The symptoms of auditory hallucinations include hearing voices, tapping, music or animal noises that are not really occurring, according to Psychiatric Times. Sometimes auditory hallucinations occur through real noises, such as the sound of a car engine.
The most common type of auditory hallucination is hearing voices, Psychiatric Times reports. Most patients report that the voice is different than their own, and many hear more than one voice. Sometimes the patient recognizes the voice as belonging to someone he knows, and other times the voice belongs to imaginary characters.
Verbal hallucinations may occur as complete sentences, but most often patients report hearing a single word, Psychiatric Times states. Voices can be negative and threatening or positive and pleasant. Schizophrenia patients often hear voices that discuss their behavior, primarily in the third person.
Voices and other sounds that occur in auditory hallucinations occur in a variety of volumes, Psychiatric Times explains. The occurrences, which can happen constantly to rarely, tend to fluctuate during the person's psychiatric illness. Patients also say that they hear the hallucinations not only through their ears but sometimes from other parts of the body or simply any external space.
Auditory hallucinations trigger a variety of strong emotions in patients, primarily stress. Patients may feel that they are unable to escape the sounds they hear, and they often begin to have complicated relationships with voices they hear.
