Description:    MECHANICS OF UNDERWATER NOISE CLASS SCOPE. This specification contains requirements for a course of instruction in the mechanics of underwater noise as it relates to shipboard acoustic quieting applications. Key principles to be addressed shall include fundamental principles of noise sources, water-borne and structure-borne noise propagation, and noise control methodologies. The class will be for up to 15 students (primarily NOAA chief engineers and port engineers). REFERENCES. Mechanics of Underwater Noise, by Donald Ross. GOVERNMENT-FURNISHED MATERIALS. NOAA will provide the classroom, audio/visual (projector) and video conferencing capability. NOTE: Up to half of the 15 participants may be taking the class remotely via video conferencing and web conferencing. REQUIREMENTS. The contractor shall provide qualified instructor(s), course materials, texts (each participant shall receive a copy of the referenced text), necessary to provide participants with a basic understanding of underwater noise and ship quieting methodology. The course shall address the following topics: Fundamentals. Definitions, units, sources, spectral and temporal properties, wave equation, radiation and propagation, reflection, absorption and scattering, structure-borne noise, interaction of sound and structures. Noise Sources in Marine Applications. Rotating and reciprocating machinery, pumps and fans, gears, piping systems. Noise Models for Design and Prediction. Source-path receiver models, source characterization, structural response and vibration transmission, deterministic and statistical analyses. Noise Control. Principles of machinery quieting, vibration isolation, structural damping, structural transmission loss, acoustic absorption, acoustic mufflers. Fluid Mechanics and Flow Induced Noise. Turbulent boundary layers, wakes, vortex shedding, cavity resonance, fluid-structure interactions, propeller noise mechanisms, cavitation noise. Hull Vibration and Radiation. Flexural and membrane modes of vibration, hull structure resonances, resonance avoidance, ribbed-plates, thin shells, anti-radiation coatings, bubble screens. Sonar Self Noise and Reduction. On board and towed arrays, noise models, noise control for habitability, sonar domes. Ship/Submarine Scattering. Rigid body and elastic scattering mechanisms, target strength of structural components, false targets, methods for echo reduction, anechoic coatings. The class shall be 24 hours in length and shall be presented at the Marine Operations Center- Atlantic, 439 West York Street, Norfolk, VA between October 21 and October 23, 2008. Bid price for the class shall include travel and per diem for the instructor(s).
