WebFor example, if the STC is 5 dB higher than ASTC for a given wall construction, three times as much sound power is transmitted through the ASTC wall than through the STC wall. A 10-dB difference translates to 10 times as much sound power, and a 15-dB difference is 31 times as much sound power transmitted. WebWhat is STC? Technically speaking, STC stands for Sound Transmission Class, which is the measurement used to calculate the effectiveness of soundproofing materials in reducing sound transmission between …
