To provide an abnormal sound detection system, an abnormal sound detection method, and an elevator system capable of improving accuracy of identifying a generation position of abnormal sound.SOLUTION: An abnormal sound investigation system includes at least two hoistway-inside microphone devices installed at different height in a hoistway of an elevator to collect sound data inside the hoistway and a car-side microphone device installed on a car of the elevator to collect sound data generated during the vertical movement of the car. The abnormal sound investigation system further includes an abnormal sound generation position detecting unit comparing sound data collected by the ca-side microphone device with each piece of sound data collected by the at least two hoistway-inside microphone devices and detecting an abnormal sound generation position.SELECTED DRAWING: Figure 1

    【課題】異常音の発生位置の特定精度の向上を図ることができる異常音検知システム、異常音検知方法、及び、エレベーターシステムを提供する。【解決手段】エレベーターの昇降路内の異なる高さに設置され、昇降路内の音データを収集する少なくとも2つの昇降路内マイク装置と、エレベーターの乗りかごに設置され、乗りかごが昇降動作する際の音データを収集するかご側マイク装置とを備える。また、かご側マイク装置で収集された音データと、少なくとも2つの昇降路内マイク装置で収集されたそれぞれの音データとを比較し、異常音発生位置を検出する異常音発生位置検出部を備える。【選択図】図1
