Title: Investigation Of Sound Power Determination Methods Aiming The Domestic Electric Drill's Stamping Program
Author: Bertoli S.R.
Dos Santos C.
Abstract: Sound power radiated by a source is an important parameter to control noise. In Brazil, IBAMA (Instituto Brasileiro do Meio Ambiente e dos Recursos Renováveis) and INMETRO (Instituto Nacional de Metrologia, Normalização e Qualidade Industrial) started a program named "Selo Ruído" that labels the household appliances according to the noise level produced by them. There is a forecast to include the electric tools in this label program. The drill is one of these electric tools that will be included. This work presents tests of drills with different standard methods for determination of the sound power levels. The methods used for the tests were the ones that use reverberation rooms (ISO 3743 - Engineering Methods for Special Reverberations test Rooms and ISO 3741 - Precision Methods for Special Reverberations test Rooms). These methods are referenced by Brazilian standard NBR 13910:1997 - Part 1 - "Diretrizes de ensaios para a determinação de ruído acústico de aparelhos eletrodomésticos e similares". A quantitative analysis from results obtained with different methods applied was performed. The analysis allowed to propose the method to be used in the drill's stamping Brazilian program (Selo ruído).
