I learned this when I was in my teens driving a twin engine boat. The throttles are independent so you listed for the resonance waves to get the engines in sync.

All I heard was the engine room of the Enterprise.

You get the same thing on twin-engine boats or aeroplanes when the revs are slightly different. One revolution per second difference gives you one beat per second. Same thing happens when you have 3 or more engines, though it's more complex to calculate the beat pattern.

Would sometimes hear this happen on the highway with my exhaust drone and bass from music. Always wondered why

What is compound binary form or sonata form?

I would get super Mad but least some people get to have a Great Teachers, but lots of schools they just don't care! Life can be extra unfair and that's just how it is! As an adult it may be later but now you can find them by searching and making it happen!
