SOUNDPROOFING STRUCTURE
A soundproof structure includes two or more different kinds of resonant type sound absorbing cells, and an opening part. The opening part is disposed in a position in contact with both two resonant type sound absorbing cells of the two or more different kinds of resonant type sound absorbing cells,...

| description | A soundproof structure includes two or more different kinds of resonant type sound absorbing cells, and an opening part. The opening part is disposed in a position in contact with both two resonant type sound absorbing cells of the two or more different kinds of resonant type sound absorbing cells, or the two resonant type sound absorbing cells are adjacent to each other, and the opening part is disposed in a position adjacent to at least one of the two resonant type sound absorbing cells. Resonance frequencies of one kind of first resonant type sound absorbing cells and resonance frequencies of the other kind of second resonant type sound absorbing cells different from the first resonant type sound absorbing cells match each other. As a result, this soundproof structure can achieve an absorbance of more than 50%, preferably, close to 100% even in a compact, light, and thin structure which is much smaller than a wavelength, and can achieve air permeability, heat conductivity, and a high soundproofing effect by providing a passage of air. |
