Economic Impact of Hearing Loss and Reduction of Noise-Induced Hearing Loss in the United States.

PURPOSE

Hearing loss (HL) is pervasive and debilitating, and noise-induced HL is preventable by reducing environmental noise. Lack of economic analyses of HL impacts means that prevention and treatment remain a low priority for public health and environmental investment.

METHOD

This article estimates the costs of HL on productivity by building on established estimates for HL prevalence and wage and employment differentials between those with and without HL.

RESULTS

We estimate that HL affects more than 13% of the working population. Not all HL can be prevented or treated, but if the 20% of HL resulting from excessive noise exposure were prevented, the economic benefit would be substantial-we estimate a range of $58 billion to $152 billion annually, with a core estimate of $123 billion. We believe this is a conservative estimate, because consideration of additional costs of HL, including health care and special education, would likely further increase the benefits associated with HL prevention.

CONCLUSION

HL is costly and warrants additional emphasis in public and environmental health programs. This study represents an important first step in valuing HL prevention-in particular, prevention of noise-induced HL-where new policies and technologies appear promising.
