This document discusses the various barriers to effective communication. It identifies physical, psychological, mechanical, message-related, cultural, linguistic, semantic, gender, organizational, and physiological barriers that can interfere with the exchange of ideas. Physiological barriers relate to the physical or mental state of the sender or receiver, such as sensory dysfunctions or other physical impairments. Psychological barriers stem from human psychological issues like attitudes, emotions, selective attention, and differences in status or experience between communicators. Overcoming barriers like noise, distance, age, incomplete information, and attitudes can improve communication.
