This has only started recently in like the past 2 or 1 weeks but whenever i use any of the anc features (adaptive, transparent, noise cancellation), my left airpod keeps on making some really weird annoying noise. Like as soon as i change to one of the options which usually makes another noise as well but thats normal ofc, the beep will also start and then it keeps on repeating after like 5 or 10 seconds. Any fixes?

So for my 1300 practical exam we need to use an oscilloscope and circuit breadboard admittedly I have gone to like none of the practical classes. Is there anywhere on campus where we can practice with such materials I could use out of class? I heard UQ innovate has some?
