| Foolproof means of defending against spy beams. |
| It was not a large office, but it was quite spy-proof and quite undetectably so. Spy-beams trained upon it received neither a suspicious silence nor an even more suspicious static. They received, rather, a conversation constructed at random out of a vast stock of innocuous phrases in various tone and voices. |

Compare to the cone of silence From Cease Fire (1958) by Frank Herbert, hush corner by Robert Heinlein in Double Star and the Fenton Silencer from an early Arthur C. Clarke story.
The earliest example I know of is the isolation barrage from Wandl, The Invader (1939) by Ray Cummings.
