有些宝宝听到水龙头流水的声音，无线电静电干扰的声音，自然界各种声音或白噪音的录音，甚至是吸尘器持续的嗡嗡声都会安静下来。
Some babies may also be calmed by the sound of a running faucet, a radio set on static, a recording of nature sounds or white noise—even the steady hum of the vacuum cleaner.
忙乎了整整两个小时，耳机摘掉后，才发现吸尘器压根都没插电！！
The vacuuming job took me two hours and when I took of my headset I noticed that I hadn't started the vacuum cleaner.
