Sound field optimization method for intelligent cockpit audio system
A recently granted patent (Publication Number: US12003947B2) discloses a sound field optimization method and device for an intelligent cockpit audio system. The method involves building acoustic response models based on audio parameters and transfer functions for speakers located in different areas of the rear seat, controlled and uncontrolled by a rear passenger. By calculating optimal audio parameters to maximize the acoustic response difference between these areas, the method aims to enhance the audio experience for passengers. The device includes building blocks for creating acoustic response models, a calculation module for determining optimal audio parameters, and a control module for adjusting speaker output accordingly.
Furthermore, the patent details additional steps for optimizing the sound field, such as building acoustic response models based on ear positions and virtual speakers, as well as minimizing differences between actual and analog acoustic responses. The device is designed for use with speaker arrays positioned at various locations within the vehicle. By implementing these methods and devices, the intelligent cockpit audio system can tailor the audio experience based on the presence and positioning of passengers in the rear seat, ensuring optimal sound quality and distribution throughout the vehicle.
