Effect of sound on plant growth

This study is an attempt to understand the effect of noise on plant growth and behavior. The common bean plant (Phaseolus vulgaris) has been subjected to two different set of sound, first, rhythmic violin music, and second, non rhythmic traffic noise for one month. A control set of plants have been exposed to no particular noise. The music is being played using normal speakers for three hours, twice each day. The parameters such as difference in height of the plant and number of leaves are all monitored on a regular basis. The results show that the plants are not able to very clearly distinguish between rhythmic and non-rhythmic noise but are definitely showing positive effects on exposure to any kind of sound.
