You are very perceptive and that would have been great if the original wall construction were different. In which case the absorber panels are usually not continuous. Those panels are an S-65 BA composite (meaning they are both a barrier and an absorber) perforated metal panel attached to the wall and ceiling. They requie a base and header track or channel. The acoustical doors and windows are ArtSeal 55 (they metered out at 58) They look great and are easy to clean and or change out.
