Abstract
An acoustic borehole logging tool employs at least one transducer for directionally transmitting and receiving bursts of acoustic energy into the formations surrounding a borehole. The transducer is mounted in a compartment within the tool which is filled with a coupling liquid. A window in the periphery of the compartment consists of a material having a thickness which maximizes the signal-to-noise ratio of the acoustic energy for the particular wavelength of acoustic energy being transmitted.
