![]() ![]() Recent studies have revealed that audible sound stimulation has a great potential to improve plant growth and the quality of products. ![]() used audible sound waves to stimulate more than 50 different crops and achieved remarkable effects. Recently, studies have been done on the use of music to improve crop yield and quality in plants such as tomato, vegetables, and barley. Early studies have shown that some frequencies affect seed germination and the growth of plants differently than others. Little has been done with audible frequencies (20–20000 Hz) on seeds or whole plants and what has been done is mostly with single frequencies. The vast majority of these papers deal with ultrasonic (above 20000 Hz) or subsonic (below 20 Hz) frequencies studying effects at the cellular and genetic levels. There are scientific literatures related to studies on the effects of subjecting seeds and plants to sound waves or magnetic field. The study provides us with a way to understand the effects and rules of sound field on plant growth and a new way to improve the production of mung bean. Audible sound treatment can promote the growth of mung bean differently for distinct frequency and intensity. Experimental results indicated that the sound wave can reduce the germination period of mung bean and the mung bean under treatments of sound with intensity around 90 dB and frequency around 2000 Hz and significant increase in growth. The growth of mung bean was evaluated in terms of mean germination time, total length, and total fresh weight. Audible sound ranging 1000–1500 Hz, 1500–2000 Hz, and 2000–2500 Hz and intensities were used to stimulate mung bean for 72 hours. In this work, the effect of audible sound on germination and growth of mung bean ( Vigna radiate) was studied under laboratory condition. Not much effort has been put forth in studying the relation of plant and audible sound. ![]() However, the interaction between audible sound and the growth of plants is usually neglected in biophysics research. Audible sound (20–20000 Hz) widely exists in natural world. ![]()
