Soundproof & sound partition do not mean absolute silence. Sound is spread outwards by penetration, absolute silence cannot be reached by covering a part of space. And sound source volume cannot be controlled, thus soundproof materials can only reduce intensity of sound (db), it is impossible to reach absolute silence (zero db)
