I think it would be pretty tough. Especially if you don't want to just sit in one place. The problems is spatial, there are many paths for the noises and positions for the listener.

I don't know about acura but I read an article about electronic mufflers years ago and as I recall the key was that the noise was predictable. With just a few variables like throttle position and RPM the appropriate cancellation signal was known. The other thing that made it possible was that they could apply the cancellation at the single point where the noise was being generated, the exhaust pipe outlet.

In your case the noise is unpredictable and can come from any position and the listener can wander. The general solution is a noise wall which can be made large enough in some instances to reduce the position dependencies or noise canceling headphones or earplugs.

I grew up in a quiet world but I sure don't live in one now so I wish there was an easy answer. Since noise walls can be made of glass you might consider something like a few courses of building block with glass panels on top relatively near where you want to sit.

Good luck, Rick
