If excessive noise is not reduced to a reasonable level straight away following the issue of an excessive noise direction the noise control officer accompanied by a Police officer may enter the premises and remove whatever is causing the noise or re For most applications noise and vibration can be controlled using four methods 1 absorption 2 use of barriers and enclosures 3 structural damping and 4 vibration isolation Although there is a certain degree of overlap in these classes each method ma 1 White Noise White noise is a basic concept underlying the modeling of ran dom disturbances such as sensor noise environmental disturbances In contrast to continuous time white noise is straightforw ard to characterize in discrete time De64257nition Marc Naguib.

The attenuation produced, in dB per meter run of duct, depends ‎on α, the sound absorption coefficient of the lining material and the ratio of perimeter to cross ‎sectional area of the duct (P/S).‎.
