The use of acoustic emissions (AE) in physiological research dates back to the year 1966, when it was discovered that petioles of leaves under drought stress emit audible vibrations. The vibrations were recorded by audio sound transducers. The past couple of years have resulted in rapid developments in microelectronics leading to new advancements in the AE technique applied to plants. High performance acquisition systems are now available that can record and store waveforms from multiple channels at high sample frequencies. — Adapted from “From hydraulics to acoustics in drought-induced cavitation in plants” by Niels Baerdemaeker, PhD thesis supervised by Kathy Steppe, University of Ghent, 2018
