Andis & Wahl are excellent clippers...I have both & they're very quiet, but they were over $100/ea. I find human clippers to be noisier & it vibrates more.
What kind of blade are you using? It sounds like clipper burn. That's when the skin gets irritated from being cut too short & it can cause serious burns & red skin. They do have safe sprays to soothe the skin, made especially for dogs, like this:

Any blade under 7F (1/8" blade cut) will leave a very close shave & likely cause irritation, esp on a thinner haired silky dog. They can get sunburn too.
