Place it right at the reveal point in a quiz edit, after the question and before the score update. For a wrong answer follow it later with the windows xp error sound, and save the dj airhorn sound effect for a final round win.
About this sound
This is a sub-second bright electronic chime used as a correct-answer cue, clean and instantly recognisable. It gives listeners a quick hit of satisfaction and playful triumph, like a guess landing perfectly. It comes from Family Fortunes, the British television quiz known for survey questions and answer-board reveals.
