Various Sound Frequencies at Which Plants Might React
Horizontal colored bars indicate the frequency range produced by the organism or phenomenon depicted beside it. Vertical bars shaded in light green indicate that plants are able to respond to this frequency. It should be noted that plants emit sound (through cavitation) of both low (50–120 Hz) and high (20–300 kHz)
