Latest Patents

Tao's latest patents include a signal processing device, a sound-reproduction system, and a sound reproduction method aimed at enhancing the attractiveness or recognition of sounds, such as engine sounds. The signal processing device comprises a processor and a memory with specific instructions. These instructions enable the device to perform modulation processing of sound signals using modulation parameters based on interaural phase differences at the listening position.

Another notable patent is the active noise reduction device and method. This device includes a standard signal generator, adaptive filters, a control sound emitter, and an error signal detector. The standard signal generator produces a standard signal that includes harmonics of a fundamental frequency correlated with the control target sound. The adaptive filters generate corresponding harmonic components of a control signal based on the standard signal. The control sound emitter then emits a control sound based on this control signal, while the error signal detector collects residual noise and detects an error signal based on it.
