Latest Research on External Sound Field Analysis Accepted at ICASSP 2026

We are proud to announce that research conducted by our team, Juliano Ribeiro, Ryo Matsuda, and Jorge Trevino, has been officially accepted for presentation at ICASSP 2026 (International Conference on Acoustics, Speech, and Signal Processing), which will be held in May 2026.

This research focuses on simplifying external sound field analysis, which involves estimating acoustic radiation characteristics by capturing differences in sound depending on the relative positions and orientations of sources and listeners. Traditional holography-based methods for exterior sound field analysis require precisely built microphone arrays covering all directions with a large number of channels. Their proposal reduces the cost and complexity of this measurement by enabling the accurate exterior sound field estimation from signals recorded by simpler, less constrained microphone arrays. After peer-review verifying the validity of our proposal, it was accepted for presentation in ICASSP 2026.

At Yamaha, we continuously measure and analyze the acoustic performance of musical instruments and audio products, integrating these findings into the design of our products to improve their quality and enhance the user experience. We remain dedicated to advancing acoustic technology and driving innovation in product creation.
