AI Technical Summary

Technical Problem

Existing vehicle noise reduction technologies only address specific noise types, resulting in limited effectiveness. They cannot meet the noise reduction needs of different scenarios or provide a differentiated cabin experience.

Method used

Noise partitioning is performed on the in-vehicle audio signals collected by the in-vehicle microphones to identify multiple in-vehicle noise areas; noise classification is performed on the out-of-vehicle audio signals collected by the out-of-vehicle microphones to identify multiple types of out-of-vehicle noise; based on the noise in each in-vehicle area and the various types of out-of-vehicle noise, the target type of noise to be suppressed is determined, and a suppressed audio signal is generated.

Benefits of technology

It enables flexible determination of target noise type based on different scenarios, generation of suppressed audio signals, suppression of target noise type in in-vehicle audio signals, and provision of a quiet cabin environment.
