as expected, you couldnt do it yourself becaues you dont actually understand any of this.. and so you outsourced it to AI to reproduce what is says on the package for marketing.
in reality, what noise cancelling headphones do, is produce a phase shifted signal so that the waves cancel. if you just produce the frequency signal, it wont work, in fact it will probably amplify. the key to the solution is to phase shift the signal by pi.
its not frequency, its phase. your entire world view is a lie.
sorry.
