Start up sounds

[Squatchpilot]

Just curious…the sounds are absolutely top notch amazing!! However, one thing I remember distinctly when I flew on one of the last Tristars in 99 was the deep hum on engine start. You guys have nailed it in exterior view but on the interior it’s virtually not there…can we add the deep hum of the 211 on the interior start up sounds? It’s almost a trademark of the Tristar on engine start!
