Stc rating system
WebDec 8, 2024 · For that reason, there is a rating system to help offer concrete answers as to a soundproofing material’s effectiveness. Sound Transmission Class (or STC) is a rating of sound isolation. WebAn STC rating is a single-number rating calculated in accordance with standard ASTM E413 using the Transmission Loss measured at 16 one-third octave bands from 125 Hz to 4000 Hz. This rating is most appropriate for comparing performance of interior partitions to be used between rooms where there is not strong low-frequency sound.
