Because plant roots respond only to sound waves at frequencies which match waves emitted by the plants themselves, it is likely that plants can receive and transduce sound vibrations into signals to elicit behavioral modifications as a form of below ground communication.
Feb 1, 2014 · Sound waves stimulation could increase the plant plasma-membrane H +-ATPase activity, the contents of soluble sugar, soluble protein, and amylase activity of callus. Moreover, sound waves could increase the content of RNA and the level of transcription.

Oct 26, 2022 · The perception of sounds could be an evolutionarily advantageous adaptive trait for plants. A study of the literature conducted by Agroscope shows that the positive effects of sound waves on growth, development and disease resistance are well documented by numerous research findings.
Jul 1, 2023 · In addition to positive effects on plant growth and resilience, sound alerts plants of potential danger and aids in defense. Sound guides plants towards essential resources, like water, through phonotropic root growth. Sound also facilitates mutualistic interactions such as buzz pollination.
Sound vibration is one of natural stimuli trigging physiological changes in plants. Recent studies showed that sound waves stimulated production of a variety of plant secondary metabolites, including flavonoids, in order to enhance seed germination, flowering, growth or defense.
Feb 15, 2023 · Phytoacoustics is a term suggested by Khait et al. (2019) to describe sound emissions and sound detection by plants. In addition to being abundant, sound stimuli are reliable informational signals from the environment for many organisms.
Aug 1, 2022 · Exposing the plant to caterpillar chewing playback sound elicits similar response as generated during actual caterpillar chewing which suggests that plants may respond to sound alone even without physical touch or cut by insect. Exposure to 500 Hz mono frequency waves was found to elicit better defense response in Arabidopsis (Ghosh et al., 2016
