Abstract
In a multiple choice auditory experimental task, listeners had to
discriminate walks over floors made of concrete, wood, gravel,
or dried twigs. Sound stimuli were obtained by mixing temporal
and spectral signal components, resulting in hybrid formulations
of such materials. In this way we analyzed the saliency of the
corresponding cues of time and frequency in the recognition of a
specific floor. Results show that listeners differently weigh such
cues during recognition, however this tendency is not polarized
enough to enable interaction designers to reduce the functionality
of a walking sound synthesizer to simple operations made on the
temporal or spectral domain depending on the simulated material.
