How to Replace Sounds with Visual Cues on Your Mac

By Mark L. Chambers

Your Mac can be customized to give those with hearing disabilities more accessibility. El Capitan can provide additional visual cues to supplement the spoken and audio alerts used throughout your Mac’s system, as well as convert stereo audio to mono (useful for folks with diminished hearing in one ear). To make use of these helpful features, simply follow these steps:

  1. Open System Preferences, click the Accessibility icon, and then click the Audio icon to display the options you see here.


  2. Select the Flash the Screen When an Alert Sound Occurs check box, and click the Test Screen Flash button to test the visual cues.
  3. To play stereo music as mono (with both channels combined as one channel from both speakers), click the Play Stereo Audio As Mono check box to select it.

To raise the overall sound volume in OS X, click the Open Sound Preferences button to display the Sound settings. With the Sound settings open, you can drag the Volume slider to the right to achieve the volume level you like.
