This can be either sound absorptive or reflective. Absorptive is
generally used in large spaces such as auditoriums or open office designs. When absorptive is
desired, fiberglass acoustical panels are one of the best mediums on the market today.
Fiberglass panels can absorb l00% of the sound striking its surface. The exposed
surface may be a fabric, perforated metal or wood, porous paint finish, acoustically
transparent coating or some other material. If a sound reflective ceiling is desired, there
are many "hard" surfaces that can be used to bounce sound such as metal,
wood, glassfiber reinforced gypsum, or others.
