GIRALDO A., William A.  e  GONZALEZ FERNANDEZ, Alice Elizabeth. Unit timing for environmental noise measurements. Rev. ing. univ. Medellín [online]. 2011, vol.10, n.18, pp.61-68. ISSN 1692-3324.

The managers of environmental noise measurements in environmental control agencies, or in general every person that work in this subject, have to think on the representativity of the unit measurement time interval, and how to evaluate it in order to get good quality results regarding the unit measurement time without increasing the measurement costs. A methodology for deciding if a certain measuring time interval -in this case, fifteen (15) minutes- is representative of noise pressure levels occurring during one hour, is proposed in this paper. This methodology allows to optimize the use of stationary sound level meters and to propose a strategy for reducing the costs of environmental noise measurements and of the designing of noise maps in general.
