The document discusses different types of barriers to communication. Intrapersonal barriers occur due to differences between individuals in experience, education, values and perceptions. Interpersonal barriers happen in interactions between two or more people due to issues like poor communication skills and emotional outbursts. Organizational barriers exist within entire organizations as messages pass through hierarchical systems and each transfer point risks distorting the message. Some causes of barriers are wrong assumptions, varied backgrounds, fear of superiors, and inappropriate media use. Effective communication requires creating an open environment, considering the receiver, limiting transfer points, controlling emotions, and analyzing feedback.
