Flight simulation is a realm where immersion is paramount. The ability to transport oneself to a different place relies heavily on the integration of various sensory inputs (what you can see, hear, and feel). From the intricacies of weather patterns and picturesque scenery to the authenticity of runways and flight deck displays, each element contributes to the overall immersive experience.

While visual components play a significant role in creating a sense of being elsewhere, the importance of sound should not be underestimated. The subtle hum of engines, the precise communication between cockpit crew, and the realistic audio feedback from the aircraft itself all work together to enhance the simulation experience.

Moreover, the utilization of original equipment manufacturer (OEM) components further heightens immersion by ensuring that every switch, button, and dial mirrors its real-world counterpart. This attention to detail not only fosters a more authentic simulation but also bolsters the feeling of truly being in a different place and time.

Computers

The simulator is using three computers (server, client 1 and client 2) and each computer has one sound card with client 1 having two sound cards.  This enables sound to be spread out over four sound cards to four locations. Sound is sent to speakers in the following locations:

  • Behind the Main Instrument Panel (MIP);

  • Behind the main overhead;

  • Beneath the floor structure; and,

  • To a surround sound system (2-4 speakers).

With the exception of the surround sound system that uses typical music quality stereo speakers, all the other speakers are small stereo speakers that have been mounted in strategic locations.  I have not used computer speakers as these produce a tinny low quality sound.

The speakers have not been connected directly to the computer; rather, I have used a number of inexpensive mains power stereo digital amplifiers that enable the sound volume, treble and bass to be easily controlled. The amplifiers also have the capacity to connect with one or two speakers. 

With the exception of sounds from MSFS-2020 or Prepar3d, the sounds are controlled by a number of instances of ProSim737 audio and two instances of SimSounds 4.

Sounds and Sound Programs

I am using sounds from the following sources:

  • SimSounds 4;

  • PM Sounds;

  • PMDG 737;

  • Immersive 737 CFM sound pack;

  • Turbine Sound Studios 737-800/900 CFM56-7B27 sound pack;

  • User specific sounds; and,

  • ProSim737 Audio 1 & 2.

Aviation Headset

An aviation headset is used to communicate when using VATSIM.  This is connected to the server computer via a Flight Sound X adapter.  The sound X adapter enables an easy connection of an aviation headset to a computer sound card.  To enable the headset to function correctly for Air Traffic Control (ATC) and to not have the engine sounds playing through the headset, MSFS-2020 and Prepar3D has been configured in the sound menu to split ATC and engine sounds accordingly.

I am not using an intercom system.

Butt Kicker and Vibration

I am not using butt kicker or any vibration tools. At some stage a butt kicker may be used in the simulator.
