Definitions

  • the technical solution relates to devices for protection against noise, and in particular to devices for absorbing noise, in particular, to protect populated areas from harmful sound exposure coming from highways and railways.
  • the prior art solution is an acoustic module made of two profiled sheets, perforated and solid, containing structural elements in the form of protrusions and their corresponding grooves for connection with each other.
  • the connected sheets form a space in which sound-absorbing material in the form of mineral wool is placed.
  • an acoustic barrier made in the form of a multilayer structure, including external perforated metal and metal whole sheets, with a sound-absorbing filler fixed between them.
  • Distinctive features of the proposed solution are: between the sound-absorbing filler and the metal perforated sheet, a moisture-proof membrane is fixed;

  • a sound-absorbing filler is fixed between the sheets, coated on all sides with fiberglass and a breathable moisture-proof film, and fixed to the whole sheet with rubber glue.
  • the perforated sheet is fixed to the structure without the use of glue, with the exception of its end surface.
  • an acoustic barrier made in the form of a multilayer structure, including external perforated metal and solid metal sheets, with a sound-absorbing filler fixed between them;
  • a moisture-proof membrane is fixed between the sound-absorbing filler and the metal perforated sheet.

  • - sound-absorbing material is fixed on one side to a moisture-proof membrane, and on the other to a metal whole sheet by means of polyurethane foam glue;
  • sound-absorbing filler is made on the basis of basalt.
  • the perforated sheet is fixed with a sound-absorbing material wrapped in a glassy and moisture-proof film by means of a special element in the form of a cover.
  • the disadvantage of this device is the complexity of its assembly, since it is necessary to use an additional element.
  • sound absorption by the perforated sheet will be difficult since it is not an outer surface.
  • the technical result of the claimed technical solution is manifested in improving the operational characteristics of the acoustic barrier due to the fact that the moisture-proof membrane is fixed to the perforated metal sheet by means of a discontinuous layer of water-based acrylic adhesive, which facilitates the passage of sound waves through the perforation of the sheet, while maintaining the moisture-proof properties of the membrane, ensuring durability sound-absorbing filler.
  • the technical result is achieved by the fact that in the acoustic barrier, made in the form of a multilayer structure, including external metal perforated and metal one-piece sheets, with a sound-absorbing filler fixed between them, while a moisture-proof membrane is fixed between the sound-absorbing filler and the metal perforated sheet, according to the claimed solution, a moisture-proof membrane fixed to the perforated metal sheet by means of a discontinuous layer of water-based acrylic adhesive, and the sound-absorbing material is fixed on one side to a moisture-proof membrane, and on the other to the whole metal sheet by means of polyurethane foam adhesive.

  • the intermittent layer of water-based acrylic adhesive allows you to easily and firmly fix the moisture-proof membrane, without losing its properties, to the perforated metal sheet.
  • Water-based acrylic adhesive has a safe and non-toxic composition, since solvents are not used in its production, and quickly hardens, fastening the moisture-proof membrane with a metal perforated sheet.
  • the discontinuity of the layer facilitates the passage of sound waves through the perforation of the sheet, which is not filled with glue, and their further absorption by a sound-absorbing filler, and also provides vapor permeability to the membrane, i.e., does not prevent the removal of water vapor from the space of the acoustic barrier and sound-absorbing filler.
  • Polyurethane foam glue by means of which sound-absorbing material is attached on one side to a moisture-proof membrane, and on the other hand to a metal one-piece sheet, is quick-drying, provides additional sound insulation.
  • An external metal perforated sheet with a multilayer structure is necessary for trapping and damping sound waves emanating from noise sources.
  • Sound-absorbing filler reflects and scatters sound waves transmitted through a perforated metal sheet, as well as their absorption, converting their energy into internal thermal energy of the medium.
  • the metal one-piece sheet isolates the sound waves, directing them to the sound-absorbing filler, thereby reducing the noise level in the space enclosed by the acoustic barrier from the noise source.
  • a moisture-proof membrane is necessary to protect the sound-absorbing filler from moisture and wind.
