ABSTRACT:
A noise-shielding panel comprises a flat section spacedly disposed from the surface of an engine body and formed of a fibrous composite, and a contacting section integral with the flat section and formed of the same fibrous composite as in the flat section. The contacting section is in direct contact with the engine body surface and lower in density of the fibrous composite than the flat section, thereby facilitating production thereof and exhibiting a high noise-shielding effect.
