Sonification of a friction sensor for an acoustic characterization of the human skin.

Résumé

RESULTS For the model based on « age », the application of the product lead to significant differences according to roughness CONCLUSIONS • The sonification of the sensor highlights perceptual differences between skin qualities • Significant effect of the application of a product on the perception of the sounds are noticed, changes that are in agreement with an increase of the hydratation and firmness, and a decrease of age • Only "extreme" differences between skin properties have been highlighted (2 classes cases) • Improvements are necessary to show more subtle differences ABSTRACT • friction properties of surfaces can be investigated via sensors that measure the signals generated during the sliding of the probe on the surface [1] • a sonification of the signals, based on the sound synthesis of a violin, was designed to make audible the differences between different skin categories (age, hydratation, firmness) • hearing tests were performed with a panel of experts, which show that noticeable differences between the sounds can be highlighted that could make possible to test the efficacy of a product and to promote it with an original musical universe. => Definition of PLSDA components Panel 1: 57 Caucasian women • 3 groups of age: 20-30 yo (N=14) , 35-45 yo (N=28), 55-65 yo (N=15) • 2 groups of hydratation: hydrated skin (N=25), dry skin (N=17) • 2 groups of skin firmness: firm skin (cutometer R7 > 0.4-N=27), looser skin (N=30) REFERENCES [1] Zahouani, H., Mezghani, S., Vargiolu, R., Hoc, T., El Mansori, M.
