Mobile terminal booth, masking system and masking sound generation method with sound masking function
A mobile terminal booth with a sound masking function includes a sound absorbing panel which partitions a space as viewed from the above to provide a place where a user of a mobile terminal can have a telephone conversation; a speaker provided to emit sounds to an outside of the mobile terminal booth; and a masking sound generation unit provided to emit a masking sound through the speaker. The harsh-sounding high frequency components of the masking sound are attenuated so that the masking sound gives less uncomfortable feeling to persons surrounding the mobile terminal booth. This masking sound is generated by attenuating a high frequency component of a raw sound material including a natural sound.
