| nitrogen oxides (Oxides formed and released in all common types of combustion; they are formed by the oxidation of atmospheric nitrogen at high temperatures. Introduced into the atmosphere from car exhausts, furnace stacks, incinerators, power stations and similar sources, the oxides include nitrous oxide, nitric oxide, nitrogen dioxide, nitrogen pentoxide and nitric acid. The oxides of nitrogen undergo many reactions in the atmosphere to form photochemical smog) |

| noise abatement (Measures to reduce noise at the source, to encourage quieter technologies or equipment or to prevent or reduce the propagation of sound. Measures may include the isolation and damping of vibration sources; the replacement of components with quieter parts and material; the enclosure of particularly noisy components; the provision of noise barriers, etc.) |

|
| noise analysis (Determination of the frequency components that make up a particular noise being studied) |

|
| noise barrier (Barriers for reducing the propagation of sound: they are widely used in industry and alongside roads and railways to shield receivers from noise sources. Barriers will not reduce the noise on the receivers side, but will increase it, unless the barrier is also covered in absorbing material) |

| noise disturbance (Noise interferes with communication and interferes with thought processes. Noise interferes with sleep, it causes anger and frustration, and has been implicated as a contributor to various psychological and physiological problems. Noise detracts from the quality of life and the environment) |
