We evaluated the effect of stress-less and comfortable acoustic information on the prefrontal cortex (PFC) activity. We measured the blood flow and hemoglobin concentration changes by Near Infrared Spectroscopy (NIRS) during listening to acoustic information. We observed that right and center PFC activity increases against unpleasant acoustic information. Left and center PFC decreases for user's favorite and stress-less acoustic information. These results suggest that comfortable and stress-less acoustic information are discriminated by this observation method of asymmetric activities in PFC. The method can be applied to find stress-less acoustic resources and their stress-less and comfortable combinations
