Noise means the standard deviation of the fluctuations in CTN expressed as a percentage of the attenuation coefficient of water. Its estimate (Sn) is calculated using the following expression:
Noise means two times the root mean square of ten standard deviations, each calculated from the zero responses measured at a constant frequency which is a multiple of 1,0 Hz during a period of 30 seconds.
Noise means any sound which disturbs humans or which causes or tends to cause an adverse psychological or physiological effect on humans.
Examples of Noise in a sentence
Contractor shall operate, conduct, or construct without violating the City’s Noise Abatement Ordinance codified in the SDMC.
Noise levels, especially after 9 pm, should be kept to a minimum.
The project is not identified as a Type 1 project under 23 CFR 772 or the Caltrans Traffic Noise Analysis Protocol.

Specialized areas are Environmental Control, Communicable Disease, Water Safety, Food Safety, Land Use, and Noise Control, or other area deemed to be a specialty by the parties.
More Definitions of Noise
Noise means the standard deviation of the fluctuations in CTN expressed as a percentage of the attenuation coefficient of water. Its estimate (Sn) is calculated using the following expression:100 × CS × sSn = mw where:CS = Linear attenuation coefficient of the material of interest. mw = Linear attenuation coefficient of water.s = Estimated standard deviation of the CTN of picture elements in a specified area of the CT image.
