Discussion on Active Noise Cancelling Performance

I was wondering recently, is there an industry standard way of measuring the performance of ANC on headphones.

I’ve been watching/reading reviews on various products in this category and people describe the ANC on some headphones being “better” or “worse” than others, with some comparing the same product on different firmware revisions.

Personally, I’ve only used a handfull of ANC headphones and it seems to be a very binary feature for me, meaning either you have it or you don’t, but like with all things, it seems there’s more to it than that.

If anyone has any good resources on this technology, whether it be theory or implementation, I’d love to learn more about it.

The only place were noise canceling headsets are actively studied are in aviation. A search in this area will yield a lot of info.
