Pitch strength is a distinct perceptual dimension absent from loudness

Evidence

The data described here point to an aspect of pitch that is not present in the perception of loudness — sounds can also have a weak or a strong pitch. This dimension is referred to as pitch strength. Pitch strength is typically quantified using magnitude estimation techniques, in which the listener rates the pitch strength of a sound. We consider high-frequency pure tones to have low pitch strength, whereas low-frequency pure tones have a high pitch strength. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1248

Categorization

• DEFINE: Defines pitch strength as an independent perceptual dimension with a specific measurement method, contrasted explicitly against loudness.
• corroborated: 3 independent passages support this claim — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1248
• XREF: connects to: Pitch strength and loudness scale at sharply different rates with level changes.; Perceived pitch shifts measurably with loudness in frequency-dependent directions — David M.
