Argent Silence

Definition and Classification

Argent Silence is the technical designation, under Concordance of Materials Annex 7, for the acoustic condition prevailing in chambers lined with the proprietary non-reflective alloy whose formula is held in the Argent Vaults. The term is frequently confused with the alloy itself, a confusion the Wardens of the Vaults have declined to correct on four separate occasions, most recently in the memorandum of Winter 3,109, on the grounds that "the distinction has never been of use to anyone standing inside it" (Wardens of the Vaults, Circular 44).

Argent Silence is not the absence of sound. It is the absence of echo, and the two are catalogued separately. A chamber in true Argent Silence will return a spoken word to the speaker's ear at precisely the moment the speaker expects to hear it, which is to say not at all, and the resulting sensation has been described in the survey literature as "being read one's own sentence before one has finished writing it" (Surveyor-Prime Elara Vance, Field Notes, Spiral 9).

Composition and Manufacture

The alloy is a laminate, applied in no fewer than eleven coats, each cured in darkness. The formula is held in the Argent Vaults and has never been copied in full; the Sighing Vaults hold what is generally agreed to be the ninth coat and a disputed fragment of the fourth. Calibration of finished surfaces is performed against the Argent Lantern on Floor 912, whose steady argent luminescence provides the reflectance standard by which a lining is judged either true or, in the language of the trade, "talkative."

Lining work is slow and poorly paid. A single vault of moderate size occupies a licensed crew for a season and a half, and the crews do not converse while working, since a voice raised during curing is said to enter the alloy and remain there. Whether this is true has not been established. The practice is universal.

The Vance Observations

The modern understanding of Argent Silence derives almost entirely from the observations of Surveyor-Prime Elara Vance, who first observed a flicker consistent with the cryptic moth in the Argent Vaults while conducting a reflectance survey in the winter of 3,087. Vance noted that the flicker occurred at intervals of eleven seconds and that it ceased whenever she spoke aloud. Her report, filed under Spiral 9, was initially returned by the Atrium of Judicial Silence as "insufficiently silent to be admissible," a ruling later reversed.

Vance's central claim — that Argent Silence retains a residual record of sounds made within it, recoverable by methods she did not live to specify — remains the subject of active dispute. The Chamber of Measured Silence has twice attempted recovery and twice reported nothing, which its advocates regard as confirmation and its critics regard as nothing.

Disagreement Between the Concordances

The Concordance of Materials treats Argent Silence as a property of surfaces. The Protocols of Silence, by contrast, classify it as a condition of occupancy, holding that a lined chamber is not in Argent Silence until someone has been silent in it for a full hour. The two documents have never been reconciled, and the Silence Wardens enforce whichever is nearer to hand.

"Where the lining is true and the occupant is quiet, the Silence is present. Where either fails, it is not. The question of which failure governs has been referred to the appropriate office."

A third position, advanced by Librarian-Provisional Argent in a calibration protocol now bound with the Argent Vaults survey records, holds that Argent Silence is neither surface nor occupancy but a duration, and that it can be measured only by a clock that has itself been lined. No such clock has been built. The proposal has not been withdrawn.

Incidents and Prohibitions

In the winter of 3,142 a lining crew on Floor 14,142 of the West Wing Annex completed a vault and, on leaving, discovered that the door had closed behind them and that the handle on the inner face had been omitted from the specification. They were recovered after nine hours. All four declined to describe the experience, and their debriefing transcript consists of a single line: "It was very quiet in there." The specification was amended the following spring to require an inner handle. Compliance is uneven.

Visitors to lined chambers are asked to remove their boots, not for the protection of the alloy but because the alloy amplifies the sound of a heel through the floor to a degree that has startled three separate delegations. This is stated on the door.

Under the Silence Edict, no lined chamber may be used for the conduct of a dispute, since disputants in Argent Silence tend to conclude that they have already agreed. The prohibition is widely ignored. The Petrified Silence recovered from such chambers is, by long convention, inadmissible, though the convention has been challenged twice and both challenges are pending.

Current Status

Argent Silence remains in production, chiefly for the Sighing Vaults and for the calibration chambers beneath Floor 912. The Silence Prevention office maintains a standing objection to its use in any room where a verdict is to be read, on the grounds that a verdict read in Argent Silence is heard by no one and therefore, by the office's reading of the Concordance of Materials, has not been read at all. The objection has been before the Atrium of Judicial Silence since 3,096. It is expected to be heard.
