Well, I present to you a novelty of the laboratory: Class A control panels.

This object serves as a building component of test chambers for suppressing external noises and a test process in real time (the test process means checking the influence of music on a person, his mood, mental state). These panels allow you to simplify, complicate, connect, rebuild test chambers even during the test process. They can also become one of the "enemies" in the test chamber (Specified in clause 8.56 in "Test protocols")
