Basics On Noise And Weighting Filters

What is Noise? No matter what type of noise you wish to consider, whether it is transportation noise, occupational noise, entertainment noise, or general community noise, it helps to have an understanding of what noise is. Noise is unwanted sound. What is a “noise” to you may be a sound to someone else; there is always a subjective component to the term. A sound is produced when something vibrates rapidly enough to generate a disturbance or pressure wave in the surrounding medium. Most sounds are created by vibrating surfaces and turbulent air.
