Yoichi Uehara

Title: Yoichi Uehara: Sound Signal Processing Inventor.

Introduction

Yoichi Uehara is an inventor associated with Kanagawa, Japan, and Sony Corporation. His work includes an invention for sound signal processing designed to improve perceived loudness while keeping the correction algorithm simple.

Latest Patents

Uehara is credited with 1 patent: “Sound Signal Processing Apparatus and Sound Signal Processing Method.” The invention defines correction steps ranging from correction off, with a level correction value of zero, to a correction value of −16 dB. When a condition associated with distortion is met, the system advances one step and adds 1 dB to the level correction value. When a condition indicating that distortion is absent is met, it moves back one step and subtracts 1 dB. This stepwise approach aims to provide a satisfactory perceived sound volume and effective correction with a straightforward algorithm.

Career Highlights

Uehara’s listed patent work is associated with Sony Corporation, a company known for developing and commercializing audio technologies. His sound-processing invention addresses the balance between perceived loudness and distortion through incremental level adjustments.

Collaborations

Kohei Kanou and Shinji Hirose are identified as Uehara’s coworkers. Their names are also associated with the collaborative context of his patent work.

Conclusion

Yoichi Uehara’s patent describes a practical, step-based method for adjusting sound levels in response to distortion conditions, reflecting his contribution to audio signal processing at Sony Corporation.
