Environmental noise can be any external noise that can potentially impact the effectiveness of communication. [2] These noises can be any type of sight (i.e., car accident, television show), sound (i.e., talking, music, ringtones), or stimuli (i.e., tapping on the shoulder) that can distract someone from receiving the message.

Barnlund's model of communication is one of the most well-known transactional models of communication. It was published by Dean Barnlund in his 1970 article A Transactional Model of Communication. [6] [13] [19] It is based on the idea that there are countless external and internal cues present. Communication consists in decoding them by ...
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
Another model of communication was proposed by Dean Barnlund in 1970. [43] [39] [44] He aims to give an account of communication that encompasses both its interpersonal and its intrapersonal side. He identifies communication not with the transmission of messages but with the production of meaning in response to internal and external cues.
External noise consists of outside influences that distract from the communication. [72] Internal noise is described as cognitive causes of interference in a communication transaction. [72] In the hospital setting, for example, external noise can include the sound made by medical equipment or conversations had by team members outside of patient ...
Telecommunication systems strive to increase the ratio of signal level to noise level in order to effectively transfer data. Noise in telecommunication systems is a product of both internal and external sources to the system. Noise is a random process, characterized by stochastic properties such as its variance, distribution, and spectral density.

The first transactional model was proposed by communication theorist Dean Barnlund in 1970. [39] He understands communication as "the production of meaning, rather than the production of messages". [40] Its goal is to decrease uncertainty and arrive at a shared understanding. [41] This happens in response to external and internal cues.
