3.1 Perceptual space

Speech perception is essentially a one-dimensional problem: intelligibility.

Music perception, on the other hand, is a multidimensional problem. Recent studies have highlighted 4 to 6 dimensions of perceptual space for musical sounds, and have sought to assign a perceptual factor to each of these dimensions. This is a very delicate task, as the perceptual factors are not independent of each other.

The proposed factors are as follows:

• loudness ;

• the envelopment effect;

• precision (clarity ) ;

• intimacy ;

• reverberance ;
