Plant-acoustics is the study of acoustic signals and vibrations produced by or perceived by plants, including ultrasonic emissions and mechanical vibrations. This field is significant for plant science because it reveals how plants communicate, sense environmental stress, and respond to mechanical stimuli at a physiological level. Understanding these acoustic mechanisms provides insights into plant signaling pathways and offers potential tools for non-invasive monitoring of plant health and stress states.
