We propose land and building plans that are suitable not only for the desired land's topography but also for the road conditions. [Solution] The method for generating land and building plans is characterized by causing a computer to perform the following processes: acquire the desired land shape in response to user operation; acquire the road frontage portion facing a road in the acquired land shape; acquire land information including at least the area of ​​the land; extract at least one building that matches the extraction conditions including the acquired land shape, the road frontage portion, and the land information from a building database that has registered buildings, building area, and floor plans in association; and output data relating to the extracted building.

The invention relates to the field of acoustic new material design, and discloses a multi-spiral-configuration acoustic metamaterial capable of being used for a sound barrier, the multi-spiral-configuration acoustic metamaterial comprises a base module and a metamaterial module, the base module is a cube with the outer surface containing a hole inserting area and a conical guide channel and the interior containing a cavity, and the metamaterial module is composed of four spiral units; and the four spiral units are correspondingly assembled in the opening insertion areas on the upper, lower, left and right surfaces of the base module respectively. The inherent contradiction between the low-frequency noise reduction performance and the size of a traditional acoustic material is broken through, the sound path allocation principle and the Helmholtz resonance theory are fused, the sound wave propagation distance is prolonged by means of a spiral structure, the sound energy loss is enhanced in combination with the resonance effect, the low-frequency-band broadband noise reduction effect is guaranteed, meanwhile, the overall structure size is greatly reduced, and the cost is reduced. Miniaturized design is achieved, and technical support is provided for miniaturization and low-cost landing of low-frequency noise reduction projects in various scenes such as bridges, tunnels and frontage buildings.
