This document discusses different types of communication barriers: physical, emotional, gender, organizational, perceptual, cultural, and language barriers. It provides factors that can cause each barrier and recommendations for overcoming each one, such as using technology, workshops, clear language, and creating an open culture. The key barriers to effective communication are anything that limits the message between sender and receiver, including distractions, distances, misunderstandings, disabilities, fears, biases, policies, perceptions and cultural differences. Overcoming barriers requires techniques like listening, clarifying misunderstandings, addressing biases, unifying visions, and choosing environments and mediums carefully.
