Which of the following is NOT a barrier to communication?

The calibration of equipment is not considered a barrier to communication in the context of interpersonal or group interactions. Instead, it is related to the technical aspects of ensuring that devices used for communication or diagnostic purposes function correctly. While equipment that is out of calibration may hinder the effectiveness of tools like CT scanners or communication devices, it does not encompass the barriers that arise from human interactions, such as language differences, cultural misunderstandings, or misreading nonverbal cues.

Language differences can lead to misunderstandings when parties do not share a common language, while cultural misunderstandings stem from varying interpretations and practices shaped by different social backgrounds. Misreading nonverbal cues can create further complications, as body language, facial expressions, and gestures may not convey the intended message accurately. Thus, the calibration of equipment distinctly stands apart from these human-centric barriers to effective communication.
