    摘要： Disclosed is a sound absorption plate with a unit structure. The sound absorption plate comprises an ultramicropore sound absorption front plate (1), a side plate (2) and a sound absorption back plate (3). Edge parts of the ultramicropore sound absorption front plate (1) are connected to the sound absorption back plate (3) through the side plate (2), thereby forming a sound absorption resonant cavity (4). The material of the ultramicropore sound absorption front plate (1) is a metal material carrying nano microspheres (5). A sound absorption metal thin film (6) carrying nano microspheres (5), parallel to the ultramicropore sound absorption front plate, is disposed inside the sound absorption resonant cavity (4). A pore size of the nano microspheres in the ultramicropore sound absorption front plate (1) and the sound absorption metal thin film (6) is 100-1000 nm. The sound absorption plate has a simple structure, simple and convenient manufacture and assembly, a wide sound absorption frequency band and a good noise reduction effect, and is suitable for ceiling and wall decoration of buildings.

    摘要： [Abstract] A mobile terminal booth which provides an area where a mobile terminal can be used in a public place is described. This mobile terminal booth is provided with a sound absorbing unit which is placed in a public place and partially partitions a space as viewed from the above where a user of a mobile terminal can have a telephone conversation. The sound absorbing unit is made of a laminate consisting of a plurality of sound absorbing layers. The sound absorbing layers are joined together in the form of the laminate with a viscous adhesive which does not solidify after formation of said laminate, and maintains its viscosity when the mobile terminal booth is used.
