Document Type and Number:
Japanese Patent JP2008009014
Kind Code:
A
Abstract:
To provide a porous soundproof structure which can ample sufficient sound-absorbing performance in a wide frequency band, without having to excessively enlarge the sound-absorbing structure.
The porous soundproof structure 100 is so constituted that a porous panel 2 with a large number of through-holes 2a is arranged to face a panel member 1 with a shut-off surface 1a, to intercept the air from passing therethrough, and is provided with a resonator 4, including frame bodies 4a, 4b which partition the space sandwiched between the panel member 1 and the porous panel 2, to form resonance chambers 4c, and hole parts 4d which allow the resonance chambers 4c to communicate with the outside of the resonance chambers 4c.
