Noise damage to hearing health is a health risk which is associated with both civilian and military occupations as well as certain leisure activities. Occupational noise damage to hearing must date from the bronze age, when man first began to fashion metals some five thousand years ago. The rapid growth of industrialisation over the past two centuries has produced what might be termed as the current civilian epidemic of occupational noise induced hearing loss. This series seeks to address points relevant to current knowledge of the subject. The volume should prove useful to members of the many disciplines that have an interest in this subject.
