The invention relates to a through-all sound insulation structure and a mounting method thereof. The through-wall sound insulation structure comprises an embedded pipe. The embedded pipe is embedded in a wall. One end of the embedded pipe is provided with a flange. The flange is provided with a plurality of threaded holes. A sound absorption plug is mounted at the end, provided with the flange, of the embedded pipe. The sound absorption plug is in a circular pipe shape. The outer diameter of the sound absorption plug is matched with the inner diameter of the embedded pipe. Sound absorption cotton felt is wrapped outside the sound absorption plug. The sound absorption plug is filled with high-performance sound absorption cotton. One end of the sound absorption plug is provided with a sound absorption plug cover plate. The outer diameter of the sound absorption plug cover plate is provided with a sound absorption flange. The sound absorption flange is matched with the flange and provided with through holes corresponding to the threaded holes. The other end of the embedded pipe is provided with a sound insulation plug. The sound insulation plug is in a circular pipe shape. The outer diameter of the sound insulation plug is matched with the inner diameter of the embedded pipe. Sound absorption cotton felt is wrapped outside the outer surface of the sound insulation plug. The sound insulation plug is filled with high-performance sound absorption cotton. The end of the sound insulation plug is provided with a sound insulation plug cover plate. The outer diameter of the sound insulation plug cover plate is larger than that of the embedded pipe. By means of the through-all sound insulation structure, it can be guaranteed that the performance of an internal anechoic chamber is not affected when wire threading or equipment access is not needed.
