  • the body with the open cell structure may be formed by a board of a foam material or a board of a web of bound polyester fibres with at least 50% of fibres perpendicular to the direction of the sound propagation.
  • the disadvantage which prevents the widespread use of the above described sound absorbing means is especially their appearance from the view side and a danger of damage to the acoustic resonance membrane, which is arranged on the view side of the sound absorbing means as well.
  • Another disadvantage is the fact that cleaning their view side is difficult and, moreover, during cleaning there is a danger of damage to the acoustic resonance membrane.
  • the aim of the invention is to remove these shortcomings and to develop a sound absorbing panel which can be cleaned without a danger of damage to the acoustic resonance membrane and whose appearance would match the environment in which it is to be placed and which would develop its aesthetic value.
  • the aim of the invention is achieved by a sound absorbing and thermal insulation panel, the principle of which consists in that the carrier body with the acoustic resonance membrane is situated inside a cover from a permeable textile material which covers it tightly without any deformations or twisting of the carrier body with the acoustic membrane.
  • a closeable opening is formed on the side of the cover.
  • the cover For reinforcing the cover, it is advantageous if on the sides adjacent to the closeable opening reinforcing means which can be fixed on the carrier body and/or the cover are arranged inside the cover. At the same time, it is important that the closing element of the opening does not cause deformations of the carrier body with the acoustic membrane, neither does it cause the deformations of the cover.
  • a zip or a Velcro-type fastener appears as the most suitable means for this purpose.
  • the textile material of the cover is chosen from a group of fabrics, knitted fabrics or non-woven textiles with permeability higher than 20cm/s in pressure gradient of 100 Pa.
  • the carrier body is formed by a board from a foam material with the open cell structure and the board can be provided with an embossed pattern on the front view side. It is necessary to use pure soft silk, soft kinds of satin and damask or other similar soft material as a cover of such a board.
  • the carrier body is formed by a board of a web of bound polyester fibres with the open cell structure.
  • the openings are created in the board of the carrier body.
  • Another suitable method of fixing of the sound absorbing panel is its hanging in space, on the wall or in other suitable place.
  • the panel is provided with means for its hanging, for example a lug, tapes, etc.
  • the carrier body is formed by narrow bands placed individually in the cover and arranged in a vertical curtain.
  • the bands can be placed separately in the common cover and arranged in a folding manner.
  • Fig. 1 schematically represents an embodiment of the cover with a closeable opening for inserting the carrier body
  • Fig. 2 schematically represents an embodiment of the cover in the form of a band in which the carrier body is covered.
  • a sound absorbing and thermal insulation panel contains a cover 3 made from a permeable textile material which tightly covers a carrier body1 with an acoustic resonance membrane 2, which is formed by a layer of polymer nanofibers of 20 to 200 nm in diameter and which is in the form of a plane layer situated on the surface of the carrier body made of a sound absorbing and thermal insulation material over at least one free space created in the carrier body 1.
  • the free spaces in the carrier body 1 are in the advantageous embodiment formed by an open cell structure of a porous material which contains pores passing through the entire thickness of the carrier body
  • the cover 3 is formed as a hollow rectangular parallelepiped of the sizes corresponding to the sizes of the carrier body 1 with a closeable opening for inserting the carrier body in the cover 3.
  • the cover 3 is in the place of the closeable opening provided with flaps 31 ⁇ which overlap each other for closing the opening and are provided with connecting means for a repeated closing/opening of the opening, for example, for cleaning or washing the cover 3 when it is necessary to take the carrier body ⁇ out of the cover 3 and after cleaning or washing insert it in the cover again and close it.
  • the connecting means are chosen from a Velcro-type fastener, zip, magnets and connections which can be repeatedly attached to one another.
  • flaps 31 can also be connected by sewing or one flap can be created and sewed along the perimeter of the opening, etc. It is also possible to use other known connecting means.
  • reinforcing means which prevent the carrier body ⁇ from bending, can be inserted on at least two opposite sides of the cover.
  • the reinforcing means can be fixed on the carrier body 1 or they can be fixed on the cover 3_or they can be, after inserting the carrier body 1 in the cover 3j inserted between the cover 3 and the carrier body ⁇ before closing the opening.
  • the cover 3 is formed by a band of a permeable textile material which is placed on the front surface of the carrier body provided with an acoustic resonance membrane 2 and wrapped around two side walls of the carrier body ⁇ and both sides of the bands are on the back side of the carrier body 1 connected to one another by means of connecting means.
  • the reinforcement means can be placed between the side walls of the carrier body ⁇ and the cover 3.
  • flaps 31, which close the cover 3 around the carrier body 1_ are formed on the band of the cover 3.
  • the flaps 3J. are, as well as in the previous embodiment, provided with connecting means.
  • the textile material of the cover 3 is chosen from a group of fabrics, knitted fabrics or non-woven textiles having permeability higher than 20 cm/s in pressure gradient of 100 Pa.
  • a work of art or decoration can be created, for example a tapestry or art protis. Then it is important to pay attention to the highest possible permeability of this work of art or decoration so that the sound absorption quality of the panel is not lowered too much.
  • the carrier body is formed by a board of a foam material with an open cell structure.
  • the carrier body ⁇ can be provided with an embossed pattern on the front view side, on which the acoustic resonance membrane is situated.
  • the cover 3 in made of a soft silk or satin.
  • the carrier body 1 is formed by a board of a web of bound polyester fibres with an open cell structure.
  • openings can be formed in the board of the carrier body ⁇ and covered with an acoustic resonance membrane 2 formed by a layer of polymer nanofibers or a board of other than the above described material can be used, in which openings covered by an acoustic resonance membrane 2_are created.
  • the sound absorbing and thermal insulation panel is most frequently designed to be placed on the peripheral walls of a room.
  • the Velcro-type fastener makes it relatively easy to remove the panel from the wall and to install it repeatedly, for example after cleaning or washing.
  • the carrier body is peripherally shaped accordingly and the cover 3 is individually adjusted to this shape.
  • the panels are equipped with means for the arrangement in space, for example stands, legs or other means for standing on the floor when the panel can be placed in any suitable frame or means for hanging which can be formed by ceiling consoles, rails with corresponding sliders or tapes or other suitable means.
  • the carrier bodies 1_ can be formed by bands placed individually in a cover 3 and arranged in a vertical curtain.
  • the width of the bands can vary and is dependent on the space in which the panels are to be used.
  • the carrier bodies 1 formed by bands placed separately in a common cover 3 which is between the carrier bodies ⁇ stitched through, pressed or otherwise joined and the individual parts are arranged in the folding manner.
  • the carrier body is formed by a wide band of web of bound polyester fibres or another suitable material with an open cell structure placed in a cover 3 which is in the places of the required bends creating the folding stitched through, pressed, attached or arranged otherwise so that these bendings are made possible.
  • the sound absorbing and thermal insulation panels provide an easy arrangement of any interior, in case of the hotel or office spaces it is not necessary to stop the operation or block using the rooms because of installation or subsequent cleaning.
  • the sound absorbing and thermal insulation panels can be used for facing walls and ceilings of rooms. Furthermore, they can create divisions in rooms, for example in open space offices, means of transport, for example in planes, buses and trains. Other applications can be used in upholstery, where with the help of panels, in particular of a web, it is possible to adapt bedheads, doors, partitions, etc., and further adjust them by stitching through or buttons.
  • Another option is covering blank parts of plastic windows, where the panel is placed on the untransparent part of the window.
