It's not even really the spool sound - you'll hear that more through the intake. The wastegate dump is extra exhaust that is dumped once you hit your boost target. So, if you're set to run 12psi, everything above that from the exhaust is dumped out (either to atmosphere or back into your exhaust) to not overspin the turbo.
It's just muffled or unmuffled exhaust noise - more like a blaaat noise, not really a nice sound. Just loud.
And yes, the "psshhh" sound is from the BOV.
