Evaluation of detailed noise and vibration measurements on a wire strander led to the identification of noise sources. The same data were used to optimize the selection of absorption materials while meeting the severe space limitations imposed by the equipment design. The acoustical treatment resulted in a 6-7 dBA noise reduction.
对绞线机进行详细的噪声和振动测量评估后，确定了噪声源。利用相同的数据在满足设备设计所带来的严格空间限制的同时，优化了吸声材料的选择。声学处理使噪声降低了6 - 7分贝。
