SOUND TEST 3 - STC Rating

The range of sound frequencies in these tests is that of human speech and hearing, and in most cases the level of attenuation achieved does not totally eliminate but rather muffles the sound to an unintelligible level. The chart show right compares the level of speech that would be heard through a door system having the indicated active (active STC rating is for an operable system as contrasted to the sealed-in-place rating of the door only).	Active STC Rating STC - 30 STC - 35 STC - 40 STC - 45 STC - 48 STC - 50	Level of Speech Loud speech understood Loud speech but not understood Loud speech audible murmur Some loud speech barely audible Hearing strained to hear loud speech Loud speech not audible
