关于“静音”的英语表达，以下是更高级的用法和补充说明：
一、核心表达
mute 最常用且标准的表达，指通过按钮或设置将设备声音关闭。例如：
- "I pressed the mute button on my phone so she couldn't hear the background noise."
- "Please mute the microphone during the meeting."
silence
作为名词时，表示“沉默”状态，例如：
- "The concert was so loud that we had to request silence."
- "He maintained silence for the duration of the meditation session."
二、相关表达
put on mute： 主动操作设备进入静音模式 "She put the TV on mute while watching the movie." 
set to mute：通过设置界面调整
"I set my phone to mute in airplane mode."
vibrate mode：将设备调为振动模式（非静音）
"The meeting started, so I switched my phone to vibrate mode."
三、易混淆点辨析
sound off：意为“关掉声音”（动词短语），与静音不同。例如：
"Turn off the sound to avoid disturbing others."
mute与 silence的区别：
mute是动作（关闭声音），silence是状态（无声音）。例如：
- "He muted his phone."
- "The room was in silence."
四、扩展应用
在正式场合，可使用以下表达：
"It is customary to mute electronic devices in class."
"We requested silence to focus on the presentation."
通过以上表达，既能准确传达静音意图，又能根据语境选择更贴切的用词。
