“Some time ago they had the opportunity to record Tesla motor noises when a prototype was being run on a dyno at Tesla. But the teams were excited about the prospect of recording other sounds, particularly tire skid and squeal noises, without the interference of loud engine and exhaust noise. Of course I said “yes.”,” Burt writes on the Tesla Motors blog.
The teams chose a local motorsports park, formerly used as a small airport, where they had three large boom mics “suction-cupped” to the side and rear of the car, a mic in the trunk, two at the front over the swaybars and near the front tires, plus one in the cabin interior. The owner drove the car himself.
“We did a lot of baseline sound recording of 10 second segments at 10 mph intervals up to 50 mph after which wind noise became an issue. The pavement at the facility included smooth, broken/dirty and very smooth and grippy pavement due to application of VHT compound for drag racing,” Burt explains.
“We were able to get clear recordings of the sound the tires make over these different pavement types at the various speeds. Next was hard braking over these different surfaces from 100 mph. Then the real fun started — hard sweeper turns (generating good tire chirps at the edge of adhesion) then more aggressive skids and slides on the various pavement conditions at the track,” he said.
Since the project seemed to have completed successfully, gamers should pretty soon hear the Tesla 'roar' while playing Forza or Project Gotham Racing.
