Acoustic shock: an update review.

BACKGROUND

This paper discusses the concept of acoustic shock based on a literature review and the results of our own research into cases seen in both clinical and medicolegal practice. With the demise of traditional 'metal bashing' and 'smoke stack' heavy industries, there has been a decline in the incidence of noise-induced hearing loss and tinnitus in this form of employment. However, with the increasing establishment of call centre work, the emergence of acoustic shock has been noted. Acoustic shock is recognised as a clinical entity distinct from noise-induced hearing loss and acoustic trauma.

OBJECTIVE

This article discusses clinical implications, medicolegal considerations in light of a recent high-profile court case and proposed criteria for diagnosis.
