About effect
The coating of Guyna is composed of multiple layers of spheres containing air in a high-density (material density: 5) special ceramic. Sound is reflected by this special ceramic and has a structure that repeats attenuation with air. In addition, the sound that has entered the inside of the coating due to the effect of the special ceramic layer that is multi-layered inside the coating reduces the vibration and reduces the sound.
