I like to listen to the noise or tune of the saw, I was taught to always listen to the piece of machinery your using. By doing this you always know if there is something happening to the saw or if it's working properly. And as far as I'm concerned, it's just another distraction that's not needed around running machinery. But this only my personel opinion, and I think that whatever makes a person more comfortable around the shop, is what they should do in the long run. Because afterall it should be as enjoyable and stress releving as possible,and I do like to listen to the machinery operate, really. Weird huh?
