| description | To provide a means capable of further improving the sound-reflecting performance in a frequency range of 1500 to 2500 Hz.A sound-reflecting material including a sheet having elasticity, and a support portion partitioning the sheet into a partition portion while supporting the sheet is configured so that a surface rigidity (k) of the sheet and a surface density (m) of the sheet in the partition portion satisfy a relationship of the following Expression 1. Further, the sound-reflecting material is disposed on a substrate so that the sheet is separated from the substrate to configure a sound-reflecting structure: 12πkm>900Hz |
