I suspect this is fixable in firmware. What I heard on a long haul flight was the faint sound of the plane's engines traveling back and forth down a paper towel tube; a hollow, cavernous sound. It must be so tricky to nail these algorithms, but with the data of millions, it should be easier to triangulate and address.
- garyfirestorm 1y agoi disagree here - having a feedback loop that makes loud noise instead of cancelling is fundamental failure of their ANC algorithm. There's basically no protection mechanism incase of divergence.
- mvkel 1y agoIf it's an algorithmic issue, can that not be changed?
- garyfirestorm 1y agomy 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.
