    摘要： A double-walled damping structure includes two parallel face plates 1 and 2, a plurality of ribs 3 and 4 extending in the same direction to connect the two parallel face plates 1 and 2, wherein in a section taken perpendicularly to the direction of extension of the ribs 3 and 4, all or most of the holes defined by the adjacent two ribs and the face plates are trapezoidal. The structure less transmits vibration, and is capable of further increasing a damping effect when a damping material is attached. A double-walled sound insulation structure includes two parallel face plates 1 and 2 having a same thickness, a plurality of vertical ribs 3 extending in parallel with an equal pitch to connect the two parallel face plates 1 and 2, wherein assuming that the Young's modulus, density and thickness of each of the face plates are E, &rgr;, and t, respectively, and the pitch of the ribs is 1, the following equation (1) is satisfied: [Formula 1] 250 ≤ k 2 4 ⁢ π · t l 2 · ( E / 3 ⁢ ρ ) 1 / 2 ≤ 5000 ⁢ ⁢ (wherein ⁢   ⁢ k = 4.72 ⁢ ) ( 1 ) The structure effectively exhibits a sound insulating effect by itself, and is capable of further increasing the sound insulating effect when a damping material is attached.

    摘要： A truss type extruded aluminum section (1) is formed of a pair of planar plates (2)(3) and ribs (4)(5)(6), wherein hollow portions (7)(8)(9) are formed within the section (1) by the ribs (4)(5)(6) and the planar plates (2)(3). Vibration-damping resin is provided on the inner surfaces of hollow portions (7)(8)(9), and particularly on the inner surface of the planar plate (3) and on a single surface of the inclined rib (4). With this arrangement, the vibration energy bending the planar plate (3) and the rib (4) is converted into a heat energy. In the case of manufacturing such truss type extruded aluminum vibration-damping section (1), for making easy the insertion of the vibration-damping resin in the hollow portion, the vibration-damping resin is stuck on a plastic film (11) to form a long planar body. The plastic film (11) serves as a cover or an adhesive. Moreover, in the case of directly inserting the vibration-damping resin sheet (14), the vibration-damping resin sheet (14) is subjected to embossing on the adhesive-bonding side for allowing air to escape. Additionally, in the case using an age-hardening type aluminum alloy, the adhesive-bonding for the vibration-damping resin by heating is performed along with the heat treatment for age-hardening.

    摘要： A porous sound absorbing structure 10 includes an exterior plate 1 and a closing plate 2 in order to suppress a decrease in sound absorbing performance in a wide frequency band. An interior plate 3 is arranged between the exterior plate 1 and the closing plate 2, and air layers 4 and 5 are located between the exterior plate 1 and the interior plate 3 and between the interior plate 3 and the closing plate 2 respectively. The exterior plate 1, the interior plate 3, and the closing plate 2 are arranged while opposed to each other. Many through holes 1a and 3a are made in the exterior plate 1 and the closing plate 2 respectively. In the interior plate 3, a plate thickness t2 and a diameter φ2 and an aperture ratio β2 are set so as to generate an viscous effect in air passing through the through hole 3a. The aperture ratio β1 of the through hole 1a in the exterior plate 1 is set more than 3% and not more than 50%.
