摘要

Improved sonar baffles and backings are dislosed. The sonar baffles and backings comprise a porous polymer.The baffles and backings can be produced by partial selective sintering of a polyamide powder. Baffles and backings in accordance with the present invention exhibit advantageous acoustic properties, and can be manufactured to complex geometric specifications without difficulty.
