Abstract

A Sound power measurement within a small semi anechoic chamber was undertaken in accordance with ISO Draft Standard 9614 employing a pressure-pressure finite difference probe system with real time band analysis. It was found that F2, designed as an overall surface pressure-intensity indicator, was negative in a particular low frequency band. This result was inconsistent to it's ultimate use within a qualification criterion and in consequence an investigation into the cause was undertaken
