Any successful application of ultrasonics must be related in a practical way to some acoustic property or properties of the media being irradiated ulstrasonically. Evaluating the practicality of new ideas, this book includes data and functions gathered from several areas of science and technology for the purpose of facilitating the use if ultrasonic energy. It makes available data important for the design of ultrasonic systems that meet the needs of present and new developments, including applications in both standard and harsh environments. The author provides a quick reference to pertinent regulations dealing with solvents, allowable exposure levels of intensity and time, and electromagnetic limitations.
