Generates demand for communication models and techniques for reducing this uncertainty (and risk) about how audiences will respond to messages. Noise=anything that interrupts the movement of message or prevents the intended impact or effect from occurring. 4 types of noise (julia wood: 1) physiological (distraction, fatigue, 2) physical (noisy environment, 3) psychological (bias, values, beliefs, 4) semantic (spelling/grammar problems) Applying the transmission model to science in news and popular media.
