- the front surface of the main body is provided with a sound-absorbing soundproof panel, characterized in that the recessed portion, the convex portion and a plurality of sound absorbing holes are formed along the vertical direction.
- the sound-absorbing soundproof panel according to the present invention can be variously applied to architectural and industrial products, has good sound absorption characteristics for a wide frequency band, and can produce a beautiful appearance effect.
- the sound-absorbing soundproof panel according to the present invention can be manufactured by integrally molding by extrusion molding, easy to manufacture and construction, made of synthetic wood appears natural texture, has excellent water resistance and weather resistance.
- FIG 1 and 2 are cross-sectional views of a sound absorbing soundproof panel according to an embodiment of the present invention.
- Figure 3 is a perspective view of a sound absorbing soundproofing panel according to an embodiment of the present invention.
- Figure 4 is a perspective view of the cut away sound-absorbing soundproof panel according to an embodiment of the present invention.
- FIG 1 and 2 are cross-sectional views of a sound absorbing soundproof panel according to an embodiment of the present invention
- Figure 3 is a perspective view of a sound absorbing soundproofing panel according to an embodiment of the present invention
- Figure 4 is according to an embodiment of the present invention The cutaway perspective view of a sound absorption type soundproofing panel.
- the sound absorbing soundproofing panel 1 includes a main body 10 and a sound absorbing material 20 disposed in the main body.
- the main body 10 has a front surface 11 and a rear surface 15 and extends along a horizontal direction, and spaces 30 and 40 are formed between the front surface 11 and the rear surface 15.
- the recessed portion 12 and the convex portion 13 are alternately formed along the vertical direction, a plurality of sound absorbing holes 14 are formed, the main body 10 is an olefin Compound formed by mixing a series of plastic resin and wood flour can be manufactured integrally by extrusion molding, the front surface 11 having an uneven structure represents a louver shape, and the spaces 30 and 40 play a role of damping noise. do.
- the recessed portion 12 and the convex portion 13 may be formed with a plurality of irregularities on the surface, thereby the diffuse reflection occurs on the surface it is possible to obtain the effect of dissipating noise.
- the sound absorbing hole 14 serves as a Helmholtz resonator, and the shape of the sound absorbing hole 14 may be determined in consideration of sound absorbing performance and appearance effects, but is not limited thereto.
- a slit or It may be circular.
- the diameter of the sound absorbing hole 14 may also be determined in consideration of sound absorbing performance, and the total area of the sound absorbing hole 14 is preferably 20% or more of the total area of the front surface 11 for high sound absorbing performance. At this time, if the total area of the sound absorbing hole 14 is lower than the above-mentioned value, the sound-absorbing performance is lowered. If it is larger than the above-mentioned value, there is no particular limitation, but it is preferably 30 to 40% or less in view of appearance effects.
- the sound absorbing material 20 may be formed of a material having excellent sound absorption or sound insulation performance, but is not limited thereto.
- a material having excellent sound absorption or sound insulation performance for example, polyurethane foam, polyurea foam, polyvinyl chloride foam, polypropylene foam, polyethylene

- KSF 4770-3 which is the current KS standard
- the sound absorption rate of 250 Hz, 500 Hz, 1000 Hz, and 2000 Hz is defined to satisfy 0.7 or more. Therefore, the second resonance in the sound absorbing soundproof panel according to an embodiment of the present invention is satisfied.
- the portion 40 has a resonance structure at 500 to 1000 Hz
- the sound absorbing material 20 is preferably formed of a material having a high sound absorption rate at 1000 Hz or higher.
- a frequency band for attenuating noise is determined according to the area of the sound absorbing hole 14 and the volume of the first resonance unit 30, and the sound absorbing soundproof panel according to the embodiment of the present invention is provided.
- (1) by having two resonance structures 30 and 40 by one sound absorption hole 14, high sound absorption performance is shown.
- the front 11, in particular the main portion 12 and the rear surface 15 of the main body 10 are each formed with a reinforcement protrusion (R) protruding inward, respectively, such a reinforcement projection (R) is a sound-absorbing soundproof panel 10 It contributes to the structural stability of, and partitions the first and second resonators 30 and 40 into a plurality of spaces.
