Not that I would commit such a heinous offense, -but- this idea came to me the other day.

What if there were somehow premium protected speakers strategically installed into the wheel wells, engine bay, exhaust area, which were hidden from view. Along with some high powered subs could rumble the car realistically, and a recording of say a v8 vette or something nice sounding was played out of those. I don't know why but I just find that so .. oddly interesting. Imagine seeing a civic sitting at a light roaring with some enzo sounds. lol - omg. The thing is, I really think the effect could be believable if its tuned correctly. How horrible am I for thinking about this -

. Geeze, imagine anybody being able to push a button and have the perfect BOV sound shoot out.

I know if some company (or a DIY techie) really wanted to, they could somehow attach something to the gas pedal which detected precisely how much gas/pressure is being applied and sends the appropriate sound, similar to pushing the gas in Forza. Imagine being able to choose what you want your car to sound like everytime you get in it.

What do you guys think about it lol? Insane.
 
Yeah, I want my Prius to sound like a twin turbo Grand National.
 
Are you serious? :lol:

Of course it could be done, the question is though, WHY?! If I saw/heard it, I think i'd bust a nut laughing.
 
I had this happen to me once on accident. I accidentally pressed "band" on my radio, and a low-frequency AM station came on - like, 610 or something. For some reason, the engine noises of the vehicle were then played over the radio. When I put on my turn signals and honked my horn, that too was heard. There was interference as well, but you could clearly hear the car accelerate and decelerate. I eventually grew tired of it and turned my CD player back on, but I was able to replicate it several times. I hadn't tried it in months when I finally sold my car in September.
 
Of course, it could work the other way round - play the inverse sound of the car and have a completely silent vehicle...
 
Our older RV suffers from this. Turn the radio on to AM and then turn the CB on and it will start blasting out the motor revving at very high frequencies. Sounds like a Formula One car.

Yeah - it's very F1-sounding. Operating at high RPMs it's actually kind of funny.
 
Wow that's weird. The only sound we ever got through the radio was the spark plugs :grumpy:

Thinking about it, it couldn't have been, but it was a popping noise that was more rapid the harder the revs.
 
Imagineif you made it sound like a race car (w/appropriate volume). Think you could get cops pulling you over to check if the exhaust is legal?
 
It's a noise violation one way, faulty equipment the other.

I wouldn't want to get pulled over for either reason.

If you have to do this, you need a new engine, not a new sound system. :p

Now this is a nice idea. Sure, you'd never know when your engine is stalling, but Rolls-Royce and Bentley could save hundreds of kilos on soundproofing....

You're not really hearing the engine sounds. Since there's nothing broadcasting under the hood, there's nothing to be picked up. What you're hearing is resultant RF noise that happens to be picked up on 610kHz (the exact frequency may differ from car to car). There's all sorts of electro-magnetic noise under the hood, between the pistons sliding through oil, spark plug timing, electric fuel pumps, other sensors.... It's sometimes audible on other AM stations that don't have anything broadcasting in that range. You should also be able to hear it on multiples of that frequency (in your case, 1220kHz). Since it came and went, and you heard the horn, it was probably due to a loose or fraying AM antenna.
 
I think i would make my mustang sound more like a nice quiet Jetta or somthing nice and tame like that..... i'm getting mighty sick of hearing the sound of a 4.6 through long tube headers and an x pipe w/no catylitic converters....:lol:

Honda is using this technology on the Accord Hybrid (they call it Active Noise Control, aka ANC) to both quiet the engine and disguise when it is running in 3 cylinder mode by making it sound like a V6.

:ouch:

That (overclocked's idea) would be neat for a while.
 
Chavs with Novas and Saxos would have a field day.

Oh course, in theory, it could play whatever sound possible. For example: their friends could swap the sound files and make it quack like a duck. That would be too precious...

I would have thought it'd be quite hard to get the sounds matching up - an enzo sounds nothing like a Peugeot, for example, so you'd get clashing sounds.
 
Nah, I don't think the Nova/Corsa/Saxo crews would take to this too much. They love being heard from miles away with their massive exhausts. It would take some serious wattage to boost the engine sounds over a few miles.

Ick. That is teh gaye. :yuck: *scratches Accord Hybrid from possible list of commuter cars...*

It's very simple. Replace sound waves with water waves. Picture continuous waves, one after the other, up & down, up & down. Now picture it being contained in a long trench, so you can see this up & down waveform (sinusoidal wave) from the side. Then bring an identical trench next to it, only where the first trench's waves are up, this second trench is down, and vice-versa.

Now that you've got all this stuff sitting on your table, picture the two side by side and merge them together, like ghosts. The energy from wave 1's upward part will match with the energy from wave 2's downward part, cancelling out in the middle. This will happen for the entire waveform, resulting in very calm water.

Sound waves, particularly that of something complex like an engine bay, are much more complex if you were to see them represented graphically, but they can be recorded, inverted, and played back alongside the original sounds. The resulting noise level in the car should -- in theory -- drop dramatically.
