The six levels suggested in the article could also serve as a guide for speakers. If you're trying to convey important information and the listener just doesn't seem to get it, ask yourself whether you are expecting them to engage in a higher, more demanding level of listening than they are currently able to. For example, the article says that 80% of what most people try to communicate occur at Level 4: body language. But if you can convey at least some of that information verbally, you'll be able to achieve similar results even if the listener is only at Level 3. This is especially useful if the listener is on the other side of a phone call or an internet forum.
