Default Ear piercing sound from B&O speakers when accelerating sometimes

I have a 2018 s5 technik. I noticed every now and then when accelerating, the speaker emits a short ear piercing noise. It only lasts a split second but it's enough to make my face cringe when I hear it. Sounds almost like a whisp but such a high frequency. Sometimes it'll happen only once on a 1 hour drive sometimes more often. It is extremely annoying and somewhat unsafe.

Driving in dynamic mode in S.

Has anyone seen, or should I say heard this before?

I don’t have an acceleration-related sound. However, after the Audi nav system interrupts audio with her verbal instructions, audio comes back on with a split second burst of high output before settling to its previous level. Kinda like it had pent-up pressure in the speakers (which I know doesn’t make sense). Perhaps they’re related...

Get those things checked while under warranty...
Those damn B&O speakers are ridiculously expensive to replace and they will blow in the conditions you outlined.
