The following documents will help you demonstrate the value of noise control measures.
Cost-Benefit Analyses
- Center for Naval Analysis report on Long-term cost benefit of noise control on ships
—Analysis of the life-cycle cost of noise exposure aboard a US Navy vessel (US Navy) - Model for Estimating Life-Cycle Costs Associated with Noise-Induced Hearing Loss —Predicting the Life-Cycle Costs associated with hearing loss in a particular population (Sachs, Weatherby, Tufts, January 2007)
- Noise Exposure and Acquisition Tool (NEAT) Briefing Draft —Developed by the DoD/US Navy; illustrates life cycle costs due to noise exposure, calculates speech interference levels for noisy environments, illustrates potential cost savings from integrating noise controls in the acquisition phase (Geiger, Cobb)
- Demonstrating the Business Value of Industrial Hygiene —A detailed effort by the American Institute of Industrial Hygiene to demonstrate the business case for industrial hygiene in general.
Hearing Loss Estimation
- Performance loss as a function of hearing loss —Analysis of a crew’s expected performance loss in a higher noise environment. (US Navy)
Calculators
- Center for Naval Analyses Hearing Loss Calculator
—A spreadsheet calculator accompanying the above report, which computes the life-cycle cost of noise exposure aboard a US Navy vessel (US Navy) - Noise Exposure and Acquisition Tool Users Guide —A guide to the implementation of the NEAT tool.
- Noise Exposure and Acquisition Tool Spreadsheet —The NEAT spreadsheet that performs cost-benefit calculations.
