空気吹出口等がある。 Traditionally, ducts were lined with sound absorbing material,
Alternatively, plate-shaped, cell-shaped, or other sound-absorbing materials are installed inside the duct to achieve a sound-deadening effect. However, regarding the air outlet, a punching plate or a partition wall made of an iron plate or a resin plate may be used as the air outlet. There is an air outlet, etc. in which a large number of cylindrical bodies or truncated conical cylinders are arranged concentrically as shown in FIG. 3 and a partition wall is provided.

音上の効果は期待できなかつた。(Problem to be solved by the invention) Conventionally, non-flammable sound absorbing materials have mainly been made of glass wool or rock wool, which is difficult to form into a compact form that does not easily scatter, making it difficult to apply them to air outlets. Since iron plates or resin plates are used as partition walls, air is rectified along the partition walls, but no soundproofing effect can be expected.
