The objectives of this project are:  to relate noise production to gas          dispersion phenomena occurring in agitated tanks; to investigate to             what extent the interaction between the sparge ring and impeller                controls bubble size; and to develop a non-visual characterization              method for the assessment of gas dispersion in chemical engineering             processes.  The work is based upon classical sound analysis techniques,         coherence studies, and acoustic intensity measurements.  The three              major regions of interest include the impeller region, the bulk of the          tank, and the sparge ring area.  The investigations identify the                various sound sources in gas dispersion and their paths to receivers,           determine the noise characteristics in frequency and space of the               various gas dispersion phenomena occurring in the tank, and rank the            various sound sources as to their importance to receivers.  The                 equipment consists of hydrophones, hydrophone calibrator, and power             amplifier.
