Latest Patents

Basu's latest patents include a "System and method for estimating secondary path impulse response for active noise cancellation." This innovative system enhances ANC performance in a near-imperceptible manner by utilizing music signals as test signals and ANC error microphones to estimate the secondary path impulse response. The system ensures that the music signals have sufficient audio content to be considered adequate test signals. Additionally, it employs advanced signal processing to obtain a unique impulse response for all speakers and microphones, allowing for real-time calculation of new coefficients for the ANC system.

Another notable patent is the "System and method for secondary path switching for active noise cancellation." This ANC system involves an audio signal source that provides an audio signal, while at least one loudspeaker projects anti-noise sound within a cabin. The system utilizes microphones to provide error signals and employs a controller to estimate and compare impulse responses, ultimately generating an effective anti-noise signal.
