Abstract

Balle de jeu pressurisée gonflée à l'aide d'un agent gazeux formé d'un mélange en proportions préfixées d'air et d'un gaz peu pénétrant qui maintient la balle sous pression beaucoup plus longtemps qu'une balle gonflée seulement à l'air. Pour réduire le bruit engendré par un tel agent gazeux, lorsqu'il entre en résonance lors d'un choc, on introduit dans la cavité de la balle une quantité suffisante d'une matière apte à perturber le mode de résonance acoustique existant dans cette cavité. Application notamment aux balles de tennis.Pressurized game ball inflated with a gaseous agent formed from a mixture of pre-set proportions of air and a low-penetrating gas which maintains the ball under pressure much longer than a ball inflated only by air. To reduce the noise generated by such a gaseous agent, when it resonates during an impact, a sufficient quantity of a material capable of disturbing the acoustic resonance mode existing in this cavity is introduced into the cavity of the bullet. . Application in particular to tennis balls.
