This document discusses different types of barriers to communication. It identifies four main types: intrapersonal, interpersonal, organizational, and semantic. Intrapersonal barriers stem from individual differences in experience, education, values and personality that cause people to interpret information differently. Interpersonal barriers occur due to inappropriate words between people. Organizational barriers can happen due to a rigid hierarchy that restricts information flow and introduces multiple transfer points that can distort or delay messages. Effective communication requires being aware of these potential barriers and taking steps like creating an open environment, considering the receiver, minimizing handoffs, and using appropriate nonverbal cues and media.
