Noise refers to anything that disrupts or affects the process of communication between a speaker and a listener/listeners. Noise can be either external (a physical sound), or internal (a disturbance in the mind).
There are 4 types of noise:Physiological noise: it originates because a person is hungry, tired, has a headache, is taking medication, or there is some other factor that influences his/her perceptions.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.
