可知,本文主要讲的是现在,研究人员在《ACS可持续化学与工程》杂志上报告称,他们从海藻中提取了一种可生物降解的薄膜,可以有效地吸收这一范围内的声音,D选项“An Eco-friendly Sound-absorbing Material from Seaweed(一种来自海藻的环保吸音材料)”最符合文章标题。故选D。 反馈 收藏 ...
根据第一段中“But most of the sound-absorbing materials that can cancel out human voices, traffic noise and music are made from plastic foams (泡沫) that aren’t easily recycled or degraded.(但大多数能消除人声、交通噪音和音乐的吸音材料都是由不易回收或降解的泡沫塑料制成的)”可知,泡沫塑料的...

To combat this challenge, Volvo Car Group's acoustic lab was used. A 2500 square metre concrete chamber where the silence is so oppressive that it is almost audible. Sound-absorbing wedges coating the walls and ceiling are designed to dampen reflecting sound. The lab is entirely insulated from...
incorporating native plant species, landscapers can create sustainable ecosystems that require less maintenance and water, reducing the overall ecological footprint of a project. Furthermore, well-designed landscapes can serve as effective noise buffers, reducing sound pollution in urban and suburban ...
Soft, thick padding may sound the most comfortable at face value. But during prolonged sitting, softer padding increases pressure on the sit bones and delicate nerves rather than distributing body weight more evenly. This can create pressure points and reduce the power riders can derive from the ...
