Noise may be created by the internal factors such as perception, attitude, personality, culture, physical health etc. These factors can influence the ability of receiver to understand the message of sender effectively. For example if a student is attending a lecture and at the same time he is thinking about the football match then in such case thinking is internal factor of noise which distracts the student to pay his attention to the lecture. Other types of noise are feeling ill or tired, stereotypes, biases, reputations etc.
Semantic
If the receiver does not understand the language used by the sender of message or if the sender uses various jargons which the receiver does not understand then such type of noise is considered as semantic. In such type of communication sender and receiver do not have shared meaning in communication. In many cases, the professionals such as businessmen, accountants, lawyers, doctors etc use terminologies which are not understandable by layman.
