The sound reduces slightly when placed into reverse, seemingly because the idle drops a little when placed into reverse. Park, drive, neutral, and the low gears all have the same sound when not moving, basically the same whine/whirling sound.
But the pitch of the whine does go up when idle goes up (accelerating), and then tones back down after letting up on the accelerator.
