Title:
PORTABLE TERMINAL BOOTH PROVIDED WITH MASKING FUNCTION, MASKING SYSTEM, AND MASKING SOUND GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/079761
Kind Code:
A1
Abstract:
Disclosed is a portable terminal booth comprising a sound-absorbing panel inside which a usage space for a mobile terminal is formed by partitioning the space in a plan view, a speaker provided facing to the outer side of the usage space, and a masking sound generation device that causes a masking sound to be generated from the speaker. A harsh upper-register range is attenuated by the masking sound, and discomfort that people in the periphery of the portable terminal booth experience due to the masking sound can be alleviated. Preferably, the masking sound is generated by attenuating the upper-register range of source sounds including natural sounds.
