Helmeted navy divers are exposed to high levels of noise from self-generated mechanisms, such as regulator exhaust, and external sources, such as underwater tool-generated noise. Noise exposure limits can be easily exceeded especially if effective communications through helmet-mounted speakers is required. A multi-faceted approach is proposed to reduce self-generated noise as well as overall helmet-transmitted noise from external sources such as tools. Modeling, analysis, design and initial testing will be performed.
