    摘要: A double wall structure capable of suppressing an increase in a sound transmission amount with regard to sound with a specified frequency and stably exhibiting a sound insulation performance for sound with various frequencies is provided.A double wall structure 1 is assumed to be a door serving as a part of an automobile. The double wall structure 1 is provided with plate-like bodies 2 and 3 arranged in parallel and opposing to each other with leaving a predetermined distance. The plate-like bodies 2 and 3 are formed in a rectangular shape with one direction being slightly longer. Between the two plate-like bodies 2 and 3 opposing to each other is formed an internal chamber 4. Side plates 5 are provided so as to connect the plate-like bodies 2 and 3 to each other, and thereby the internal chamber 4 is almost closed. At a position where a sound pressure is increased in the internal chamber 4 is provided a sound absorbing chamber structure 6 having a porous surface 6a on one surface in a rectangular parallelepiped.

    摘要: It is an object of the present invention to obtain the configuration in which sound transmission can be decreased and sound insulation property can be enhanced in a double wall structure as an automobile part such as a door, a hood, and a truck lid. In a double wall structure in which an internal space 4 is formed between facing plate-like bodies 2 and 3 and the internal space 4 is closed, at least one sound absorbing material 6 which reduces an air particle speed is provided at a position where the air particle speed is maximum in the internal space 4 or near the position. As the sound absorption material 6, a porous body, a plate-like body, a foil-like body, and a film-like body (including the material having many through holes) can be adopted. The sound absorbing material 6 is in contact with at least one of excitation-side plate-like body and radiation-side plate-like body in the facing plate-like bodies 2 and 3.

    摘要: A double-wall structure (1), comprising plate-like bodies (2) and (3) disposed oppositely to each other to form an inner room (4) therebetween, peripheral members (5) disposed so that the inner room (4) can be completely or approximately closed, and perforated plates (13) with a large number of holes (8) disposed between the plate-like bodies facing each other. The double-wall structure is characterized in that an air layer (A) is interposed between the perforated plates and the peripheral members. Thus, since the double-wall structure can suppress the deterioration of a sound reduction index for sound with specific frequencies, it can stably develop sound insulation performance for sound with the various frequencies.

    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%.
