1. Physical Barriers: Environmental factors that include closed doors, faulty equipment, or loud surroundings are designed to literally obstruct a person from hearing or concentrating.

2. Psychological Barriers: Personal troubles, stress, anxiety, or a lack of confidence may affect how people send or receive messages.

3. Language Barriers: Language, jargon, or semantics put people in a predicament to be misunderstood—most especially in multicultural or cross-functional teams.

4. Cultural Barriers: Workplace norms change from region to region. Gestures, expressions, and even silence mean something different across cultures.

5. Organisational Barriers: Hierarchies, silos, and vague reporting lines act as barriers to communication, blocking feedback from below, for example.

6. Perceptual barriers could be how one perceives reality – tone, body language, or mere facial expression – leading to false assumptions.

7. Emotional barriers prevent people from speaking their minds, fearing that they may be judged, criticised, or confronted.

8. Interruptions and physical distractions: Constant interruptions, continuous noise, and constant alerts stop active listening and processing of information.

9. Stereotyping will in fact disrupt or hamper what one person is trying to communicate based on race, gender, or background, all of which affect openness and clarity in communication.

These overcoming barriers to communication examples show how such disruptions in the present working systems may impact collaboration in the absence of intervention.
