Previous studies concerning the categorisation method have been based on
short daytime measure- ments. These studies demonstrated urban-noise
stratification in the daytime. Nevertheless, legislation and standards
refer to noise estimation throughout the day. This paper presents the
first attempt to apply the categorisation method to indicators obtained
through long-term measurements. The study was conducted in Plasencia,
Extremadura (Spain) which has approximately 41,500 inhabitants. First, we
conducted a stratification of the roads using the categorisation method.
Second, long-term measurements (approxi- mately one week) were conducted
at different sampling locations across different categories of streets.
The results were analysed by category. Moreover, the profile of the
noise-level variation was analysed during the day. The results revealed a
stratification of sound levels measured across the different categories.
Furthermore, we found health risks due to the noise levels in this town.
Short-term measurements were also conducted to complete the categorisation
method suitability analysis.
