| Resumen |
Sound intensity as a measure of noise emission from machines has met increasing interest. This report describes the principles of sound intensity measurements, some theory and also the draft proposal for measuring sound power levels adopted in Oct. 1988 by the ISO. Some examples of measuring sound power using the intensity method are given, with measurements on a pistol blowing hot air. The results indicate that sound intensity can be used for determining sound power levels in diferent types of rooms. Pictures of the distribution of intensities can be made with the help of computers. |
