Studies on the sound characteristics of phylodendron performed by measuring

the power of plant leaves with a laser beam found that the leaves of

phylodendron could produce sound waves at relatively low frequencies (from 50

Hz to 120 Hz). Furthermore, it was found that those leaves could accept

external sound wave stimulations, with frequencies lower than 150 Hz giving

the strongest responses. When the plants were under stress, such as drought,

the sound emissions from the plant's leaves increased approximately 20-30 dB,

while the range of response to external sound wave stimulation decreased

10-20 dB. However, these increased emissions returned to normal six minutes

after watering. When the stainless steel needles were inserted into the

petiole of the plant, spontaneous sound production was increased about 40 dB

for the main vein and 6 dB for the mesophyll. This is our third report on

experimental evidence that plants might have a meridian system as in humans

and other animals.
