Decoding the Mystery of Noisy Carbon Wheels
The whoosh-whoosh sound produced by carbon wheels is a result of resonance, which is influenced by construction methods, materials, and cavity volume. Deep-profile rims are louder because they have a larger surface area that can vibrate and move air to create noise. Construction techniques, such as tension in the sidewall or disc brake wheel skin, also affect the loudness of the wheels. Additionally, the use of low-temperature resins with rubber or elastomer additives in modern wheels increases damping and reduces noise. Tubeless tires and disc brakes also play a role in reducing wheel noise.
