These materials are called phonic insulation products.

Transparent materials allow light to pass through, Opaque objects completely stop the passage of light, Reflecting surfaces will reflect the light, and translucent objects allow the light to pass, but in a diffuse manner.
Metallic surfaces like polished aluminum or silver are highly effective at reflecting sunlight due to their high reflectivity. These materials have smooth surfaces that bounce sunlight off without absorbing much of it. Conversely, materials like asphalt or concrete absorb sunlight, making them poor at reflecting it.

A mute is used to dampen the sound. Different mutes dampen different amounts but they do not stop the sound. Vibrato is used to vibrate the sounds
