SMD is involved in the product development and supply of Acoustic Meta Materials(AMM). AMM’s are a special class of designable materials that have properties not available in natural materials.
An externally-mounted pipe sensor system is being developed based on a flexible piezoelectric polyvinylidene flouride (PVDF) wire transducer wrapped around pipe walls to measure fluidborne acoustic signatures at frequencies below 3 kHz to improve monitoring and controlling unwanted acoustic signature.
An active quiet pillow is being developed using a combination of active control and passive treatment elements in a pillow arrangement that effectively cancels and dampens harmful low, mid and high frequency helicopter tones at a patient’s ears during MEDEVAC and CASEVAC evacuation operations.
