Because of its ability to disrupt or obscure a message, noise tends to be one of the most common communication barriers. To overcome noise barriers, you must establish precisely what the source is. Often, this can be the most difficult part as it’s not always clear where exactly the noise...
Indeed, psychological noise is a very important communication problem. ? But the linear model, despite its advantages, suggests that communication flows in one direction, from sender to receiver. Although some types of messages ( printed and broadcast messages, for example) do flow in a one-way...
9.3.7 ‘White noise’ and its interpretation Gaussian‘white’ noise Ntωt∈−∞,∞, in fact, is a model for a ‘completely’ random process whose individual random variable Nt=t′,ω is normally distributed. As such, it is an idealization of stochastic phenomena encountered in engineering...
Using this representation, a number of results in communication theory are deduced concern- ing expansion and compression of bandwidth and the threshold effect. Formulas are found for the maximum rate of transmission of binary digits over a system when the signal is perturbed by various types of ...
Theorem 1 has been given previously in other forms by mathematicians3 but in spite of its evident importance seems not to have appeared explicitly in the literature of communication theory. Nyquist,4, 5 however, and more recently Gabor,6 have pointed out that approximately numbers are sufcient,...
While fashion is a form of self-expression, it’s also important to recognise its social impact. What you wear can affect how others perceive you and how you interact with the world. Dressing appropriately for different occasions—whether it’s a business meeting, a casual gathering, or a fo...
Speech communication often takes place in noisy environments; this is an urgent issue for military personnel who must communicate in high-noise environments. The effects of noise on speech recognition vary significantly according to the sources of noise, the number and types of talkers, and the lis...
The role of the central nervous system is to differentiate between the information-carrying component in the neural signal and irrelevant noise that interferes with that signal. Still, the irrelevant noise remains a vital element for successful intraneuronal communication, as the central nervous system...

Noise can interfere with acoustic communication by masking signals that contain biologically important information. Communication theory recognizes several ways a sender can modify its acoustic signal to compensate for noise, including increasing the source level of a signal, its repetition, its duration,...
