The utility model provides a sound shielding device, which relates to the technical field of noise elimination and reduction equipment, and comprises a shielding plate and a mounting assembly, and the shielding plate comprises a shielding steel plate, a sound absorption body and glass wool. Through the arrangement of the shielding plate, the first rubber strip and the second rubber strip, the installation sealing performance and the firmness performance between the installation frame and the shielding steel plate can be effectively improved, the shaking degree of the shielding steel plate and generated noise when a railway train passes through are reduced, meanwhile, when the noise enters the sound absorption body, the sound absorption cotton absorbs the noise, and the sound absorption effect is improved. The glass wool converts noise energy into heat energy through vibration to be consumed, so that noise beside a railway is shielded, environmental noise pollution of residents around the railway is effectivel
