A communication barrier is an impossibility that someone has to receive or understand the messages (the message can be lengthy or complex so you do not understand) others send. These barriers can be internal (has to do with thoughts, ideas or feelings for example when you have no interest at all, when you have problems with listening skills, when you have personal problems) or external (has to do for example with noise in the air, so you cannot hear well, problems with technology, etc).
