I agree - but I only suggested antiphase noise cancellation since I can't recall having read a discussion on this board about it, and I've been reading since the beginning. I'm pretty sure I would have remembered something like that on the board, as it interests me - I have been looking at doing exactly this with a Mk2 (if I ever get one ). Did I miss something interesting? Can you point me to the thread?

I think you would be better with speed-sensitive level control, with a base level setting; this would avoid ambarrassment when you are stopped by the coppers in heavy traffic ("What did YOU SAY OFFICER? Sorry about this IT JUST KEEPS GETTING LOUUUDDDDEERRR!") - a closed loop, positive feedback situation. IIRC, there is supposed to be a wire definition (rarely used) in the ISO connector definition for level control for just this - allowing a unit to sense speed.

Even if you implemented this, then surely you want the level to be set relative to what the driver can hear at his hearing position - so I'd stick by the microphone in the seat's head restraint as being the perceived audio level relative to which you want to set the volume to get a fixed dB(A) delta. This does strike me as somewhat dangerous to the health of your hearing and also your amp...

Plus, if you boost volume in response to ambient noise levels, then what happens when you try to use the long-awaited VR? You speak to your Empeg, and it boosts the volume as the VR software is trying to recognise phonemes, thus reducing the S/N ratio and making it progressively more difficult to tokenise the longer you speak.

And what about just talking to someone in the car - it would get progressively louder as it integrates with time and you'd end up screaming at the person next to you if you can't find the remote in time....
