Use volume for power in your presentations

Make sure you vary the volume of your presentation as well as the pitch and pace.
It is possible to speak softly and project.
Like the “power pause”, this is another powerful way of keeping attention..
Volume has its place, but if you have ever dealt with an icy stare combined with quiet anger then you will know the power of quiet control in comparison to emotional loudness.
So use a quiet voice for power, but use it sparingly.
