An object of the present invention is to provide a sound absorbing and building acoustic control of a building space, and to provide a resonance sound absorbing structure molding and a building acoustic sound absorbing control structure assembled with a building interior material.

Resonant sound absorbing structure molding (Molding-resonant sound absorbing structure molding according to the present invention is referred to as molding for convenience in the present invention), each having a different size and in the forming portion of the bottom formed on both sides and side ends bent from the exposed surface to the bottom Construction using various interior plates assembled with moldings formed by resonance sound absorbing structures and moldings formed by resonant sound absorbing structures by inserting and installing sound absorbing materials that hide the sound absorbing holes formed on the bottom and conceal the sound absorbing holes formed on the bottom, and improve sound absorbing performance. It is to provide a sound control structure.

Molding in the interior of the building has a variety of design and functional uses, and interior molding has been used in various forms for a long time in Western architecture. Particularly, molding of molding design was used for the purpose of complementing the monotony of the enlarged interior space of large-scale palace construction or religious facilities, and for acoustic functional purposes. It is used for separation interface, and its size is also various. It is about 20 ~ 500mm wide, 10 ~ 200mm thick and its length is irregular. The cross-sectional shape consists of diagonal, flat and curved surfaces, and the large molding backing forms a space, and the surface is finished with sculpture or special coating. In Western architectures, there are many examples of large-size moldings (500-1000mm) formed at the corners of large holes, and the installation of this structure is characterized by the fact that the negative pressure concentrated at the corners It is considered that the functional advantage of dispersing the sound is considered.

In the present invention, the resonance sound-absorbing structure molding is configured for the purpose of providing a sound absorption control structure of the building, the molding is formed in a horizontal to vertical to diagonal to the wall surface or the ceiling surface of the open structure surface to form or atypical shape in consideration of the design Installed at a spaced interval, and installed on the exposed sound-absorbing structure molding and molding gap, gypsum board, plywood, MDF, wood material composite board, sound absorption board, tile, marble, metal plate, glass, interior It is a structure that diversifies the shape of resonant sound absorbing structure molding by inserting and combining building interior materials made of one or more materials from the composite board, and varying the shape of the resonance sound-absorbing structure molding. The length of the molding slit on both sides (depth) and the length of the molding in the field The inner surface of the inner plate, which is assembled with the molding, forms a plane or the end surface of the inner surface of the inner plate forms a diagonal surface and protrudes, so that the exposed surface can be installed as a curved curved surface of the diagonal surface. Resonance sound absorbing structure molding, which makes the structure of acoustic sound control structure that can adjust the reflection angle of sound arbitrarily, so that the sound diffusion, sound reflection angle control, sound pressure control and additional installation of sound absorbing material can be selectively installed on the inner plate surface. Architectural acoustic control structure has been provided.

The structure of the resonant sound absorbing structure molding is formed in the shape of the bumps and concave and slit (slit), scattering and dispersing the surface incident angle and reflection angle of the negative direct sound reflection sound, induces the sound diffraction incident on the slit surface to absorb some sound, Low frequency sound band through the resonance absorption structure of the present invention comprising a perforated hole forming a plurality of resonance absorption structures formed on the bottom surface, an open space formed on the back of the hole, and a porous sound absorbing material inserted into the open space. The internal plate, which is absorbed and assembled with the resonance sound absorbing structure molding, forms a flat diagonal curved surface to effectively control the flutter echo generated from the symmetrical surface and form an appropriate reflection diffusion structure of the sound. In addition, if the sound absorbing treatment is selectively added to the surface of the built-in plate to be assembled, the sound-absorbing coating and sound-absorbing putty, sound-absorbing paint (sound-absorbing paints of the applicant and registered patent application), sound-absorbing cloth, etc. As it can be installed additionally, it is possible to achieve sound control structure that is suitable for various acoustic sound spaces.

The type and characteristics of general acoustic sound absorbing materials in architectural acoustics are porous type absorptive materials, inorganic fiber boards, petrochemical organic fiber boards, natural fiber sound absorbing boards, wood fiber cement boards, and open air bubble pore structures. There are bubble sound absorbing blocks, and Resonator Type Absorption includes sound absorbing sound blocks, perforated plate sound absorbing materials made of various boards, and slit sound absorbing material using wood ribs, and plate vibration absorbing material (Membeaneous Type Absorption). It is divided into sound absorbing material using valves that cause vibration and membrane vibration.

