Summary:Wittje discusses that the definition of noise has evolved through history from an acoustical term informed by music to a plurality of meanings. Today one person's noise may be someone else's signal. Noise is associated with various phenomena, ranging from unwanted sounds to random fluctuations in thermodynamic systems. Beyond it being an acoustic property, scientists now regard noise as a limiting factor in information theory and measurement processes. One of the most fascinating topics in science is the development of the various, sometimes even contradictory, meanings and concepts of noise.
