따라서 단일소재 또는 단일 차음방법 만으로는 소기의 성능을 얻을 수 없다.Therefore, a single material or a single sound insulation method alone can not achieve the desired performance.

그러나 이와같은 흡, 차음재는 중량충격음, 경량충격음, 저주파음 및 고주파음을 선택적으로 감쇄시킬 수는 있으나 주거생활에서 다양하게 발생되는 여러 형태의 소음 모두를 통합적으로 감쇄시킬 수 없는 단점이 있고, 흡습 또는 투습의 경우에는 흡,차음 효과가 급격히 저하되는 단점이 있다. However, such sound absorbing and sound insulating materials can selectively attenuate heavy impact sound, light impact sound, low frequency sound and high frequency sound. However, there are disadvantages in that they cannot collectively attenuate all the various types of noise generated in residential life.

음파는 공기를 매개로 하여 전달되는 공기전파음과 고체를 매개로 하여 전달되는 고체전파음이 있으므로 공기전파음을 감쇄하기 위하여 위와같은 홉, 차음 소재를 이용하여 흡차음시키고, 고체전파음은 복합판상의 합성고무판을 이용하여 방바닥 마감몰탈 층과 콘트리트 골조를 격리시킴으로서 방진과 제진방법으로 감쇄시키도록 한 것이다.Sound waves are airborne sound transmitted through air and solid sound transmitted through solid, so sound absorption and sound absorption is done using the above hop and sound insulation materials to attenuate airborne sound.

