The invention concerns a sound protection screen (1) intended to be mounted under a motor vehicle, comprising a thermo-compressed shell (2) based on structural fibers bonded together by a heat-activated bonding agent, and provided with an outer face (3) covered with a protective fibrous layer (4) consisting of: between 50% and 70% of bi-component fibers comprising a high-melting point core and a lower-melting point sheath; between 30% and 50% of polypropylene fibers, so as to present an apolar component conducive to low ice adhesion, said layer having been melted at a temperature higher than the melting temperature of said sheath and polypropylene and lower than that of said core, so as to provide a smoothed surface state and to minimize mechanical ice adhesion.
