提供了在生物医学超声中使用的频率和强度范围内的水中的非线性声学现象。总强度，包括在介质中产生的所有谐波，用球面辐射计测量。用微型探头水听器和低通滤波器测量了波的基波分量。对理论的简单修改与观测结果非常吻合。讨论了超声的生物学效应及其在医学中的应用。
Nonlinear acoustic phenomena in water in the range of frequencies and intensities used in biomedical ultrasound are provided. Total intensities, including all harmonics generated in the medium, were measured with a spherical radiometer. The fundamental component of the waves were measured with a miniature probe hydrophone and low pass filter. Simple adaptation of the theory was in excellent agreement with the observations. The biological effects of ultrasound and applications of ultrasound in medicine are considered.
