AI Technical Summary
Existing active noise cancellation systems in vehicles fail to adapt quickly enough to head movements, leading to undesirable spatial variations in noise cancellation, particularly at high frequencies, due to the slow adaptation rate of systems like RNC and EOC.
Incorporating a head tracker sensor to provide real-time updates to the transfer function between microphones and remote microphone locations, allowing for continuous adjustment of anti-noise signals based on the user's head position, thereby enhancing the adaptability of the noise cancellation system.
The system effectively minimizes noise cancellation artifacts caused by head movement by dynamically adjusting anti-noise signals, ensuring consistent and improved noise reduction across different head positions, especially at high frequencies.
