Figure 3. Component Correlations with Acoustic Measures.

(A) Cochleograms of the four sounds producing the highest and lowest response in each component. Cochleograms plot an estimate of cochlear response magnitudes for a sound as a function of time and frequency.

(B) Correlation of component response profiles with energy in different frequency bands. Correlation coefficients were noise-corrected (see Supplemental Methods).

(C) Correlation of component response profiles with spectrotemporal modulation energy in the cochleograms for each sound.

(D) Total amount of component response variation explained by (1) all acoustic measures (2) all category labels, and (3) the combination of acoustic measures and category labels. For Components 1-4, category labels explained little additional variance beyond that explained by acoustic features. For Components 5 and 6, category labels explained most of the response variance, and acoustic features accounted for little additional variance.

(E) Breakdown of the component response variation explained by subsets of the acoustic measures.

Error bars in all panels plot standard errors across the sound set (via bootstrap).
