Tyre design claims to halve noise

摘要

Tractor in-cab noise at high road speeds can be halved through fitting a new type of tyre to be launched this November by Continental. The company says its new Silent Speed Tyre (SST) is the world's first in this category, claiming that the design reduces noise levels experienced by the tractor driver by at least three decibels, a reduction of 50% in the decibel logarithmic scale. "There's a threshold in road speeds over which the frequency of sound produced by standard tractor rear wheel tyres starts to produce a booming or droning noise that can eventually cause long-term damage to hearing when experienced regularly over periods of time," explains Hans-Ulrich Klose, engineer with the Continental parent company CGS Tyres.
