This document discusses communication barriers and identifies four main types: physical/mechanical, semantic/language, personal socio-psychological, and cross-cultural. Physical barriers include issues with the communication medium or noise that disrupts the message. Semantic barriers occur due to differences in word meanings or unfamiliar terminology. Personal barriers stem from individual emotions, values, and listening skills. Cross-cultural barriers arise from differences in shared cultural values and attributes that influence how people communicate. Overcoming these barriers requires selecting the right medium, clearly defining terms, and understanding different cultural communication styles.
