To investigate plants’ airborne sound emissions, Khait et al. constructed a reliable recording system, where each plant is recorded simultaneously by two microphones; first, they recorded plants within an acoustic box and developed machine learning algorithms to classify the recorded sounds; then they tested the system in a greenhouse, while monitoring physiological parameters of the recorded plants.
