RAL-TL06-199 The acoustical tests were conducted in accordance with the following: ASTM E 90-09 Standard Test Method for Laboratory Measurement of Airborne Due to the definition of the rating, STC is only applicable to air-borne sound, and is a poor guideline for construction that allows impact noise to pass through the structure. Smaller negatives are better than larger negative insulated laminated STC 38 glass, and a rating of 45 when using double laminated STC 45 glass. We've learned that a high STC-rated wall may suffer terribly in the low frequencies and is therefore not a true solution. 48 ROCKWOOL AFB In general, a higher STC rating blocks more noise from transmitting through a partition.
