PROBLEM TO BE SOLVED: To present information that indicates a section in which a noise generation source exists and a propagation state of the noise to surroundings.SOLUTION: A noise management device 2 comprises: a noise information acquisition unit 11 for acquiring noise information that includes the feature of noise detected in each section of a building constituted from two or more sections and a noise level that indicates the magnitude of noise; a noise section determination unit 12 for determining, when a noise whose feature matches is detected in two or more sections on the basis of the noise information acquired by the noise information acquisition unit 11, that a section where a noise of maximum noise level among noises whose features match is detected, is a noise source section, and that sections other than the noise source section among sections where noises whose features match are detected, are noise destination sections that are destinations of noise propagation; a noise propagation information generation unit 15 for generating noise propagation information that includes the noise source section determined by the noise section determination unit 12 and noise levels in noise destination sections; and an output unit 32 for outputting the noise propagation information generated by the noise propagation information generation unit 15.SELECTED DRAWING: Figure 2 【課題】騒音の発生源の存在する区画及びその騒音の周囲への伝搬状況を示す情報を提示する。【解決手段】騒音管理装置２は、２以上の区画から構成される建屋の各区画で検出された騒音の特徴と騒音の大きさを示す騒音レベルとを含む騒音情報を取得する騒音情報取得部１１と、騒音情報取得部１１が取得した騒音情報に基づき騒音の特徴が一致する騒音が２以上の区画で検出された場合に特徴が一致する騒音の中で最大の騒音レベルの騒音が検出された区画を騒音の発生源が存在する騒音源区画と判定し騒音の特徴が一致する騒音が検出された区画のうち騒音源区画以外の区画を騒音の伝搬先である騒音先区画と判定する騒音区画判定部１２と、騒音区画判定部１２が判定した騒音源区画と騒音先区画での騒音レベルとを含む騒音伝搬情報を生成する騒音伝搬情報生成部１５と、騒音伝搬情報生成部１５が生成した騒音伝搬情報を出力する出力部３２とを備える。【選択図】図２
