A mathematical model is proposed to describe the isothermal germination rate of seeds as a function of time. All environmental parameters were held constant with the exception of the sound-pressure level and the frequency of the impinging sound waves. Each single frequency sound has its own set of mathematical parameters that describe the differential germination rate as a function of time. Frequencies of 100, 1000, 2000, 4000, and 9000 hertz as well as broad band noise, all at 100 decibels, were used in the experiments.
提出了一个数学模型来描述种子的等温发芽率随时间的变化。除了声压级和入射声波的频率外,所有环境参数均保持不变。每个单一频率的声音都有其自己的一组数学参数,用于描述作为时间函数的差异发芽率。实验中使用了100、1000、2000、4000和9000赫兹的频率以及均为100分贝的宽带噪声。
