Some cars do actually make an electronic sound to warn pedestrians of their presence. Mostly European cars, and the little hairdresser's Jeep thing I forget the name
You’re probably joking, but in case you’re not: Electric cars must make an artificial sound on low speeds in Europe to alert people. The motor is too quiet on its own.
He may not, maybe he's talking about the sound when the car isn't fast enough to alert people on the street, just to let know that something is coming. It shut at a certain speed I think
TIE fighters fly around in space, space has no air, sound are vibrations of air, no air, no sound.
So if you can make your car completely quiet, then it sound like a TIE fighter.
But since that is impossible since you want to br driving around, you should duct tape some speakers to the roof and have a synth generate a continous TIE fighter tone, which would create the proper effect
My head cannon is that TIE fighters don't make sound exactly as they zip around, but they do something to the electromagnetic fields or some other techno babble thing that causes other things, like droids, space ships, rocks, or skulls to scream with a Doppler effect like that as they zip by.
Look, in whatever far away galaxy the Star Wars movies are set in, sound travels through space. Pretty self evident since every spacecraft and space weapon in those movies is loud af.
I think the biggest obstacle would be from your perspective it would just be a steady annoying sound. TIEs only have their characteristic howl when doing a flyby. But if you're aware of that and you one want it for how it sounds as you drive by, I'd think just playing the tone through the speakers would do.
There's an audio illusion that's somewhat analogous to the barber pole illusion --- instead of a pattern which appears to always go up or down, you can have a sound which seems to always go up or down in pitch: https://en.m.wikipedia.org/wiki/Shepard_tone
It's pretty much certain some EVs are easier than others to jailbreak. Probably don't go with a Tesla. My impression is that established manufacturers tend more to build cars that are just cars, so maybe a Nissan Leaf or something.
I'm almost certain someone could build one of these that recreates the tie fighter sound. We need one of those YouTube makers with access to a metal 3d printer to design and build one.
Can't 3d print exhaust components. However, I was wondering what various whistle tips inline would sound like. If each has a different size hole, perhaps they would have slightly different frequencies? The combination might be tie fighter'ish driving by.
Bolt one end of some sheet metal to your bumper, leaving the other end to scrape along the ground. Should generate the required NYAAAUUUGGHHH sound wherever you go.
I can’t speak to specifics but I can give you some ideas.
So the obd port might have some basic info such as acceleration and turns since and/or at least torque/thrust readings that you can poll since insurance companies and others have devices that use them to track your driving (often paired with GPS which you don’t need)
So some arduino project that lets you plug in and poll that data and to establish a trigger for some audio could be fun.
This might be easier since a pi would be better suited to playback of audio and might be easier to get everything connected and to tinker with the Python to respond to certain readings
I saw such a device on Instagram. I think it was a Bluetooth connection from the computer diagnostic port to the phone.
The app takes this data and makes the right noise based on engine revs. The app was full of different engine sounds both real and fictional along with silly noises such as farting.
It'd be all through intake, not exhaust. That's where you get all the sucky whoosh noises sound from. Anything from the exhaust will be too explosive. Effectively, harnessing the sound of air being dragged into the engine for combustion, not being banged out.
The original sound was inspired by the sirens attached to Stukas in WW2, the siren wailing as the plane dove and air rushed through. These were added simply to terrify people.
However, there is rotaries. Adding rotary blocks to a rotary engine will make a much smoother scream sound, like the V10s and V12s of earlier Formula 1 cars. Though, it will be lacking that open air sound. Maybe with the right exhaust and intake, a tone could be achieved.
If you went EV, electric motors are high-pitched unless very large. You could combine this sound with air vents—catching air like the Stukas' dive bomb air sirens—to get something similar, however, the air vents will be dependent on making noise with constant speed, disassociated with the engine. The TIE fighter also has no electric noise, it's all terrifying roar...well, whatever the inhaling version of a roar is.
