oh yes active noise cancellation. I been working with sound equipement a long time🤓.
the signal is split in 2. one is phase inverted. the other is delayed so that the positive and inverse signal are synchronized. noise signal + its opposite equals zero.
either the app wasnt that good at doing the job, or having the noise in your ears and the inverse in headphones doesn’t work… maybe somebody will come up with a better app😉
I wish we could just hookup a feedback exterminator to our head, but that would never work . (lot of work for the people that design them, but very easy to use… even pro equipement is mostly just plug n play) fb x sends a signal through the system. It knows the dB of the signal sent. If the signal going back through the box is increasing in strength it blocks that frequency.
I have noticed that when I am not actively paying attention the tinnitus faded in the background. but if I listen to one of those frequency vids on yutube: alpha, beta, delta, sophegio the volume of the tinnitus increases. Its like the tinnitus takes any kind of mantra or frequency as a challenge to its supremacy. Maybe if Dark knight gets a mantra for tinnitus it works, and maybe it will be like a PA system inside my head
