Evaluating the acoustical performance in this critical area is often attempted with a casual comparison of ratings such as NRC, STC, NIC, etc.  The NRC, set in place decades ago, is no longer held by acoustical science to be the best judge of acoustical contribution within a space.

When considering acoustical characteristics it is important to be aware that the frequencies most disruptive and distracting to the human thought process are the frequencies between 1,000 to 4,000 Hz.  For a perfect acoustic profile and the best teaching and learning environment, the lower frequencies from 16 to 500 Hz must not be absorbed.  These frequencies provide a masking effect.

As the chart above demonstrates, SilentSpace Panel offers an unmatched acoustic profile for both reflective and absorbent properties, providing a perfect acoustical profile for teaching and learning