As the sound absorbing property, the porous sound absorbing material is very effective for the sound absorption of medium frequency (400Hz-4000Hz) sound, and the sound absorption of low frequency (100Hz-300Hz) sound is insufficient.

The resonant structure type sound absorbing material uses a Helmolds type single resonator, which shows different effective sound absorption frequencies according to the volume inside the resonator, the length of the snout, and the diameter size of the snout. Resonance sound absorption effect in the 300Hz range.

Another resonant sound absorbing material is the application of the above Helmorts type single resonator structure, and a plurality of perforation holes penetrating the plane of the plate-shaped structure board are formed to arbitrarily adjust the opening ratio of the plane to about 3-30%. The higher the aperture ratio, the higher the sound absorption rate of the high frequency sound, and the densely punctured with a small hole in the thin plate increases the sound absorption rate of the high frequency sound. Perforating a thick plate to make the back of the air gun deeper (larger) effectively absorbs sound in the low frequency band. Therefore, it is a resonance structure-type sound absorbing material corresponding to the target sound absorption frequency band by controlling the space clearance of the rear side and the installation thickness of the porous sound absorbing material arbitrarily installed in the rear space.

The sound absorption characteristics of the resonant structure-type sound absorbing material are determined by the thickness of the plate, the hole diameter and spacing, the distance between the plate and the structural wall and the plate and the ceiling, and the sound absorbing material used for the back of the plate. The deeper the space between the plate and the back, the higher the sound absorption rate of the low frequency sound and the porous sound absorbing material inserted into the back, which can broaden the range of the sound absorption frequency.

Another sound absorbing material is a slit resonator, which also uses the principle of a resonator type sound absorbing material, which exhibits different bands of sound absorption frequencies controlled by changes in slit spacing, slit width, aperture ratio, and slit thickness.

There is another resonance structure sound absorbing mechanism and plate vibration resonant sound absorbing structure, which is a method of opening a specific position of the wall or ceiling to secure space or insert additional sound absorbing material. The sound energy is lost when vibrating, and the sound absorption function of the inserted porous sound absorbing material is used.

Technical classification can be divided into architectural acoustics for designing and constructing architectural acoustic spaces and electrical acoustics for installing and operating electroacoustic devices, and it is known that designing and constructing more desirable architectural acoustic spaces prior to electrical acoustics achieves natural optimal acoustic conditions. . In the operation of the electroacoustic equipment, the acoustic condition of sound absorbing reflections in the whole sound range should be properly adjusted. This is to design and construct the architectural acoustic space according to the size and shape of the architectural space to complete the desirable acoustic space.

Therefore, the goal of architectural acoustics is to achieve sound liveliness, create a distributed sound field, eliminate irritating high frequencies, uniform sound pressure distribution, remove low range booming, and adequate sound absorption and diffuse reflection.

Therefore, the resonant sound absorbing structure molding and the sound absorbing control structure of the present invention combine the resonant structure type sound absorption principle, plate vibration resonant sound absorption, diffraction sound absorption of sound, sound absorption characteristics of porous sound absorbing material, surface structure of interior material. Resonance sound absorption structure to utilize molding and sound absorption control structure to achieve.

When the resonator type sound absorbing material is used as a single structure, it is very effective for sound absorption of a specific frequency band of low frequency (100Hz-300Hz) sound and the sound absorption of high frequency sound is insufficient.

In addition, when the resonator type sound absorbing material has a larger hole, a different size, a more compact structure, and a porous type sound absorbing material on the back, low frequency (100Hz-300Hz) sound and medium high frequency (400Hz) -4000Hz) shows excellent sound absorption characteristics corresponding to a wider range of sound up to.

Since sound absorption control of architectural sound has to be adjusted over the entire sound range, most of professional sound space construction has overcome various sound absorption materials with different sound absorption characteristics. The materials of the sound absorbing material are broadly classified into glass fiber, mineral fiber, petrochemical synthetic fiber, wood fiber cement mixture, wood plate processed by resonance sound absorbing structure, wood processing acoustic rib, and perforated sound absorbing plate material.

