Operating system sounds are audio cues produced by a computer's operating system to provide feedback to users. These sounds can indicate various actions, such as notifications for new messages, alerts for errors, or confirmation of completed tasks. Common examples include the Windows startup sound or the notification chime in macOS. These sounds enhance user experience by making interactions more intuitive. They help users recognize events without needing to look at the screen, improving accessibility. Users can often customize these sounds or mute them according to their preferences, allowing for a more personalized computing environment.
