The document discusses various barriers to effective listening, including physical, people-related, physiological, and psychological barriers. Physical barriers include noise, poor acoustics, interruptions, and uncomfortable environments. Physiological barriers are factors like health issues, disabilities, and a wandering attention that make it difficult to focus. Psychological barriers consist of doubts about the speaker, personal anxieties, attitudes like egoism, impatience, and emotional blocks against new ideas. Strategies are provided for overcoming these barriers through focused attention, not interrupting, listening fully before responding, understanding main ideas, asking questions, and providing feedback.
