To provide an alarm sound measurement device which allows maintenance personnel to measure alarm sound at any time without actually going to an installation site of an alarming device.SOLUTION: An alarm sound measurement device 100 includes: a sound collection unit 111 installed in the vicinity of a speaker; a determination unit 113 for determining whether or not sound collected by the sound collection unit 111 is alarm sound based on both of whether or not a sound pressure of the sound exceeds a predetermined threshold and whether or not the sound is ringing sound while repeatedly changing the strength of the sound at a repetition cycle within a predetermined cycle range; a data generation unit 114 for measuring the sound pressure and the repetition cycle of sound collected by the sound collection unit 111 after the determination and generating measurement data based on the measurement result when it is determined that the sound collected by the sound collection unit 111 is alarm sound; and an output unit 116 for outputting the measurement data to a predetermined output destination.SELECTED DRAWING: Figure 8

    【課題】メンテナンス要員が警報機の設置現場に実際に足を運ばなくとも随時に警報音を測定することができる警報音測定装置を提供する。【解決手段】警報音測定装置100が、スピーカの近傍に設置された集音部111と、集音部111で集音された音が警報音であるか否かを、当該音の音圧が所定の閾値を越えたか否か、及び、当該音が所定の周期範囲内の繰返し周期で強弱を繰り返して鳴動する音になっているか否か、の両方に基づいて判断する判断部113と、集音部111で集音された音が警報音であると判断された場合、その判断後に集音部111で集音される音の音圧及び繰返し周期を測定し、その測定結果に基づいて測定データを生成するデータ生成部114と、測定データを所定の出力先に出力する出力部116と、を備えることを特徴とする。【選択図】図8
