In fact, many people with sensory processing disorders have trouble tuning their senses to keep the volume down to a tolerable level.

事实上，许多有感觉处理障碍的人都难以调整他们的感官以将音量降低到可以容忍的水平。

If a tolerable level of employment requires a rate of interest much below the average rates which ruled in the nineteenth century, it is most doubtful whether it can be achieved merely by manipulating the quantity of money.

如果可容忍的就业水平要求利率远低于 19 世纪占统治地位的平均利率，那么仅靠操纵货币数量能否实现这一点就很值得怀疑了。

So long as a tolerable level of employment could be attained on the average of one or two or three decades merely by assuring an adequate supply of money in terms of wage-units, even the nineteenth century could find a way.

只要仅通过确保以工资单位计的充足的货币供应，就可以在一、二或三年的平均水平上达到可容忍的就业水平，即使在 19 世纪也能找到方法。
