Moviemakers of the suspense, horror and drama genres learned long ago that in order to build tension in the audience, slowly lowering the sound makes moviegoers start to strain to hear the dialogue (and yes, music and other sound is added to build to a crescendo). Tension builds, the muscles in the bodies of the audience tighten, they begin to lean forward slightly and THE HAND FLIES INTO THE SCREEN, GRABS OUR HERO AND THE AUDIENCE JUMPS IN THEIR SEATS SCREAMING!
Works every time.
Now take a technology we’ve used for a long time — conference calling on the Plain Old Telephone System (POTS) — and realize that people calling in on a variety of devices (headsets, cell phones, office phones) add noise and the telephone system (and conference bridge) sample at only a measly 8khz. The result? Tension builds, our muscles tighten and we actually shift our attention (you know who you are….you surfin’ the web folks when you’re supposed to be listening to us on the call!) and the quality of the conference and what we’re trying to communicate to one another suffers.
Let’s look at Skype and how using it decreases tension and increases the quality. Sampling at 16khz means the quality is substantially higher than POTS and is so good that you can hear people breathe, move something on their desk or even click their mouse. The “resolution” of the audio is much higher and thus the call quality is better. The result? Lower tension (or none at all), the callers are relaxed and the communication is higher. Thankfully there are emerging conference bridges that can handle call-ins via Skype and sample at 16khz to maintain call quality (e.g., HighSpeedConferencing).
Let’s take this one step further to other forms of social media: Imagine you hosted a party and when your guests arrived, no one greeted them at the door, clusters of people were broken up into little cliques ignoring them, and as you glanced over at them in the doorway thought, “They’re on their own and are just going to have to figure out how to participate.“
