There are 4 types of noise:

- Physical noise: it comes from the environment, like the noises people make, extreme temperatures, and places with many people.
- Psychological noise: it indicates that a person has some qualities that influence the way he/she communicates and understands what other people say.
- Semantic noise: it takes place when there is a problem of comprehension of words between two or more people.
