Résumé.- Les distributions de vitesse dans le temps et dans l'espace le long de tuyaux de 7.62 cm et 2.54 cm de diamètre et d'une longueur de 64 m produites par des ondes nonlinéaires de pression d'intensités différentes ont été mesurées et comparées avec les résultats théoriques unidimension-nels obtenus par la méthode des caractéristiques avec ou sans le terme de diffusion dans le but de déterminer les caractéristiques d'atténuation de l'onde de propagation. Les données ont été ana-lysées afin d 'établ i r la relat ion entre le rapport de f lux d'énergie et la distance dans le tuyau exprimée en fonction du coefficient d'atténuation a et de la d i f f u s i b i l i t é. On a montré que ces parètres c...
