Communication requires a sender, message, and recipient. However, barriers can occur that interfere with effective communication. The document discusses several types of barriers: physical (time, place, noise, space), perceptual (differences in perspective, values, attitudes), emotional (fear, insecurity, mistrust, stress), cultural (differences in rules between cultures), language (inability to speak the same language), and gender (differences in how men and women communicate). To overcome these barriers, the document recommends being aware of them and taking steps such as listening, clarifying misunderstandings, controlling emotions, using interpreters, and building understanding between genders.
