Naw, I think they are even a bit louder than blues.

Browns are nearly silent. You're maybe comparing to the noise of bottoming-out the keys (and popping back up), which is still fair, because that's still keyboard noise, just not really the switch itself.

Also I'd say that the higher force requirement is more of an issue than the noise (unless someone living with them dislikes the noise). I'm not saying that the higher force is a significant problem either, I'm sure some people prefer it, I just think it's unoptimal (could add to fatigue or RSI, or be 1% worse for gaming)
