Documentation/Engine/Units/sound noise data

The sound_noise_data unit class is used to define speed-dependent sounds. This unit is typically used in an array, with min_speed and max_speed ranges overlapping between members to allow crossfading.

Uses

• accessory_sound_data (wheel_*, aero_noise, gear_noise)
