Abstract:

This proposal addresses the need for an innovative and affordable material system that mitigates low frequency acoustic radiation through the hull induced by airborne noise in shipboard compartments containing Electronic Modular Enclosures. The proposed low frequency acoustic mitigation treatment is based on multiply-tuned, micro-sized absorbers embedded into a viscoelastic polymer matrix with a custom engineered dynamic modulus. Both, fully dense and porous polymer matrices and embedded micro-absorbs are developed and characterized in this work. The proposed acoustic treatment is a spray-on solution that can be cost-effectively apply in the field using Resodyn Corporation's portable Polymer-composite Thermal Spray (PcTS) system. Damping properties of the proposed dynamic attenuation method involving multiple tuned absorbers can be optimized to attenuate a predetermined low frequency acoustic noise band and meet all other shipboard application requirements.
