Attachment 0001 to W912EKQA016 Figure 1 Hydroacoustic Speaker Wet Test Setup.pdf

This document is a technical diagram illustrating a hydroacoustic speaker wet test setup. The figure depicts an experimental apparatus designed to test underwater speaker performance in a controlled water environment. The setup includes a water tank approximately 7 feet in width and 7 feet in water depth, containing a submerged speaker suspended at a 5-foot depth via nylon rope secured to a 2x4 wooden beam. A ladder provides access to the testing area. The control and power infrastructure consists of a laptop computer, an amplifier, a bridging transformer, and associated power distribution equipment positioned on a wooden table adjacent to the test tank. Power is transmitted to the speaker via cable connection. The speaker itself is mounted within the water tank and is designed to generate hydroacoustic output for measurement and evaluation purposes. This type of setup would typically be used for underwater acoustic testing, validation, or performance characterization of hydroacoustic equipment in a laboratory or testing facility environment.
