The scope of the Symposium included hearing protector design and development, protector standards, protector attenuation measurement, civil and military usage of hearing protection and hearing conservation. The main conclusion drawn from attendance at this meeting is that work on hearing protection in Europe is, in many respects, in advance of that in the US and Canada. The papers presented by Rood, Chillery, Brinkmann, Damongeot, Martin, Wilkins and Gorman all show a constructive attack upon the urgent problems of protector design and performance. In evaluating the relevance of current work it is particularly instructive to recall the summary of problems presented by Shaw. Apart from the objective measurement of ear-plug attenuation, all the problems are being addressed by the above authors. Current work at RAE is well represented by this list. In addition to the development of the miniature microphone method of measuring ear-muff attenuation work is proceeding upon an active noise reduction system, correlation between objective and subjective data, correlation between laboratory and field data and the measurement of headband force.
