A bridge rectifier in and of itself will not reduce the buzzing in a solenoid. That is, the voltage still rises and falls 120 times per second except the pulses are all in the same direction (positive or negative) rather than alternating positive and negative. You need to smooth the pulsating DC with a capacitor...or use a DC power source such as a DC-output wall-wart.