These materials include rising production costs, limited design choices, fire safety and expensive acoustic sound absorbing materials, limiting the supply of raw materials, global warming due to logging of timber, and rising raw material supply prices. In addition, it presents a problem of creatively creating the inconvenience and surface finish design characteristics of mixed sound absorbing materials in order to utilize different sound absorbing properties. These materials have been used for decades in the architectural acoustics industry. In addition, it is unable to respond to artistic changes in fast-changing buildings, and in particular, the surface-finish design characteristics are limited to the well-formed conservative design that is repeated for a long time.

For example, the wood wool (wood fiber) cement plates used in the building acoustics industry are the same design for decades, and the wood plates processed with the sound absorbing structure are exposed to the surface with a number of surface perforations drilled with the sound absorbing structure. Glass fiber mineral fiber has a weak environmental durability and surface durability when exposed to the surface, and wood processing acoustic ribs have increased raw material supply price and supply limit, and petrochemical synthetic fiber has enhanced fire. It is vulnerable to safety (standard for use of interior finishing materials for building multi-use facilities). Perforated sound absorbing plate material is mainly made of MDF material with excellent workability, which is also unsuitable for enhanced fire safety.

Therefore, the present invention forms a resonance sound-absorbing structure for the purpose of improving the above problems, limiting the perforated hole to the molding bottom and is selected from the sound-absorbing material to the sound-absorbing cloth, sound-absorbing non-woven fabric to cover and conceal the bottom, the inner plate material and the inner plate material Resonance sound-absorbing structure moldings are assembled at intervals spaced apart and embedded into a space spaced from a plane made of a built-in plate material, so that the bottom surface of the sound-absorbing structure moldings is inserted 5 ~ 45mm more than the plane of built-in plate. To form a structure in which the perforated hole, the sound absorbing material to the sound absorbing cloth, and the bottom of the sound absorbing nonwoven fabric are concealed, and the molding structure forms a depth of 5 to 45 mm that is bent from the plane to the bottom direction, and the width thereof is 5 to 50 mm. Resonance sound-absorbing structure molding to form a slit shape that is bent from the plane to the bottom direction is the incident angle of the incident sound And scatters the reflection angle and induces the sound diffraction to form a sound absorbing structure that absorbs part of the sound. Then, the incident sound incident on the slit and the bottom passes through the perforations of the bottom perforated with different sizes. The sound energy is converted into thermal energy by viscous friction of air between the perforation hole and the inner space (back space) and partially extinguishes, and then provides an acoustic sound absorption control structure for sound absorption in the porous sound absorbing material inserted into the back space. In addition, the finishing process consisting of one or more materials among the paint, sound absorbing paint, sound absorbing cloth, sound absorbing board, and sound absorbing tile on the exposed plane composed of built-in plates has achieved the desirable sound control structure and new design pattern of the architectural acoustic space. .

In the present invention, as an effective sound absorbing means of low frequency (100Hz-300Hz) sound, a plurality of perforation holes are formed on the bottom of the resonant sound absorbing structure molding to form a Helmholtz resonant sound absorbing structure, and the perforations are formed at various sizes and at various intervals. It is composed of effective sound absorbing means of low frequency (100Hz-300Hz) sound by expanding the area of different sound absorption frequency according to the change of the interval and

In addition, as an effective sound absorbing and sound control means of the mid-frequency (400Hz-4000Hz) sound scattering and scattering the incident angle and the reflection angle of the incident sound in the slit portion bent in the direction of the molding bottom at the interior end of the plane and the molding surface The sound absorption structure is obtained by inducing sound diffraction and partially absorbing sound. The perforations of the molding bottom are formed in various sizes and at various intervals to enlarge the area of sound absorption frequency. The bottom surface is coated to expand the sound absorption efficiency of the high frequency sound, and the porous sound absorbing material inserted into the back space of the molding and the back space is constituted as an effective sound absorbing means of the high frequency sound. Sound control was achieved by selectively constructing the exposed surface angle of the surface into flat and diagonal surfaces.

In addition, for the additional sound absorption, by adding a finishing process made of one or more materials of the sound-absorbing paint, sound-absorbing cloth, sound-absorbing boards, sound-absorbing tiles to the exposed plane consisting of a built-in plate was configured as a selective sound absorbing medium of the high frequency sound.

In the prior art, Korean Utility Model Utility Model No. 20-0182637 introduces an acoustic block using expandable polystyrene, which is a structure that forms an uneven curved surface, which aims at uniform distribution of sound pressure and a distributed sound field.

