There is no evidence that there will be noise cancellation for driver and passengers. I think some have gotten hopeful about it being a feature, but I don't think it will be. Read the wording carefully:Does anyone know what these are?
I think the mics are for reducing noise for people on the other end of the call, not for active noise cancellation inside the Rivian itself. There are also no mentions of noise cancellation on the Meridian pages for the R1T and R1S.While there’s no engine noise to contend with, an integrated beam-forming mic array in the headliner still offers noise reduction and echo cancellation during phone calls in noisy environments or when the windows are down.
Jaguar-Land Rover uses Meridian audio but is using a separate chip from Silentium to provide the processing needed for ANC. I don't think Meridian has the tech to do it on their own, and Rivian would need to add their own processing or add a chip like the Silentium ones that JLR is using. Since they're not talking about it, I assume it will not be a Rivian feature.
