Latest Patents

One of Sira's latest patents is titled "Systems and methods for modifying biquad filters of a feedback filter in feedback active noise cancellation." This invention involves an integrated circuit designed to provide an output signal to a transducer, which includes both a source audio signal and an anti-noise signal. The processing circuit implements a feedback path that generates a feedback anti-noise signal based on an error microphone signal. This system is capable of detecting ambient audio events and adjusting filter coefficients to minimize undesirable components in the anti-noise signal.

Another notable patent is "Systems and methods for active noise cancellation including secondary path estimation for playback correction." This device features a housing and a transducer that reproduces an audio signal, including both the source audio and anti-noise signals. The processing circuit utilizes a feedback filter to generate the anti-noise signal from a playback corrected error, which is based on the difference between the error microphone signal and a secondary path estimate signal. This innovative approach aims to minimize ambient audio sounds effectively.
