"It is change ... that is the dominant factor in society today... the world as it will be. This means that ... every man must take on a science fictional way of thinking.""

| Sound Nullifier | ||
| A barrier to sound; the cancellation of sound waves. |
| “How is it,” asked the doctor, “that in here we can’t hear the loud speaker in the anteroom, although there is no door?” “You see those ornamental spear points round the arch.” Nash stretched out a finger. “Well, diagonally between them is drawn a sound nullifying barrier. In principle, it’s not unlike those used in broadcasting except that it acts at audio frequencies. Try the experiment of putting your head through.” Obediently the doctor stepped forward through the arch. Suddenly he stiffened, shouted to Nash over his shoulder and plunged into the anteroom. Nash, hearing nothing through the sound nullifier, dawdled after him. But once in view of the antechamber, he too quickened his step. |

Compare to the Fenton Silencer from Silence Please (1957) by Arthur C. Clarke and Robert Heinlein's hush corner in Double Star in 1956. Also, see the isolation barrage from Wandl, The Invader (1939) by Ray Cummings.
