On average, the human ear can hear sounds up to around 20kHz, while the sounds produced by plants are in the 40-80kHz region, far beyond our hearing. “The sounds made by plants can’t be heard by humans but can probably be heard by various animals, such as bats, mice and insects,” Hadany tells us. Though this has yet to be proven, it’s possible that these creatures use this information to choose which plants to eat.
A study led by Reda Hassanien of China Agricultural University in Beijing years ago, also proved that plants reacted to sound waves, with some plants greatly increasing their yield. While evidence shows that plants can react to sounds, there’s no evidence today that they can actually hear them.
32. What can we know from the six-year experiment
A. Plants of different types make the sound of the same frequency.
B. Plants produce more regular sound in certain stressful situations.
C. Plants make sounds with a much lower frequency when stressed.
D. Plants make the sound of the same frequency whatever the situation.
