CALIBRATION OF SOUND INTENSITY METERS

Objective



The number of measurements of sound power from machines is going to increase after the adoption of the directive on machines. Use of sound intensity techniques requires the calibration of sound intensisty meters although the methods are not at present well established.

The project is therefore structured

- to establish methods of calibrating sound intensity probes;
- to establish methods of determining the directionality of sound intensity probes;
- to establish simplified methods of verifying the calibration of sound intensity probes;
- to establish methods of determining the lowest measurable intensity.

The methods developed in the project will be incorporated in the IEC standard on "instruments for the measurement of sound intensity".
