Sound effects

Sound Effects helps Class 9 students understand how audio can support documents, presentations, and other Office Tools projects in Computer Applications. They learn the purpose of sound effects, how to insert or attach suitable audio, manage basic playback settings, and use sound responsibly so it improves communication rather than distracting the audience. The topic also encourages thoughtful choices about relevance, volume, timing, and file use when creating clear and engaging digital work.
