Holographic Whisper: Rendering Audible Sound Spots in Three-dimensional Space by Focusing Ultrasonic Waves
CHI 2017 Paper
Abstract:
We propose a novel method of three-dimensional spatial audio rendering by expanding the ultrasonic phased array technique. We employ an ultrasonic phased array as a holographic acoustic generator to focus ultrasound at arbitrary three-dimensional positions. The sound pressure at the ultrasonic focal points is sufficiently high to radiate audible sound based on the self-demodulation effect in air. Consequently, the ultrasonic focal points act as audible sound sources. This sound-point method enables us to control aerial audio distributions more flexibly and more precisely in comparison with conventional superdirectional (sound-beam) loudspeakers. This method can generate and vanish the sound sources freely in air. These point sound sources can deliver private messages or music to individuals.

Why the EHTC made an artifact black image and how to obtain real black hole...ssuserf12200
This is a talk done in Autumn meeting 2020 of the Astronomical Society Japan by Miyoshi, Kato, Makino (in Japanese).
We showed the EHTC black hole shadow is an artifact by data samping bias.
Why the EHTC made an artifact black image and how to obtain real black hole...
