GB Sound module USM-RC

22 BEIER-Electronic 28.07.2008

Engine sound (Slot #1 - #9)

The engine sound consists of several single noises. Normally there is a turn on noise,

idling noise, driving noise and turn off noise. This sound module offers also the

possibility to imitate a driving noise under partial load, a reverse driving noise, a

brake noise, a starting noise and a stopping noise. All engine sounds (therefore also

the reverse driving and brake noise) play only when the engine sound is switched on.

Turn on noise (#1)

The turn on noise is played when the engine sound is switched on. After the turn on

noise was played, the sound changes into the idling noise.

If the engine sound is switched on and the vehicle is already in motion, the turn on

noise will skip and the module directly plays the driving noise.

Idling noise (#2)

The idling noise is always played when the vehicle is in idle. The sound is played in

an endless loop. It suffices therefore, when in this sound slot a relatively short sound

(approx. 1-2s) is stored.

Starting noise (#3)

The starting noise is played uniquely when the vehicle sets off (idle Æ drive).

Driving noise (#4)

The driving noise is always played when the vehicle drives. The driving noise is

always played like the idling noise in an endless loop. The playing speed is

dependent on the speed of the vehicle. The sound module recognizes how fast the

vehicle moves, and plays the driving noise also in the corresponding speed. In this

sound slot the driving noise is stored in the slowest driving speed. The sound

module produces all faster driving steps (up to 75) itself.

Driving noise in partial load (#5)

When the driving speed of a real vehicle is reduced, the sound character of the

driving noise changes (engine produces less power). This effect is also possible with

this sound module. In slot #5 “another" driving noise can be stored, that always is

played when the driving speed is reduced. The driving-noise in partial load is played

speed-dependently, too.

Stopping noise (#6)

The stopping noise is played uniquely when the vehicle stops (drive Æ idle).

Turn off noise (#7)

The turn off noise is played when the engine sound is switched off.

Reverse driving noise (#8)

The reverse driving noise is played when the vehicle drives backwards. This could be

e.g. the beeping of a reverse driving warn sound of a truck.