The Korean Utility Model Model No. 20-0298648 is a resonance sound absorbing plate that forms a number of holes in plywood or MDF plate and consists of a surface panel, attaches a porous sound absorbing material to the back, and further attaches a perforated plate on the back, Difficult to diversify, perforated holes are exposed, multi-stage processing manufacturing process and the rise of the price of wood materials leads to an increase in manufacturing cost and lack of fire safety. The use of plywood MDF as a finishing material for buildings is limited to the limited application rate of the internal area (allowing the area to be limited to less than 30% of the internal area, flameproofing the surface and confirming the verification by related authorities) due to the fire safety problem. It is a material and exhibits design limitations in the shape in which the perforations are exposed to the surface.

Acoustic tile of U.S. Patent Application Publication No. 2000-0068792 is a porous acoustic tile made of a mixture of expanded pearlite clay starch latex cellulose fibers, which is a sound absorbing tile with a cross-sectional coupling structure. It is fragile, and the material is also vulnerable to moisture. The sound absorbing panel of Korean Utility Model Utility Model No. 20-0337820 is formed with uneven protrusion ribs by processing the inner plate material to the length and forms slit and hole that do not penetrate on the back.

The sound absorbing panel of Korean Registered Utility Model No. 20-0400107 is a sound absorbing panel that consists of a polygonal through-hole absorbing hole, which becomes narrower toward the bottom, in the form of an egg plate, and forms a sheet surface on the exposed surface. As it forms the finishing surface constituting the sheet surface, there is a lack of design limitation and surface durability as interior finishing material, and fire safety is insufficient because the manufacturing material is petrochemical resin.

In recent years, domestic construction and firefighting laws have applied higher standards in environmental and fire safety, and the fire safety standards for sound-absorbing acoustic materials have been expanded to multi-use facilities, underground spaces, assembly facilities, performance facilities, etc. Finishing materials and sound-absorbing acoustic materials are limited to the use of semi-combustible materials.

In addition, these materials have problems such as increase of manufacturing cost due to complicated manufacturing process and limitation of supply of raw materials in the case of wood materials. The artist has failed to meet the new artistic changes of the building because it presents a problem in creatively creating the interior surface finishing design characteristics.

In the case of the interior wall, it has 70 ~ 120mm of back space by installing the structural studs that make up the interior wall. Therefore, by utilizing the space already formed on the back, the sound absorbing efficiency is increased, so that low-frequency sound is absorbed at low cost. Therefore, relatively thin sound-absorbing material (absorbing paint, sound-absorbing cloth, Sound absorption tiles, thin sound absorbing boards of 5-10mm) can be used, and the design expression of the interior finish can be varied.

In general sound absorbing materials used in architectural acoustics, sound absorption of low and medium frequencies is the most important task. Therefore, in order to increase the sound absorption efficiency of low and low frequencies, a thick thickness (20-70 mm) must be maintained, which increases the manufacturing cost and design. Failure and poor durability

Therefore, in the present invention, the sound-absorbing structure of the sound absorbing structure that uses the deep empty space basically provided in the building structure as described above, and adjusts the angle of reflection and diffusion of the sound and the height of the height of the sound space In order to enhance the vibration absorbing efficiency of the plate, the plate assembly is formed in an independent structure for the purpose of improving the sound absorption efficiency of the plate, and the relatively thin sound absorbing material, sound-absorbing paint, sound-absorbing cloth, and sound-absorbing material that absorbs high frequency sound on the exposed surface of the material Tiles can be used selectively, the design expression of the interior finish can be varied, and the lighting function has been added to the resonance sound-absorbing structure molding to provide a new lighting design in the architectural interior space.

Resonance sound absorbing structure forming the molding but limiting the punched hole to the molding bottom surface (1c) to one side, the sound incident to the slit forming the bottleneck (Neck) structure proceeds to the slit bottom surface spring action in the perforated hole portion The vibration of the air is generated, such that the sound energy is converted to thermal energy is lost and absorbed. Single resonator sound absorbing material absorbs a narrow range of low frequency sounds near the resonance frequency, so if you drill a large number of holes in the bottom of the molding, you will enjoy the effect of installing multiple resonator sound absorbing devices of the single structure. As the distance from the steel wall increases, the low frequency sound absorption rate increases, and when the hole size and aperture ratio increase, the sound absorption characteristics of the porous sound absorbing material formed on the rear surface become closer. Therefore, the resonance sound-absorbing structure molding of the present invention forms a plurality of perforation holes to expand the sound absorption band, and to vary the size of the hole and the size of the hole is drilled to 2 to 12mm.

