Auditory Phantoms, Spire of

Auditory Phantoms, Spire of is the administrative and spatial body charged with the assessment of Auditory Taxation, the maintenance of the Auditory Phantasma Taxonomy, and the stewardship of auditory non-events within the Tower. The Spire is a non-designated vertical annex to Foundational Spire 12-Kappa and is permeated at all hours by Phantoms of unheard sounds. Its principal ledger, the Grand Ledger of Auditory Potential, is physically housed on Floor 413 and underpins the Spillover Theory regarding the Kappa Resonance.

Jurisdiction and Administrative Extensions

The Spire of Auditory Phantoms exercises authority through several subordinate offices. The Vestibule of Auditory Phantoms is an administrative extension of the Spire and receives primary attestations forwarded from the Spire's local annexes. The Auditory Permit Office operates under the auspices of the Spire, issuing licences for the intentional non-production of regulated sounds. Disputes over log entries within any of these offices are adjudicated in consultation with the Spire of Auditory Phantoms, as established by Seventeenth Concordance, Clause 17.404.1a, which states that "no residue shall be logged without the counter-signature of a Phantom auditor appointed by the Spire." The Spire additionally administers Auditory Cartography in matters of procedure, a role contested by the Western Spire since the 9th Cycle.

The Audit of the 14th Cycle

In the 14th Cycle the Spire ratified Concordance 47, formalising its method for the measurement of Auditory Residue. The ratification was not uncontested: the Auditory Annex of Floor 347 submitted a minority recension arguing that residue should be measured by silence-weight rather than by duration of non-occurrence. Clerk Hestram of the Third Scriptorium recorded in the margin of the ratified copy that "the Spire has counted what was never spoken and called it a surplus; the floors below dispute the arithmetic." Hestram's grievance was never resolved, and the marginal note remains part of the sealed record. The Spire's ledger supports the Spillover Theory regarding the Kappa Resonance, a position the Hum of the Depths is held by some to contradict.

"The unheard is taxable only where the Spire declares the hearing to have been omitted in error; the intentional omission is a permit, not a debt."

— Auditory Taxation, Recension 3, §12

Classification of Phantom Residents

The Spire maintains the Auditory Phantasma Taxonomy, within which Resident Phantoms are distinguished from Documentary Phantoms and Anticipatory Phantoms. Resident Phantoms are those settled permanently in a floor's acoustic absence; Documentary Phantoms arise from misfiled attestations; Anticipatory Phantoms precede a sound that is scheduled but not yet omitted. The Auditory Phase of a floor determines which class predominates, and the Spire's local annexes log primary attestations for Auditory Confirmation accordingly. A visitor to the Vestibule may not bring an instrument capable of sounding, on penalty of reassignment to the Western Spire's custody for one full Cycle.

Scholarly Disagreement on the Spillover

A longstanding dispute concerns whether the Spillover Theory recorded in the Grand Ledger of Auditory Potential is consistent with Concordance 47. The Spire holds that the Kappa Resonance spills unheard sound upward through Foundational Spire 12-Kappa, whereas the Auditory Annex of Floor 347 contends the spill is downward and was mis-entered in the 14th Cycle. The Seventeenth Concordance, Clause 17.404.1a indirectly favours the Spire's reading, but the Third Concordance Annex 4 asserts that "all resonances are local to the floor of their non-occurrence," a position incompatible with either spillover claim. No adjudication has reconciled these texts.

Physical Description and Access

The Spire of Auditory Phantoms is entered from Floor 413 via the Auditory Permit Office's antechamber, though the Spire itself extends through numerous non-sequential floors. It is permeated by Phantoms of unheard sounds, most densely near the Grand Ledger. The Spire's local annexes, including the Auditory Annex of Floor 347, log primary attestations for Auditory Confirmation and forward summaries to the Vestibule of Auditory Phantoms. Maintenance of the ledger requires the quarterly silencing of the Third Scriptorium, a task assigned to Clerk Hestram until his reassignment in the 15th Cycle.
