This document discusses physical and external barriers to communication. Physical barriers are environmental or workplace conditions that interfere with communication, such as noise, inadequate space, faulty equipment, or different buildings. External barriers are outside factors like noise, climate, distractions, or technical problems. Some ways to overcome barriers include ensuring the timing and location are appropriate, using clear language, providing feedback, and consistency in messages. Physical barriers can be addressed by improving workplace design, equipment, and reducing distractions and noise during communication.
