机器声在这儿更大了。

The machinery sounds were louder here.

他们依然能听出农场的机器声。

Their ears were still attuned to the sounds of the farm machinery.

一年中这个时候最浓烈，因为遇上假期的供应旺季，机器声轰鸣不断，这时也是巧克力生产商赚钱的最佳时节。

It is especially pungent this time of the year, when the factories are humming to meet holiday demand, the chocolate-maker's bonanza.

震耳欲聋的机器声从开敞的门处传来，一台设计巧妙的传送带和旋转器将腰果按大小分类并将他们输送至麻袋。

A deafening rattle comes from the machine by the open door, a green contraption of conveyors and rotating metal drums that sorts cashews by size and drops them into sacks.
