The sound velocity in water has been measured at ultrasonic and hypersonic frequencies and the results show a negative dispersion in the supercooled region. We present measurements of sound velocity and absorption obtained by Brillouin light scattering which show that the effect of structural relaxation is not observed at 0 °C and frequencies smaller than 7.2 GHz. A correction of the hypersonic data shows that there is no apparent disagreement between the ultrasonic and the hypersonic data.La vitesse du son dans l'eau a été mesurée aux fréquences ultrasonores et hypersonores et les résultats mettent en évidence une dispersion négative dans la région de surfusion. Nous présentons des mesures de vitesse du son et d'absorption obtenues par dif...
