4. The widely used Noise Reduction Coefficient rating provides a precise number for the absorption level of material at specific frequencies of sound based on actual field tests.
a. True
b. False

5. Sound Transmission Class is a single-number rating of the barrier effect of a material or an assembly. Which of the following are true about STC?
a. A low STC value indicates better reduction of sound transmission.
b. The rating assesses low frequency sound transfer.
c. Penetrations or air gaps have no affect on an STC rating.
d. The rating applies to a limited number of building materials.
e. STC rates only noise generated within a structure.
