Abstract

This study examines air, recycled plastic grains, fibers from rubber shreds and sawdust fibers as sound insulation materials to attenuate sound produced from continuous working lab fatigue test machine. These waste materials are filled in between a double glazed-aluminum framed box. The sound attenuation is tested at three studied 0.5, 1.0 and 1.5 m distances. Since the sound wave is propagated in three dimensions, the experimental work is employed in four upper, fronts, motor and sample fixture side directions. Moreover, the study is extended to examine temperature increase due to enclosing. Tests of sound level are carried out with closed and opened inlet and outlet designed slotting according to a box size. Gradual sound attenuation reaches 18, 20, 22 and 25% for air, plastic grains, rubber and sawdust fibers, respectively. The present work proves that waste materials are efficient in noise removal from sound sources. Also, they help the environment cleanliness from synthetic disposable bottles and tires as well as bio-wood wastes and assist the sustainability of earth.

采用不同类型的废材对双层玻璃箱之间的效果进行隔声疲劳试验机

本研究考察了空气、再生塑料颗粒、橡胶碎片纤维和锯末纤维作为隔声材料来衰减实验室连续工作疲劳试验机产生的声音。这些废料被填在一个双层玻璃铝框盒子之间。在0.5米、1.0米和1.5米的距离上测试了声衰减。由于声波是三维传播的，因此实验工作在上、前、电机和试样夹具侧四个方向进行。此外，研究还扩展到研究封闭引起的温度升高。声级试验采用按箱体尺寸设计的进出口开闭开槽进行。空气、塑料颗粒、橡胶和木屑纤维的逐渐声衰减分别达到18%、20%、22%和25%。本研究证明了废弃物对声源噪声的去除是有效的。此外，他们帮助环境清洁从合成一次性瓶子和轮胎以及生物木材废料，并协助地球的可持续发展。

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
