1. INTRODUCTION
It has been observed that some divers experience auditory problems as a result of exposure
to high noise fields underwater. These difficulties include conditions such as hearing
loss, vertigo, and bleeding from the ears. The noise sources that appear to be at the root
of these problems are operation of underwater power tools, impact noise (such as
explosions), engine noise, and air turbulence in diving helmets. While the actual correlation
of these detrimental auditory effects with the cited sources is not known, it is believed
that a causal link exists. Accordingly, the focus of this chapter will be on the potential
threat of underwater noise to good hearing-and on theoretical explanations basic to
these problems.
