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
