Yes, black fiberglass tissue can be used for acoustic insulation. It is a popular material in construction and home improvement due to its ability to absorb sound waves, reducing noise transmission. The fibers in the tissue create a porous structure that traps sound energy, converting it into heat and diminishing its intensity. This makes it effective in soundproofing walls, ceilings, and floors, particularly in areas where noise reduction is crucial, such as recording studios, theaters, or noisy industrial environments. However, it's important to handle fiberglass with care due to its potential health risks, and to ensure proper installation to maximize its acoustic insulation properties.
