| 摘要 |
The invention, in its several embodiments, includes a method of making (100, 300) a plurality of impedance-matched layers (215, 220, 225) interposed between a target media (230) and an acoustical source (210), the interposed impedance-matched layers (215, 220, 225) thereby providing optimal transmission of energy from the acoustical source (210) or a transducer (110) to the target media (230). |
