Enabling and Using Sound
Sound can help make your presentations richer in a number of ways. For example, if your meeting or class can get heated and out of hand, you might use a sound to instantly grab everyone’s attention and get them to take a deep breath. You might use sound to give the pronunciations of difficult words in a language lesson. You might use sound to congratulate the person who got a right answer or contributed something useful to the discussion.
All the objects work independently of each other, enabling you to add different sounds to different objects.
