I've always wanted to ask an audiologist whether "active noise cancelling" type technologies actually pose an auditory risk. They kind of have to emit the same amplitude-at-the-ear of audio of what they're cancelling out, right? And sure, most of the time the waves cancel, but maybe the algorithm gets it wrong a couple milliseconds at a time and - while possibly not perceptible - are those high peaks of audio-cancelling-sound damaging?
