Abstract

Prédire comment le son se propage d'un émetteur à un récepteur n'est pas chose facile. A l'extérieur, été comme hiver, on doit effectuer des essais selon des normes qui ne tiennent presque jamais compte de la surface réfléchissante entre la source et le micro de mesure. Des données sont disponibles sur l'effet de surfaces telles que la pelouse ou l'asphalte, mais très peu ou pas en ce qui a trait aux surfaces enneigées. Cette étude aborde les aspects modélisation mathématiques et mesures expérimentales de l'effet de la neige sur la propagation sonore. Il en ressort que, sous certaines conditions, on peut prédire avec assez d'exactitude l'effet de la neige sur la transmission sonore.
