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%.

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.
