The device can convert sounds of around 100 decibels -the equivalent of noisy traffic, a passing train or a nearby lawnmower -into a mild electrical current.

这种装置能将100分贝左右的声音转换成轻微的电流，100分贝相当于嘈杂的车流、一辆疾驰的火车或者附近剪草机工作时发出的噪音。

For signal conditioning hardware to condition a signal, or for the DAQ device to measure it directly, you must first convert it to an electrical signal such as voltage or current.

对于信号调节、信号硬件调理或是DAQ设备直接测量，你首先必须将其换算成电信号，如电压或电流。
