Provided is an anomaly notification system (100) which issues a notification of an anomaly with a caree (CR) who is in a room (R1), said system comprising: a sensor (11) which measures a quantity of activity of the caree (CR)； a sound collection unit (21) which collects a sound within the room (R1)； and a first assessment unit (31) which assesses whether the volume of the collected sound is greater than or equal to a reference volume. The anomaly notification system (100) further comprises a second assessment unit (32) which assesses whether the sound in question, the volume whereof has been assessed to be greater than or equal to the reference volume, is a prescribed activity sound that arises from the activity of the caree (CR). The anomaly notification system (100) further comprises: a third assessment unit (33) which, if it has been assessed that the sound in question is the activity sound, assesses whether an anomaly has occurred with the caree (CR) on the basis of the quantity of activity which was measured before and after the time at which the sound in question was collected； and a notification unit (24) which, if it has been assessed that an anomaly has occurred with the caree (CR), issues a notification that an anomaly has occurred with the caree (CR).L'invention concerne un système de notification d'anomalie (100) qui émet une notification d'une anomalie avec un porteur (CR) qui se trouve dans une pièce (R1), ledit système comprenant : un capteur (11) qui mesure une quantité d'activité du porteur (CR) ； une unité de collecte de son (21) qui collecte un son à l'intérieur de la pièce (R1) ； et une première unité d'évaluation (31) qui évalue si le volume du son collecté est supérieur ou égal à un volume de référence. Le système de notification d'anomalie (100) comprend en outre une deuxième unité d'évaluation (32) qui évalue si le son concerné, dont le volume a été évalué comme étant supérieur ou égal au volume de référence, est un son d'activité prescrit qu
