    Abstract: In some embodiments, an apparatus and a system, as well as a method and an article, may include exciting a plurality of signal source pairs having a substantially equal and non-zero acoustic signature amplitude difference in a frequency domain to provide acoustic signal data, and acquiring the acoustic signal data along a selected azimuth. The plurality of signal source pairs may comprise acoustic bender plates, perhaps included in the outer wall of a downhole tool.

    Abstract: One or more acoustic transducers are used to measure ultrasonic velocities in the mud in the interior channel of a drill collar. Corrections may be applied for temperature and/or fine grain drill cuttings to get the ultrasonic velocity in the annulus between the drill collar and the borehole wall. The latter velocity may be used for caliper measurements and for correcting measurements made by formation evaluation sensors.