한편, 규조토는 규조라는 단세포 조류의 유해가 해저나 호저에 퇴적한 집합체로서 체내의 성분들이 분해하여 규산이 주체인 유각이 쌓여 지층을 형성한 일종의 화석토로서, 퇴적한 점토, 모래, 화산회, 식물질의 부식물, 수산화철, 황화철등이 혼재된 분말로 산출되는 규산질 원료이고, 규조의 유해가 퇴적한 흙덩어리이다. 그러나 지압에 눌려 굳어서 암석상태로 되어 있는 것도 있다. 순수한 규조의 유해의 화학조성은 Si0₂ 96. 16∼96.80%, AI₂0₃ + Fe₂0₃ 1.20∼1.80%, 화합수 1.92∼1.98%로서 거의 Si0₂로 되어있다. 그러나 실지로 산출되는 규조토는 규조의 유해가 바다 밑이나 호수의 밑바닥에 침적해서 생긴 것이므로, 이때 혼입된 불순물의 종류나 양에 따라서 화학적 조성도 다르고, 또 규조토에는 여러 가지 협잡물이 혼입되어 있는데 대표적인 협잡물은 유기물질, 모래 그리고 산화철이다. 유기물질은 하소하면 제거할 수 있고, 모래는 수비에 의하여 또 산화철은 소금물을 섞어서 700∼800℃에 하소함으로써 제거할 수 있다. 화석 규조의 크기는 마이크론 단위 정도이고 현미경으로 수백배로 확대하여야만 확인될 정도이고 그 구조는 원형, 반원형 등의 다공질인 세포의 집합체이다. 규조토의 물질적 성질은 규조의 종류, 모양 등에 따라 다르나 공통적인 특징은 규조의 셀(CELL)에 무수한 작은 기공이 있는 점에 있다.Diatomaceous earth, on the other hand, is a collection of fossil soils formed by the decomposition of constituents in the body by the decomposition of the components of the body, and the formation of strata. It is a siliceous raw material produced from a mixture of vaginal corrosives, iron hydroxide, iron sulfide, and the like, and is a soil mass in which harmful substances of diatom are deposited. But it is hardened by acupressure and is in a rock state. The harmful chemical composition of pure diatoms is Si0₂ 96.16∼96.80%, AI₂0₃ + Fe₂0₃ 1.20 ~ 1.80%, compounded water 1.92 ~ 1.98%, which is almost Si0₂. However, since diatomaceous earth actually produced is caused by the accumulation of the harmfulness of diatoms at the bottom of the sea or the bottom of the lake, the chemical composition is also different according to the type and amount of impurities mixed therein, and various kinds of impurities are mixed in the diatomaceous earth. Organic matter, sand and iron oxides. The organic material can be removed by calcination, and the sand can be removed by defense and the iron oxide can be removed by mixing the brine at 700 ~ 800 ℃. The size of fossil diatoms is about microns and can be confirmed only by magnification hundreds of times with a microscope. The structure is a collection of porous cells such as circular and semicircular. The material properties of diatomaceous earth vary depending on the type and shape of diatomaceous earth, but the common feature is that there are countless small pores in the cell of diatomaceous earth.
따라서, 규조토는 어떠한 천연물질 또는 인공물질보다 미세한 기공이 무수히 많기 때문에 입사음파가 기공내부에 인입되면 기공의 내원구면에 반사되어 입사음파와 반사음파가 충돌 또는 상호간섭을 일으키고, 기공의 내원구내의 공명에 의하여 높은 흡음과 차음효과가 있으며 고비중 폐철광석은 고주파음의 투과를 차단하는 효과가 있다.Therefore, since diatomaceous earth contains a lot more fine pores than any natural or artificial material, when incident sound waves are introduced into the pores, they are reflected on the inner sphere of the pores, causing incident or reflected sound waves to collide or interfere with each other. Resonance has a high sound absorption and sound insulation effect, and high specific weight waste iron ore has the effect of blocking the transmission of high frequency sound.
또한, 판형상의 합성고무판사이에 압착된 유리섬유는 어떠한 물질보다 음파의 반사율이 높고 섬유 굵기가 작은 유리 섬유로 제조되어 유리섬유시트의 두께가 얇을지라도 음파의 투과량을 크게 감소시킬 수 있다. 이는 유리섬유시트에 음파가 입사되면 유리섬유 외주면에서 반사된 반사음파가 상호 충돌 또는 간섭을 일으켜서 소음이 감쇄되는 것이며, 유리섬유시트에 라텍스(LATEX)계 접착제가 흘러들어 압착되므로 유리섬유의 비산이 방지되고 투습성과 흡습성이 방지된다.In addition, the glass fibers squeezed between the plate-shaped synthetic rubber plate is made of glass fibers with higher reflectivity of sound waves and smaller fiber thickness than any material, so that the transmission amount of sound waves can be greatly reduced even if the thickness of the glass fiber sheet is thin. This is because when the sound wave is incident on the glass fiber sheet, the reflected sound waves reflected from the outer surface of the glass fiber cause mutual collision or interference, and noise is attenuated.The latex (LATEX) -based adhesive flows into the glass fiber sheet and is compressed so that the glass fiber is scattered. Prevents moisture permeability and moisture absorption.
중량충격음파 즉, 고체에 전달된 충격음파는 격층이 많을수록 음파의 전달량이 감쇄되는데 격층사이에는 전달음을 감쇄하는 합성고무판으로 된 완충층이 형성되고 또다시 합성고무판과 합성고무판사이에는 유리섬유층이 형성되어 격층으로 적층 합지된 것이므로 전달음의 방진 및 제진효과가 향상된다.The heavy shock wave, that is, the shock wave transmitted to the solid, attenuates the amount of sound wave as the more layers are formed, and a buffer layer made of a synthetic rubber plate is formed between the layers, and a glass fiber layer is formed between the synthetic rubber plate and the synthetic rubber plate. Since it is laminated and laminated in the other layers, the vibration and vibration damping effect of the transmission sound is improved.
한편, 상기 합성고무판에는 테트라크로로프탈산무수물, 테트라브로모프탈산무수물등의 난연원료를 소정비율로 혼합하여 난연성을 높일 수 있고, 상기 합성고무판을 바닥재료로 사용할 경우에는 미끄럼을 방지하기 위하여 상기 합성고무판의 상면에 바둑판형 요철부를 형성할 수 있으며, 낮은 수준의 홉, 차음효과만을 필요로 할 경우에는 상기 판형상의 합성고무판 만으로도 사용할 수 있다.On the other hand, the synthetic rubber plate can be mixed with flame retardant materials such as tetrachlorophthalic anhydride, tetrabromophthalic anhydride in a predetermined ratio to increase the flame retardancy, when the synthetic rubber plate is used as a flooring material to prevent slipping It is possible to form a checkerboard irregularities on the upper surface of the rubber plate, and when only a low level of hop and sound insulation effect is required, the plate-shaped synthetic rubber plate may be used only.
