Its ability to "ignore" music inside the car could/may be adapted to other distinctive noises as well - jackhammers may occupy a frequency that can be cancelled, while sirens may occupy another frequency that the system might be built to ignore. I've tried to find more info on the Honda/Acura active noise cancellation system as well, which has been around for some years, but with no success (though I believe it is a Bose product, and the Bose headphones "ignore" speech and sirens, so that's possibly/likely applicable in the Honda/Acura models).

I don't think it was Toyota, but I'll try to pay more attention the next time I see it. I do remember that the emphasis was on not hearing any "outside" noise. In one ad, they had a bazillion clocks (coo coo and otherwise) clanging and coo cooing away outside the car, but you don't hear anything inside the car. The car isn't moving ... so it's not a matter of canceling out engine noise. I'll just have to see if I can remember what car it is and if they have the ads online
Anyway .... I just came in from outside (took the trash out) and it was amazing out there. Totally clear directly overhead ... tons of stars ... but to the Northwest, a HUGE thunderstorm with a great light show. Then, to top it off, as I'm watching the lightning, a meteor streaks overhead and breaks up in the atmosphere. It was very bright and a distinct orange-yellow color. Really beautiful.
