Abstract
The purpose of my research is to see if plants perceive sounds and change their respiratory volume.
Sound has various effects, such as stimulating people to increase their concentration, but some reports
have claimed that it might also affect plants besides humans. In 1968, Dorothy Ria Lak reported that
classical and rock music influence plant growth. According to a research report conducted by Nihon
University on the theme of "the effect of sound on plants," changes in glucose metabolism of plants
were affected by sound, but details of respiratory volume were not reported. So, I wanted to find out if
there was a relationship between breathing volume and sound. The experimental method is to cover the
plant with cardboard to darken it and induce breathing. After waiting for a certain period of time, let
the plant perceive the sound frequency and measure whether there is a change in the amount of carbon
dioxide using an air quality monitor. If this experiment is successful, we can see that sound changes the
respiration rate of plants. Based on the above, my research theme is the change in plant respiratory
volume due to sound.
