Study on Design Optimization of a Planar Multi-layer Structurefor Noise Reduction of Underwater Acoustic Sensors

2013 The Journal of the Acoustical Society of Korea  
In this paper, the optimization has been performed to design a multi-layer structure that is used as a structure for noise reduction of acoustic sonar sensors in underwater vehicles. Two design goals are considered to reduce self-noise from own machineries and to enhance acoustic signals detected from outside. Both distinct and continuous design parameters have been used such as selection of material properties of each layer and thickness of each layer, respectively. The sensitivity of design
