Sound-Power Flow

Sound-Power Flow: A Practitioner s Handbook for Sound Intensity Robert Hickling, Sonometrics Inc., USA A comprehensive review of topics involving Sound-Power Flow Sound-power flow (sound intensity) is a vector quantity representing the net flow of sound power in watts per square meter in the direction of sound propagation. Sound Power Flow: A Practitioner s Handbook for Sound Intensity is a practical guide to sound-power flow. It covers computational approaches, using linear rather than logarithmic units, and relates these to practical experiments. The book demonstrates both the uses and advantages of acoustical sensing. Using the fundamental cross-spectral method, the measurement of sound-power flow in air and water is computed and reviewed. Sound-power flow in solids is also computed. Applications of sound-power are discussed, including measuring the sound power of a source, locating primary sources of noise in machinery, determining and locating underwater sources of sound, forward-looking sonar for ships and boats, harbor surveillance, community noise and directional hearing. Key features: Considers applications of sound-power flow.
Covers computational approaches and relates these to practical experiments. Reviews measurement of sound-power flow in air and water. Covers computed sound-power flow in solids. Describes directional hearing of mammals and insects. This book is an essential guide to sound-power flow for practitioners and research scientists.
