Honda develops sound cancelling resonators reducing tire noise
Noise-reducing wheel resonators are made from lightweight resin, and through a unique, well considered structure, are fitted to the wheel rim without the use of connecting parts such as bolts. Centrifugal force actually secures the resonators to the wheel more firmly. The resonators can withstand 1,500G during high-speed driving, and bond to the wheel stronger without losing their shape

Sumitomo Rubber develops new technique for predicting tire noise
Sumitomo Rubber Industries, Ltd. has announced the development of a new technique for predicting noise resulting from the combined vibration of tires and vehicles. Employing a tire rolling motion simulation, the method allows both tire and vehicle manufacturers to reduce product-generated noise. This reduction enhances passenger comfort and shortens delivery time by minimizing development hours and physical prototypes. The company plans to address various user needs, including model-based tire and vehicle development, while promoting environmentally friendly tire solutions.
