５で吸収されると共に吸音ベース材１に吸収される。EXAMPLE A sound absorbing composite panel A of the present invention is formed by adhering a breathable thin film body 6 to a sound absorbing base material 1 and a surface plate 2 to the thin film body 6 as shown in FIGS. ing. The sound absorbing base material 1 is an inorganic porous material such as rock wool or glass wool, a synthetic resin foam such as urethane foam,
It is made of steel wool, aluminum foam, etc. Concavities and convexities 4 are randomly provided on one surface of the sound absorbing base material 1, and a large number of internal sound absorbing holes 5 which are not penetrated are punched from one surface of the sound absorbing base material 1. Examples of the breathable thin film body 6 include non-woven fabric, fibrous cloth, woven fabric, breathable paper and synthetic resin sheet. The thin film body 6 is superposed on the sound absorbing base material 1 and adhered to the convex portions 4b of the irregularities 4 by the adhesive layer 7. The surface plate 2 has a large number of external sound absorbing holes 5, and is a perforated plate, a mesh plate or the like. The material of the surface plate 2 is lauan plywood, solid wood, wood material such as medium density fiberboard, Examples include synthetic resin materials such as urethane and acrylic, metal materials such as aluminum, stainless steel and iron, inorganic materials such as gypsum board, calcium silicate board and slate board. The surface plate 2 is superposed on the thin film body 6 and adhered by an adhesive layer 7. The sound absorbing composite panel A thus formed is used as a ceiling material or a wall material for an acoustic room or the like. Then, the sound is absorbed through the external sound absorbing hole 5, is absorbed by the thin film body 6, the concave portion 4 a and the internal sound absorbing hole 5 and is also absorbed by the sound absorbing base material 1.
