Ubiquity reported that in 1971, Albert Mehrabian published a book called Silent Messages, in which he discussed his research on non-verbal communication among salespeople. He concluded 55% of effectiveness is body language, 38% voice and only 7% is the salesperson's actual words. Others have said the mix for most presenters is 70% what you look like, 23% what you sound like and 7% what you say.
Whichever numbers you believe, the impact is simple: your look and how you sound may be significantly more important to your influence than what you say. Add into this what Stanford University called ‘Zoom Fatigue’ and it becomes important for those of us working from our home offices to maximize those things to make us more effective on our calls.
At BRAVAS, we would recommend you focus on two things when improving your video conferencing solutions: a better camera and a better microphone.
