Two cases of intractable auditory hallucination successfully treated with sound therapy

We report two cases of patients with schizoaffective disorder with treatment-refractory auditory verbal hallucinations (AVHs) who were successfully treated with sound therapy, which is effective to treat tinnitus. AVHs in both patients were alleviated within about one month, and no recurrence was reported for 31 and 17 months after the sound therapy together with medication. Further studies may confirm the therapeutic value of sound therapy in patients with intractable AVHs.
