The wastegate is more a valve that vents excess exhaust gas around the turbo, not all the gas. If you saw how big a standard wastegate is, you'd understand a bit better.
So the wastegate regulates the speed the turbo spins at which determins the boost pressure (pressure of air being pumped into the engine by the turbo).
A BOV only opens (goes 'psssscchhhhhtt') when the throttle is suddenly closed and the pressurised air going into the engine all of a sudden has no where to go, but backward through the turbo and out the air filter, which causes the turbo to stress a bit, and also means the turbo has to spin all the way up to its max speed (as regulated by the wastegate) which means a bit of lag.
So the BOV allows the turbo to keep spinning with the throttle closed, as it vents the boost pressure outside, or in the case of standard cars with BOV, back into the intake and into the turbo (so that's why you can't hear them).
