uditory hallucination occurs when people hear voices or other noises although nothing is there. As with visual hallucinations it is important to rule out possible causes such as physical illness and the side-effects of medication. It is also worth checking the person's hearing and making sure their hearing aid is working properly, if they have one. One sign that the person may be having hallucinations involving voices is when they talk to themselves and pause, as though waiting for someone else to finish what they are saying, before continuing. However, it is important to remember that not everyone who talks to themselves is having hallucinations. Shouting at people who are not there also suggests the possibility of hallucinations. People are less likely to hear imaginary sounds while they are talking to someone real so company can help. In TCM, depressed liver Qi is the main cause of auditory hallucination.
