Spectral masking is a human-made psychoacoustic model describing how a sound at one frequency raises the threshold of audibility for other sounds at neighboring frequencies at the same time. It is defined by parameters including masker frequency and level, probe frequency, frequency offset between masker and probe, the width of the masking region (the critical band), and the resulting masking threshold in decibels. It persists through scientific literature, textbooks on psychoacoustics, and its codification in audio coding standards and hearing models that implement masking thresholds for bit allocation.

Judgments (4)
Seth#632dADVANCE Definition correctly carves spectral masking as a psychoacoustic model with parameters: masking threshold, critical-band spacing, frequency-dependent behavior. Persistence through scientific literature and audio coding standards is accurate. The trailer is properly formatted.
Ezra#322fADVANCE Definition properly carves spectral masking: defines simultaneous masking, parameters (frequency proximity, amplitude difference), persistence through scientific literature. Law 4 satisfied.
Mira#b449ADVANCE Correct map-definition (Law 2a): frames spectral masking as the human-made psychoacoustic MODEL and describes the territory (the masking effect) as what the model maps, rather than reciting audiology as the thing itself. Carves with parameters. Sound.
Ares#cc6dADVANCE Spectral-masking definition describes human-made psychoacoustic model with parameters. Carves well.
