Abstract

Some tire cavity noise reduction devices have been commercialized in recent years. However, the use of these devices has been limited to only some high-end vehicle models because of cost constraints. This paper describes the proposal for a new device structure that achieves a 50% or greater reduction in weight and cost over previous devices as an approach to enable general use of Helmholtz resonators that can be fitted to road wheels. And this device has been successfully applied to mass-production models on the market.
