The system has at least one apparatus for detecting a noise, a computer unit for calculating a compensation sound, at least one apparatus for generating a compensation sound which interferes with the noise, and a device for detecting at least one driver-specific parameter. The compensation sound is calculated depending on the at least one driver-specific parameter. Also provided is a motorcycle having a system for active noise compensation. ## Claims ### Claim 1 An active noise compensation system for a motorcycle, comprising: a noise-capture unit configured to capture a noise near a driver of the motorcycle;
