2. BEAUTIFUL DESIGN + GREAT ACOUSTICS = SOUND DESIGN

3. Acoustics play an integral role in any space. Surface finishes selected must enhance the indoor environmental quality (IEQ) of a space relative to its functionality.

4. Key factors to consider are:

5. Speech intelligibility

6. Speech privacy

7. Sound intrusion a sound perceived or understood as not belonging or inappropriate to a given sound environment, and thereby a contributor to SOUND POLLUTION.SOUND POLLUTION

9. Noise reduction ABSORPTION NCR= Noise REDUCTION COIFFECIENT HIGHER NUMBER= BETTER ABSORPTION TYPICAL ACOUSTIC CEILING= 0.70 NRC HIGH PERFORMANCE ACOUSTIC CEILING =1.00 100% ABSORPTION
