The document discusses codes and conventions for using tone of voice, sound effects, ambient sounds, music, tracks, and sound levels in advertisements. The tone of voice depends on the genre and is usually excited to engage buyers. Sound effects are genre-specific and louder than music but not dialogue. Ambient sounds provide context like outdoor noises. Music matches the genre to set the mood. Adverts typically have dialogue, music, and sound effect tracks, and sound levels prioritize dialogue volume.
