Sound simulation system

Claim 1

A DEVICE FOR REALISTICALLY SIMULATING THE SOUND IN A JET AIRCRAFT COMPRISING: ELECTRONIC SOUND GENERATING MEANS INCLUDING MEANS FOR GENERATING STARTER NOISE, MEANS FOR GENERATING TURBINE WHINE NOISE, MEANS FOR GENERATING AFTER-BURNER NOISE, MEANS FOR GENERATING VENTILATION NOISE MEANS FOR FLIGHT NOISE, MEANS FOR GENERATING TIRE SCREECH NOISE; RELAY MEANS OPERATIVELY CONNECTED TO SAID NOISE MEANS FOR ON AND OFF CONTROL THEREOF; FIRST AMPLIFIER MEANS; MEANS FOR MIXING SAID DIFFERENT NOISE MEANS AND APPLYING THE OUTPUT OF SAID MIXER MEANS TO THE INPUT OF SAID FIRST AMPLIFIER MEANS; CONTROL MEANS COUPLED TO SAID NOISE MEANS FOR CONTROLLING THE APPLICATION OF SAID INDIVIDUAL NOISE MEANS TO SAID MIXING MEANS; AND MEANS FOR SIMULTANEOUSLY TRANSMITTING CRASH SOUNDS TO SAID FIRST AMPLIFIER MEANS AND FOR SIMULTANEOUSLY DISCONNECTING SAID NOISE MEANS FROM SAID FIRST AMPLIFIER MEANS UPON A SIMULATED CRASH OCCURENCE; SAID MEANS FOR GENERATING TURBINE WHINE NOISE COMPRISING, MEANS FOR GENERATING RANDOM NOISE WHICH INCLUDES, A SOURCE OF RANDOM NOISE, POTENTIOMETER MEANS COUPLED TO SAID SOURCE OF RANDOM NOISE FOR CONTROLLING THE FREQUENCY THEREOF, MOTOR MEANS OPERATIVELY CONNECTED TO SAID POTENTIOMETER MEANS FOR EFFECTIVELY VARYING THE FREQUENCY OF SAID SOURCE OF RANDOM NOISE THEREBY SIMULATING THE NOISE RESULTING FROM THE R.P.M. VATIATION IN THE TURBINE, SECOND AMPLIFIER MEANS FOR AMPLIFYING SAID RANDOM NOISE, AND FILTER MEANS COUPLED TO THE OUTPUT OF SAID SECOND AMPLIFIER MEANS FOR PASSING ONLY THE DESIRED SOUNDS.
