| titleOfInvention | SOUND PANEL |
| abstract | The solution relates to the field of construction, in particular to the use in construction as multilayer protective materials having, in particular, sound and vibration insulation properties; the panel is intended for use as a highly effective sound-absorbing and at the same time sound-insulating layer in building envelopes; the technical result is the elimination of the shortcomings of the closest analogue, expressed in the creation of material with improved soundproofing characteristics, in all areas of the normalized audible frequency range, with the possibility of using it as part of multilayer structures for additional sound insulation of existing and newly created building envelopes (external and internal walls, ceilings, floors); achieved by performing a soundproofing panel, which contains a rigid elastic layer (1) having a thickness of 5 mm ≤ δ 1 ≤ 50 mm and a density of 500 kg / m 3 ≤ γ ≤ 3000 kg / m 3 , to which at least on one side, a visco-elastic heavy damping layer (2) is attached, having a thickness of 0.5 mm ≤ δ 2 ≤ 20 mm and a surface density ρ 2 > 0.2 kg / m 2 depending on the material, while the coefficient of vibrational energy loss η 2 viscoelastic heavy damping layer (2) is greater than the coefficient of energy loss of oscillations of the hard elastic layer (1) η 1 . |
