AB  - Car audio systems aim to provide information, entertainment, and acoustic comfort to drivers and passengers in cars. In addition to basic audio functions for broadcasting, playing chimes, warning sound, and music, there are special audio features such as vehicle noise compensation, spatial sound effects, individual sound zone, and active noise control. In this paper, commonly used objective measurement methods for basic sound quality and special features in cars are reviewed and discussed. All objective measurements are proposed to use the 6-unit microphone array specified in the White Paper for In-car Acoustic Measurements released by AES Technical Committee on Automotive Audio in 2023, and the main parameters to be measured are frequency responses and sound pressure levels in the car when the specially designed test signals are played back. General measurement frameworks and procedures for basic sound quality and each feature are presented. The advantages and weakness of using these parameters to characterize the basic sound quality and special features of a car audio system are discussed, and the challenges and future directions are explored.
