SOUNDPROOF STRUCTURE, SOUND ABSORBING PANEL, AND SOUND ADJUSTING PANEL
There are provided a soundproof structure, which can have high soundproofing performance in a wide frequency band and in which visual recognition of through-hole can be suppressed, and a sound absorbing panel and a sound adjusting panel using the soundproof structure. A sheet member having a plurality of through-holes passing therethrough in a thickness direction and a sound absorbing body disposed in contact with one main surface of the sheet member are provided. An average opening diameter of the through-holes is 0.1 μm or more and less than 100 μm. Assuming that the average opening diameter of the through-holes is ϕ (μm) and an average opening ratio is σ a parameter A expressed by A=σ×ϕ+2 is 92 or less.
