Stimulation effect of sound waves on alfalfa (M. sativa subsp. sativa) and lentils (Lens culinaris) – a study on the effects of acoustic instruments and sine waves in the growth settings of alfalfa and lentils (English)
Abstract [en]

This research was conducted in order to provide information about the effect of sound waves in the growth settings of alfalfa (also known as lucerne) and lentils. Humans have researched about the effect of sound on humans and other animals since the beginning of our time. One of humanity’s oldest research on effects of sound is human communication. In order to expand the research of the effect of sound, this thesis expands to the area of plants. The method used consisted of playing Korobeiniki – also known as the theme song from Tetris – recorded in two versions. One version was played in piano and the second version was played in sine waves, to compare the two different frequency spectrums’ effect on plant growth. Test groups were based on the version that was played; the first group was exposed to piano while the second one was exposed to sine waves. One control group without music was used as well. Among two test groups and one control group, alfalfa and lentils grew in three batches in each group. With each batch having a unique result, the research resulted in a non-generalisable fashion, which suggests further research is vital in order to provide a conclusion which is based on more of a quantitative outcome.
