Results
Exposure to the forest sound resulted in the following significant differences compared with exposure to city sound: decreased oxy-Hb concentrations in the right prefrontal cortex; decreased LF/HF(sympathetic nervous activity); decreased heart rate; improved feelings described as "comfortable," "relaxed," and "natural" and improved mood states. The findings of this study demonstrated that forest-derived auditory stimulation induced physiological and psychological relaxation effects.
