“In the interrogation room, silence was used as torture. But it was an invisible cruelty. No law prohibited. A few hours earlier, in the same place where Michael Ivanovich had been, Simon Berish was now locked up. Unlike the others who had passed through the room, he knew the reason why the white walls were covered with sound-absorbing material. The principle was that of an "anechoic chamber," where sounds cannot penetrate. The body compensates for the absence by creating artificial noises—tinnitus, ringing. As time passes, one becomes less and less able to distinguish reality, from the imagination.”
