He found that the length of time it takes a sound's echo to decay is determined by the absorption of the sound's original energy by surrounding material.

他发现，声音回声衰减的时间长短取决于周围物质对声音原始能量的吸收。

During the process, ping can monitor the time it takes to send and receive the response, which can be an effective method of measuring the response time of the echo process.

在这个过程中，ping可以监视发送数据包和接收响应花费的时间，这是测量echo过程的响应时间的有效方法。
