I have an alias called "ding" that plays a sound. Add "; ding" to a command and you're set.

Wow, I love that. Would you mind posting the full alias?

    printf '\a'

or if you want to display a MacOS notification

    function alert {
        osascript -e 'display notification "'"$1"'"'
    }

I liked this idea so I packaged 'ding' into something you can install[1].
