Abstract: The excessive use of pesticides and fertilizers reduces the quality of crops, harms human health, and causes environmental pollution, thus hindering the sustainable development of agriculture. In the process of realizing ecological agricultural production, audio control technology has increasingly become an area of concern. As a physical agricultural technology, it has become a combination of music acoustics and agricultural science. However, the research on the ecological role and function of audio control technology is still relatively lacking. In view of this, the authors studied the effects of audio control technology (specific frequency sound wave and different types of music) on the growth of lettuce, and showed that the specific frequency sound wave treatment produced by the plant acoustic frequency technology generator significantly increased the growth of lettuce compared with the condition of silent environment processing. Treatments of different types of music (electronic music, rock music, and classical music) promoted lettuce growth, especially the significant increase in the output of edible parts under the influence of electronic music. The research results further showed that the specific frequency sound wave treatment produced by the plant acoustic frequency technology generator enhanced the chlorophyll content of lettuce leaves (1.98 ± 0.15 mg/g), thus promoting photosynthesis. Different types of music had different effects on the photosynthesis of lettuce leaves; electronic music treatment increased the chlorophyll content of lettuce (1.48 ± 0.07 mg/g), and had the greatest impact.
