Abstract
The more stringent regulations issued by the brazilian environmental agency CONAMA, regarding the controlling of vehicular noise emissions, indicates the use of the national standard NBR9714.
The application of the criteria described in this standard to the normal procedures for fleet control is discussed in this work. Computer simulations are used to analyse the environmental influences to be expected. Actual measurements are done to validate the simulation results. An integrated system to automate the measurements and the report generation is presented.
