Are carbon wheels still noisy?

I test rode bikes with carbon wheels (around 40mm and 50mm wheels) two years ago and the wheels made it sound like you were riding a fully wooden wheels. Do all new carbon wheels sound the same? I really like the look of fully black wheels but don't like the extra sound carbon wheels make so I've also been thinking about Mavic Ksyrium SLR WTS. But those cost about twice as much as chinese carbons :p

If you want quiet braking you should go with an alloy rim, or go disc.

If you mean the hollow sound of carbon rims, shallower ones will have that less than the deeper ones.

If you mean squealing, lots of people, including myself, have had success using Reynolds blue pads on "generic" carbon rims. But of course SwissStop has been busy too, since the yellows have been introduced -- I've just not tried anything newer from them, because Reynolds are cheaper and perform good enough. A lot depends on the brake caliper, too. Stronger (often heavier) ones many times work better and vibrate less -- less noise.

I mean the hollow sound. I would get 38mm wheels max. Is there big difference in sound between 38mm and 50mm?

I live in pretty flat country so I'm not that worried about the braking sound.

I'm no expert, but all carbon wheels seem to be louder. Why, my guess is that with the thinner material for the same strength, it would be more like a drum. Since noise is just a vibration you can hear, the thinner material just vibrates a little more in a range you can hear.

Again, I'm no expert and can just barely even ride a bike.

I routinely ride sets of shallow alloy, 45mm deep carbon and 65mm deep carbon wheels. While the alloy wheels are somewhat quieter, I would never say that the 45 or the 65 are terribly loud. I think the sound may vary based on whether the carbon on the wheel is a fairing or structural (could be wrong), but regardless never found them to be terribly offensive.

When I am going properly my breathing is loader than the hollow sound and so is the wind noise and the tyre noise.

If it's that much of a bother, you could investigate some foam-core rims.

Have to look on those.
