White noise has different defination for different discipline , though underlying principle is same. For a moment, think 'White' as " all strength or value or probability" ( white color has all colors of same strength). Noise as outcome ( wether it has sensible meaning or not in the context). White noise , Statistically speaking, probability of occurrence of each and every elements of interest are same. Now , think , if all letters from English alphabet has a same probability in a word/spelling, in other words all 26 letters in one word, it willmakes it a gibberish/ noise.But all 26 letters form the basis ( complete background or white noise) of writing English words. In sound, if all pitches have same volume. , results is a noise almost if a bullet being fired. Amar Bose, the founder of Bose systems, first came up idea of using bullet sound as source of 'white noise' for testing fidelity of audio system and patented it. Volume of all audible pitches in bullet sound are extremely close for human ear to detect the discrepancy in volumes. Today, all audio electronics and symphony halls uses this sound for testing out its audio fidelity for different pitches. In a ideal hall , echo of bullet will sound exactly ,like ,when it was fired, in reality 80% or better is considered great. white canvas in a painting or photography is ideal 'white noise' background , here; like sound of bullet is a great 'white noise' background for audio designing context. But hail of bullets during a music consert is just undesirable noise. (Like wise a white screen for blocking is not a white noise background in painting or photography.) In pattern reconization, purpose of white noise is completely different. Think of fog as white noise. Extremely dense fog is close to perfect white noise. If you filter white color from the view, that might also remove the white color from any object in the fog , if the object has mostly have white color, little to no chance of discerning it. If fog is half as dense then filtering to about 50% of the above strength ( opaque) will have more success with the same object. In the above visual scenario, different degree of opaqueness can be considered different white noise models , in this context. In the case fog/pattern, filtering out white noise is the objective. Where as, in earlier scenarios, white noise background is used partially at a time ; like using few letters from English alphabets for a legitimate English words. I know, in or two reads,' white noise 'for those who never had to work with it may find it hard to grasp all the purpose, enventually will. Back to Hur and shiv lingo pujas. Those are giving bad taste in people's mouth. Most people moved on from that topic. Now it can only play into the hands of extremist in both religious groups. It is not just Islam or Hindu, even Jews. And Christian legitimize sex slaves. Holy books are redict documents, those many sources. One fact that most people ignore those outrages topics written many decades after the deaths of respective prophets. I will not be supprised some prophets had no idea what was written their name. Most people ignore the stuff in their daily practice. Only extremist refers it. nazi didn't treat hew any better. Dr Mengke inject blue dye and dissect their eyes while they were awake . These are not joking matters. Why put gasoline in fire. |

Experience in the field is much more valuable than "conjectural" knowledge imparted in colleges and universities. You have done well by opting for field experience that made you a better statistician. Your knowledge in this field is much superior to many others! Congratulations! By the way, what is "white noise modeling"? Never heard of it before. Please explain.
