Hanging baffles and banners are a very
effective for acoustical treatment in large open rooms.
The acoustical baffles and banners have very high sound
absorption coefficients ranging from NRC .75 up to NRC
1.15. Acoustical baffles are designed to hang vertically
down from a ceiling, acoustical banners are designed
to be hung horizontally to a ceiling. Both are very
effective sound absorbers that work well to reduce reverberation
and increase speech intelligibility.
