my response was to the 'it should be an easy fix' sentiment. trying to address feedback loop without negatively affecting cancellation performance is extremely challenging, because for a mic/algorithm there's generally no way to determine if the error microphone is picking up a loud event in the environment or if the cancellation soundwave is incorrectly phased and instead of canceling its just adding more noise.
