Microsoft Flight Simulator X: Steam Edition - 737 Extreme Sound (2016)

The 737 Extreme Sound is an accurate sound pack for the Boeing 737 NG series. This sound pack simulates realistic internal and external spool, real world buzzsaw/engine grind sounds, accurate battery and cockpit ambience noises, and immersive ground rolling sounds. Also included is a custom sound gauge that can be added to any aircraft. The sound gauge adds GPWS altitude callouts, a 2D panel for controlling the air conditioning and crew notification sounds, and simulates the TOCWS.
