Title: Innovations of Hideki Hyoudo

Introduction

Hideki Hyoudo is a notable inventor based in Yokohama, Japan. He is recognized for his contributions to the field of electronic noise attenuation. His innovative approach has led to the development of a unique system designed to reduce unwanted sound waves.

Latest Patents

Hyoudo holds a patent for an "Electronic noise attenuation system." This system is designed to attenuate sound waves propagated from a noise source by generating another sound wave that is 180 degrees out of phase and has the same sound pressure as the original sound wave. The system utilizes electro-mechanic transducer means positioned in the sound wave propagation passage. A drive signal for the transducer is generated based on output signals from upstream and downstream mechano-electric transducer means. The drive signal is created by performing an operation on a difference signal between the output signal of the upstream transducer and the drive signal, according to a specified transfer function. The transfer function is determined based on the difference signal and the output signal of the downstream transducer.
