The continuing development of the circumaural hearing protector requires control of the quality of this device. Current standard methods of protector attenuation measurements are expensive and time-consuming and wholly unsuitable for the quality control of quantity production. Performance of this task requires an objective test facility or artificial head. This paper describes stages in the development of a facility suitable for quality control work and also useful as a research and development tool.