In addition, the slit constituting the neck structure (Neck) structure constituting the resonance sound absorption structure molding of the present invention acts as a deep resonance sound absorption bottleneck (Neck) structure in combination with the perforated hole to further increase the low frequency sound absorption efficiency.

As a structure for increasing the plate vibration absorption efficiency of the built-in plate, it is assembled with a resonance sound-absorbing punch molding so that the built-in plate is assembled into an independent structure [Fig. 1, 15] to form an independent structure to increase the plate vibration efficiency of the built-in plate. As a result, the sound pressure incident on the plate is converted into heat energy by the vibration of the plate, and the sound energy is converted into heat energy.

The sound absorption characteristics of the plate vibration are maximum at the resonance frequency of the low range, and the larger the rear air layer, the lower the sound absorption efficiency increases. The sound absorption characteristics are different depending on the type of plate, thickness, thickness of backing air layer, rear sound absorbing material, and installation method, and the sound absorption rate is 0.2 ~ 0.5 in the low range of about 80 ~ 300Hz. As the thickness of the plate increases, the sound absorption rate of the low range increases, and it is advantageous to fix only the edge of the plate to facilitate vibration of the plate.

Therefore, it is assembled with the perforated resonance sound-absorbing molding of the present invention to achieve an installation condition favorable to plate vibration. This condition increases the sound absorption in the low range because the space between the plate is formed and assembled into an independent structure with perforated resonance sound-absorbing molding to increase the plate vibration efficiency. In moldings 10a, 10b, and 10c forming a plurality of slit connection structures and forming a plurality of perforation holes in the bottom of the slit among the perforated resonance sound-absorbing moldings of the present invention, such molding structures are spaced between the plates. By showing the action of the spungy bridge in the space, it increases the plate vibration efficiency of the molded and assembled embedded plate, which is an advantageous installation condition to increase the sound absorption efficiency of the plate vibration.

The above-mentioned complex sound absorbing sound control structure, which makes sound absorbing and sound control of building acoustic space, expands the choice of interior interior finishing materials of building acoustic space and enables designers to express various designs arbitrarily on interior boards that make up the finishing surface. It became.

As a material that can be used as a finishing material for the interior plate, one or more materials of general paint, special paint, flame retardant paint, interior paint, flame retardant interior film, flame retardant cloth, flame retardant fabric, semi-non-flammable sound absorbing material, semi-non-flammable sound absorbing paint It is possible to creatively express the design, and suitable materials for adding sound absorbing function to the interior plate surface include semi-non-combustible spray sound absorbing material, sound-absorbing paint, sound-absorbing putty, sound absorbing cloth, and suitable construction of semi-combustible spray sound-absorbing material. The thickness is 5-15mm.

Sound-absorbing paint, sound-absorbing putty (applicant's registered patent; 0473933, published patent; 0071486) is a semi-combustible product of natural texture with a variety of interior finish expression, various spray methods, putty methods are various and simple in the field, pattern roller It is a design finishing material that creates a creative pattern by using the material. There are textile sound absorbing paint (Cotton Fabric paint, Cotton Putty), sound absorbing paint (Cotton Ball sound absorbing sound paint), and cotton ball sound absorbing sound paint has a diameter of about 2mm. Cotton balls form voids and form a continuous structure, resulting in sound absorption and diffuse reflection of incident sound. In the case of the fiber absorbing paint, the low frequency sound absorption performance is insufficient and the sound absorption characteristics of the medium and high frequency sound are about 0.15 to 0.5 at 500 to 4000Hz when the sound absorption characteristic is 3mm, so it is suitable for the front part and the middle part of the acoustic space and the thickness at the rear part. Since the construction is increased to achieve mutual coordination with the complex sound absorbing sound control structure as described above, the sound absorbing sound control structure and the resonant sound absorbing structure of the middle and low frequency sound absorbing sound zone of the molding and a variety of materials to add a sound absorbing function to the interior plate surface Complementary sound absorption function is composed, and design finishing materials with various sound absorption functions can be utilized creatively to create a new design finish of architectural acoustic space.
