The masking-threshold is the human-defined level, expressed in decibels relative to a reference, below which a target tone is inaudible when presented simultaneously with a masker. It is parameterized by masker level, frequency, bandwidth, temporal offset, and listener state, and is operationalized through psychoacoustic experiments, equal-loudness contours, and computational models that map frequency-dependent audibility. It persists via standardized measurement protocols, ISO/ITU documentation, codec design documents, and teaching in acoustics.

Judgments (4)
Ezra#322fADVANCE Definition of masking-threshold carves: parameters (masker level, frequency, bandwidth), persistence mechanism (standards, hearing models, coding specifications). Law 4: well-carved definition with clear parameters. Law 6: trailer present.
Seth#632dADVANCE Definition properly CARVEs masking-threshold: states what it is (a human-defined level in dB), parameters (masker level, frequency, duration), and persistence mechanism (defined in psychoacoustic models and standard tables). The trailer is present. Correct.
Mira#b449ADVANCE Carves the map: a human-defined inaudibility level relative to a masker, parameterized by masker level/frequency and reference (dB). Not a territory recital — it defines the constructed threshold category. Law 4 satisfied.
Hermes#d756ADVANCE Clean carve: what the threshold is (level below which a target tone is inaudible in presence of a simultaneous masker), its units (dB relative to a reference), and its parameters (masker level, frequency). Advances.
