Title: Yasuhiro Terada: Innovator in Acoustic Technology
Introduction
Yasuhiro Terada is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of acoustic technology, holding a total of 4 patents. His work focuses on enhancing microphone technology, particularly in directional microphones.
Latest Patents
Yasuhiro Terada's latest patents include a directional microphone device and an acoustic signal processing method. The directional microphone device features a microphone that generates a first acoustic signal with sensitivity in a target direction, and another microphone that produces a second acoustic signal with a blind spot in sensitivity. A correction unit multiplies the second acoustic signal by the first acoustic signal to create a third acoustic signal, which narrows the angular range of the blind spot. Additionally, a suppression unit performs noise suppression using the first acoustic signal as the main signal and the third acoustic signal as a reference, resulting in an output acoustic signal with improved directivity.
Another patent focuses on a directional microphone apparatus and directivity control method. This invention corrects level and phase differences in low bands across multiple non-directional microphone units. The level difference calculation section computes the level difference between signals from two non-directional microphones, while the correction process section uses calculated coefficients to simultaneously correct these differences, enhancing directivity and reducing the overall size of the apparatus.
