery generates is most energetic below that
8 KHz attenuation of -39dB.
Those plugs have a listed SNR of 27 dB. Period.

BUT!! Wearing plugs or muffs is absolutely essential in a woodworking
shop where powertools are used.
I just get miffed at the 'specs race'. Those -XdB claims are mostly
suspect and based on junk science.
