The sounds you want to use should be carefully selected music backgrounds. Use them as the spice of your presentation, not the main course of the meal. However, the best sound to use is the voice of satisfied customers. Couple the voice of a satisfied customer with a picture and it creates a powerful testimonial that can help you close a sale. Use video .
Video is one of the most powerful communication devices.
You can create videos of powerful messages on your computer and then play them back for audiences. A fast way to do that is with Alaris' QuickVideo Transport or Dazzle from Dazzle Multimedia. Consider a big-screen laptop . If your presentation is to a group of 10 or fewer, you might want to consider using a laptop with a 13.3-inch or larger screen. A screen of this size can be seen easily by as many as 10 people and it is more portable.
