FIG. 2.

Correlations between the acoustical dissimilarities calculated on the right and left channels of the recordings, for the three musical excerpts (McCoy Tyner, Kan’nida, Vivaldi): (a) time signal; (b) spectrum; (c) time-frequency transform; (d) modulus of spectrum; (e) modulus of time-frequency transform; (f) power spectral density (PSD); (g) weighted PSD; (h) 70 phone contour weighted PSD; (i) overall specific loudness; (j) time-varying specific loudness 1; (k) temporal mean of time-varying specific loudness 1; (l) time-varying specific loudness 2; and (m) temporal mean of time-varying specific loudness 2. The significant correlation coefficients are in bold, marked with an asterisk.

Mean perceptual dissimilarities with standard errors measured for the 66 pairs of recordings and the three musical excerpts (McCoy Tyner, Kan’nida, Vivaldi).

Correlations between the mean perceptual dissimilarities resulting from the listening tests and the acoustical dissimilarities calculated on the right and left channels of the recordings, for the three musical excerpts (McCoy Tyner, Kan’nida, Vivaldi): (a) time signal; (b) spectrum; (c) time-frequency transform; (d) modulus of spectrum; (e) modulus of time-frequency transform; (f) power spectral density (PSD); (g) weighted PSD; (h) 70 phone contour weighted PSD; (i) overall specific loudness; (j) time-varying specific loudness 1; (k) temporal mean of time-varying specific loudness 1; (l) time-varying specific loudness 2; and (m) temporal mean of time-varying specific loudness 2. The significant correlation coefficients are marked with an asterisk.

Tables

TABLE I.

Definition of the acoustical dissimilarities (: arithmetic mean over time , frequency , or Bark scale , : modulus of a complex value, : minimum value, : maximum value, DFT: discrete Fourier transform, STFT: short-time Fourier transform, PSD: power spectral density, : weighted power spectral density, : overall specific loudness, Dens: time-varying specific loudness, : temporal mean of time-varying specific loudness).

TABLE II.

Reverberation time (RT) measured by third-octave bands in the listening room used for the recordings, as a function of the central frequency of the third-octave band.
