The Cost of Noise versus Long-term Benefits of Noise Control
Concerns about the anticipated cost of purchasing new, quieter equipment or of retrofitting existing equipment are pervasive. However, the economic cost of potential disability claims, hearing aids and batteries, hearing protective devices (HPDs), and the hearing conservation program itself must be taken into account. Controlling noise, on the other hand, can preserve both economic and human resources in the long run.
The Long-Term Cost of Noise Exposure 
(David A. Nelson, INCE Bd. Cert., Principal Consultant, Nelson Acoustics) explores methods for assessing the cost of noise exposure and the benefits of noise reduction.
The Long-Term Economic Benefit of Noise Control spreadsheet performs computations to estimate the net benefit of current noise control expenditures versus the anticipated cost of noise induced hearing loss at a later date.
