The buzzing noise could be the buzzer for a problems with the brake system. If the brakes are not working at all, check to make sure that there is fluid in the brake master cylinder. Low fluid can make the buzzer sound, and is an indication of more severe problems.
You are hearing the electric fuel pump in the tank, That is common on a chevy.
Most likely the noise is from the brake pads rubbing against the brake drums. This may be because the pads are worn out- makes sort of a scraping noise. This condition requires immediate attention. Some type of pads squeak when they are new and in damp weather - annoying but not a real problem. If you get a thumping, bumping noise, something is lose-- make sure your wheels are all bolted on securely. Check your shocks and see a mechanic.
it could be that your exhaust pipe is lose, i saw a Forester (a litttle newer than that) with the same problem.
it could be your tires on the pavement.
Probably scoured or warped rotors.
