Abstract: A medical tool is described for supporting an individual suffering from a mental condition or disorder characterized by auditory psychosis symptoms. The tool can assist in training the individual to distinguish between an acute auditory psychosis episode and ambient sounds. The tool can monitor for a non-audio input by a patient, where the input represents an indication that the patient is hearing sounds potentially symptomatic of psychosis. A microphone can monitor ambient sounds, which are tested against a threshold to determine and whether an auditory psychosis episode may be occurring.
