警告声响起时屏幕闪烁
您的计算机将针对特定类型的消息和事件播放简单的警告声。如果您很难听到这些声音，可以在播放警告声时让整个屏幕或当前窗口闪烁。
This can also be useful if you’re in an environment where you need your computer to be silent, such as in a library. See 选择或禁用警报声音 to learn how to mute the alert sound, then enable visual alerts.
Go to the desktop and start typing Accessibility.
Click on Accessibility to open the panel.
在声音模块按下视觉警告。
Switch the Visual Alerts switch to on.
选择需要闪烁整个屏幕还是仅当前窗口。
您可以在顶部面板上的辅助功能图标中，快速启用视觉提醒。
