MASTER CONTROL METHOD FOR ONE-WAY TRANSMISSION OF SOUND

WIPO Patent Application WO/2023/060730

A1

A master control method for one-way transmission of sound, comprising the following steps: S1, selecting a space surface, and obtaining mass point sound pressure p on a sound wave plane and a vibration velocity u in a sound transmission direction A needing to be controlled; S2, locking sound pressure on the sound wave plane according to the mass point sound pressure p, and locking a vibration velocity on the sound wave plane according to the vibration velocity u; and S3, when a sound wave passes through a medium, due to locking relationships in step S2, characteristics of one-way transmission of the sound being presented in the sound transmission direction A of the space surface. One-way transmission control of a sound wave is achieved by locking the sound pressure and the vibration velocity, and the method is not affected by working frequency bandwidth and not limited by the space size and thickness, and has excellent popularization and application value.
