This application describes systems and methods for locating, securing, accessing and utilizing a discrete enclosure or workspace. The discrete enclosure or workspace may be located in a public, private or semi-private setting and may comprise a combination of working platforms or surfaces, seats, desks and other apparatus, as well as computer hardware and software. Systems may comprise natural language processing, artificial intelligence, machine learning and other adaptive learning capabilities to enhance the use of the discrete workspace. The workspace may be dimensioned to be used for a wide variety of activities by one or more users.

A freestanding booth comprising a plurality of upstanding peripheral walls, a roof and a base upon which the booth stands in use, one of the walls defining an opening that is closed by a door, wherein the base extends along a basal edge of a plurality of the walls but does not extend across the opening.

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 which is output from the speaker are attenuated so that the masking sound gives less uncomfortable feeling to persons surrounding the mobile terminal booth.
