I. Noise
Noise refers to the distraction and interference in the environment in which communication takes place. This affects the accuracy, clarity or event the arrival of the message.
Noise can be further classified into four different types.
1. Physical noise.
2. Technical noise.
3. Social noise.
4. Psychological noise.
1. Physical noise
Obstruction caused by environmental factors is termed as physical noise.
Physical noise may include noise of the other people taking, passing of traffic, passing of people near the communicating area. This may prevent a message from being heard clearly.
2. Technical Noise
This noise involves the failure of the medium of communication. It includes, crackle on the telephone line or illegible handwriting etc. This may prevent the exchange of communication.
3. Social Noise
It is the interference caused by differences in personality and cultures of the members communicating. It includes difficulties faced by people who have different in ages, castes, social status etc.
4. Psychological Noise

The same message received when sender are angry is often interpreted differently when sender are happy. Extreme emotions such as jubilation or depression are most likely to hinder effective communication.
1. Types of barriers to communication

On the low end of the scale, noise such as radio station static is a minor irritant that hampers but does not completely block the transfer of understanding. But at the high end of the scale noise can become an impenetrable barrier to communication. There are four types of communication barriers that represent extreme forms of noise:
1: Process barriers
2: Physical barriers
3: Semantic
