We utilize our proprietary spatial active noise cancellation algorithm, combined with microphone components, in-vehicle audio systems, and various sensors, to cover noise frequencies ranging from 0 to 2000Hz. This technology effectively reduces road noise, tire noise, wind noise, and chassis noise within the cabin.

By using holographic sound field control, the in-car sound field is partitioned into multiple zones. The same speakers can deliver different signals as needed and direct them to various listening positions. This allows for independent sound field partitioning throughout the car, enabling a voice interaction mode where the driver, front passenger, and rear passengers do not interfere with each other. It creates a more comfortable and private listening environment, catering to passengers' personalized needs.

This solution can create an unexpectedly expansive sound field within compact vehicles. During spatial audio playback, the sound is centered around the user, dynamically adapting to their movements. It accurately presents a vast three-dimensional sound field, restoring a musical experience that enhances the sense of presence, distance, direction, and motion.

Upon detecting voice signals from rear-seat passengers, the system triggers the speakers embedded in the front headrests to emit adaptive counteracting sound waves. These waves cancel out the voice signals through phase interference, significantly diminishing the clarity and intelligibility of the conversation. As a result, up to 90% of the rear-seat dialogue is effectively masked, safeguarding passenger privacy. Additionally, this feature minimizes distractions for the driver, improving focus and overall driving safety.
