Abstract: Tea bushes were exposed to acoustic frequency to investigate its effect on yield and quality of tea. Frequency, volume strength and duration time of the acoustic treatment were varied to find the optimal treatment played a positive role on the tea quality and yield. Among the variables, frequency appeared to be the most critical, and the cricket chirping accompanied with symphonic music was the optimal type. Taking the economic cost and market demand into consideration, a 6-hour daily of exposure to cricket chirping at a distance within 5 to 10 m from the tea bushes could increase 12.23% on yield of tea to 24.78 g·m^-2 and 11.82% on sensory score of brewed tea to 94.6 compared to control, respectively.
