How much can be reverse engineered from sound ?

I wonder why many cars make almost no noise?

I agree. I hate noisy cars an motorbikes. They should be banned.

I can see the need for some noise and electric cars can be too quiet, as people don't hear them coming, but a lot of it is excessive.

A good V8 at 9000+ rpm sounds pretty cool IMHO.

While I am impressed from an engineering perspective that one can build a macroscopic machine which runs reliably at that high rpm (well, at least reliable for the duration of a race), I personally hate the sound.

If you want to enjoy that sound at home, I recommend buying a model aircraft engine. Better check with the neighbors first.  ;)

A Ferrari F1 V12 engine sounds nothing like a model aircraft engine.  I've heard people suffering from a broken exhaust on their car with a wheezy four pot engine and say "it sounded like a Ferrari".  Is a significant proportion of the population unable to distinguish different sounds?

What a lovely noise, I could listen to that all day  8) 8)

--- Quote ---In 1994, Harley-Davidson filed a sound trademark application for its distinctive V-twin engine sound. It realized that if it could capture its own sound, it could distinguish the brand at every point of customer interaction. Just like a visual logo, the most essential qualities of a sound logo are uniqueness, memorability, and relevancy to the brand promise.

I also thought the race engine in the first video sounded a lot like a model
Airplane engine, high pitched whine, very short stroke, very high RPM, it's not a sound I find pleasing at all but to each their own.
