When we fail to reach any of these objectives, means that something is not working properly in the communication conduct, that something interfered while sending the messages. Everything that interferes with the communication process is called the barrier, difficulty or “noise”.

The communication barriers occur when the receiver of the communicated message, does not receive or misinterpret the desired meaning of the transmitter. The purpose of studying communication is to reduce the reason that causes these phenomena. As I said before, “the meanings are found in humans and not in the words, and so the first step is to identify the factor that leads to incorrect assumptions. These are:

Differences of perception – the way we see world is influenced by our previous experiences so that people of different ages, nationalities, cultures, education, occupation, gender, temperament, etc, will have other perception and they will interpret situation differently.

Rushed conclusions – we see often only what we want to see and heart what we want to hear, avoiding recognizing the reality itself.

Stereotypes – learning constantly from our experiences, there we may face the risk of treating different people as if they were one single. “If I met an engineer (student, merchant, etc), I have met them all”.

Lack of knowledge – it is difficult to communicate effectively with someone who has a different education, whose knowledge is much lower about one particular topic. It is certainly possible but it requires skill from the one who communicate; he must be aware of the discrepancy between levels of knowledge and he must adapt accordingly.

Lack of interest – is one of the largest and most common obstacles; where the lack of interest is obvious and understandable, it should be act with ability to direct the message to correspond with the interests and the needs of the person who receives the message.

Emotions – the transmitters and receivers emotionalism can also be a barrier. Strong emotion is responsible for almost complete blocking of communication. One way to prevent this deadlock is to avoid communication when transmitters are affected by strong emotions. However, sometimes the receiver message may be less impressed by a person who speaks whiteout emotions or excitement, considering him boring.

Personality – not just the differences between personality types can create problems but often our own perception of the people around us is affected; consequently, our behavior affects the partner’s behavior.  “Personalities clash” is one of the most common causes of failure in the communication. We are not always able to influence or change the personality, but of the other but, we must be prepared at least to study our own person to see if a change in our behavior can generate satisfactory responses.

Those are just a few factors that can make the communication less effective or even to fail completely. The potential barriers of communication not only depend on the receiver/ transmitter , but the communication conditions that we must know and also control and so the communication process will have a chance to be effective. Perhaps, this might be a barrier
