Abstract[English]
Methods and apparatus for lowering an actual and perceived-sound level produced by sports equipment are described. In some examples, methods and apparatus to lower sound levels produced by pickleball balls are described. In some examples, internal surface features such as ribs, peaks, tabs, channels, divots and damping layers may be applied. In some examples, composite layered designs may result in lowered amplitude and/or in shifted resonant frequencies. In some examples, heat or light sources may be used to alter the internal surfaces of ball constructs. In some examples the composite layered design may include isolated surface plates. In some examples, electroactive components may reduce sound emission. Methods of measuring a sound level at frequencies and using the measurement results to iteratively design ball designs are described.[French]
L'invention concerne des procédés et un appareil pour abaisser un niveau sonore réel et perçu produit par un équipement de sport. Dans certains exemples, l'invention concerne des procédés et un appareil pour abaisser les niveaux sonores produits par des balles de pickleball. Dans certains exemples, des caractéristiques de surface interne telles que des nervures, des pics, des languettes, des canaux, des creux et des couches d'amortissement peuvent être appliquées. Dans certains exemples, des conceptions en couches composites peuvent conduire à une amplitude abaissée et/ou à des fréquences de résonance décalées. Dans certains exemples, des sources de chaleur ou de lumière peuvent être utilisées pour modifier les surfaces internes de constructions de balles. Dans certains exemples, la conception en couches composites peut comprendre des plaques de surface isolées. Dans certains exemples, des composants électroactifs peuvent réduire l'émission sonore. L'invention concerne des procédés de mesure d'un niveau sonore à des fréquences et d'utilisation des résultats de mesure pour concevoir de manière itérative des conceptions de balles.
