Abstract
An object is to provide a soundproofing structure, a partition structure, a window member, and a cage which exhibit high soundproofing performance in a broad frequency band, can be miniaturized, can ensure ventilation properties, and have a light transmittance. Provided is a soundproofing structure including: a plate-like member which has a plurality of through-holes passing therethrough in a thickness direction; and a frame member which includes an opening portion, in which membrane vibration of the plate-like member is enabled by fixing the plate-like member to a peripheral edge of the opening portion of the frame member, an average opening diameter of the through-holes is in a range of 0.1 μm to 250 μm, and a first unique vibration frequency of the membrane vibration of the plate-like member is present in a range of 10 Hz to 100000 Hz.
