Latest Patents

Hamada's latest patents include an electronic noise attenuation method and an electronic noise attenuation system. The electronic noise attenuation method involves a technique for electrically reducing noise in a three-dimensional sound wave propagation area. This is achieved by creating a drive signal based on noise information and previously established filter coefficients using an adaptive digital filter. The system generates an additional sound wave to cancel out the noise effectively.

The electronic noise attenuation system is designed to mitigate sound waves from a noise source by producing another sound wave that is 180 degrees out of phase and matches the sound pressure of the original wave. This system utilizes electro-mechanical transducer means positioned within the sound wave propagation path to generate the necessary drive signals based on output from upstream and downstream transducers.
