This document discusses various barriers to effective communication. It identifies physical, semantic and language, socio-psychological, organizational, and cross-cultural barriers. Physical barriers include faulty organizational structure, noise, time and distance, and information overload. Semantic and language barriers arise from differences in meanings, pronunciations, and the multiple meanings of words. Socio-psychological barriers stem from attitudes, emotions, filtering of messages, and status differences. Organizational barriers occur from the structure and flow of information in organizations. Cross-cultural barriers relate to differences in language, values, social relationships, concepts of time and space, and gestures across cultures. The document also provides some suggestions for overcoming these barriers to communication.
