Why does turbo engine produce less engine noise than naturally aspirated engine?

Sorry for the noob question. Tried search google and the answer said turbo engine are usually smaller engine. However, many of BMW cars are using 4.4L turbo engine but why is it still makes less noise than the M3 naturally aspirated 4.0 v8 engine ? Thanks !
