The need for training in listening is a problem which has baffled educators for years. Studies demonstrate the tremendous amount of time that we spend in listening within our communication time. Paul T. Rankin's classic study gave us some working percentages, percentages which have held up in other, more recent, research projects. Through his analysis, Rankin discovered that we spend 75% of our time in oral communication. Of that time, approximately 45% is spent in listening and 30% of our time in speaking.
