Noise pollution differs from other forms of pollution in a number of ways. Noise is transient; once the pollution stops, the environment is free of it. This is not the case with air pollution, for example. We can measure the amount of chemicals and other pollutants introduced into the air. Scientists can estimate how much material can be introduced into the air before harm is done. The same is true of water pollution and soil pollution. Though we can measure individual sounds that may actually damage human hearing, it is difficult to monitor cumulative exposure to noise or to determine just how much noise is too much. The definition of noise pollution itself is highly subjective. To some people the roar of an engine is satisfying or thrilling; to others it is an annoyance. Loud music may be a pleasure or a torment, depending on the listener and the circumstances. The word transient in the passage is closest in meaning to:   Temporary
