Application: A method for automatically designing a feedforward filter (Patent ID: US20240071350A1)

The patent filed by Renesas Electronics Corp. describes a computer-implemented method for automatically designing a feedforward filter optimized for an audio transparency mode of operation in an audio device. The method involves optimizing the feedforward filter based on the feedback filter, determining properties of the feedforward filter, such as the transfer function, and compensating for the passive frequency response of the audio device to enhance audio transparency. The process includes acquiring and averaging various transfer functions, ensuring stability of the feedforward filter, and optimizing the feedback filter before the feedforward filter.

Additionally, the patent includes an automatic feedforward filter design tool for optimizing the feedforward filter in an audio device that operates in audio transparency and noise cancellation modes. The tool is designed for use in headsets, headphones, hearing aids, or personal amplification devices. It emphasizes the interdependence of the feedforward and feedback filters in achieving optimal performance in the audio transparency mode, providing a systematic approach to designing and implementing these filters for enhanced audio quality and transparency in various audio devices.
