Auditory and Nonauditory Risks Related to Roadway Traffic Noise: An Overview for Audiologists

Abstract

Purpose: Roadway traffic noise is recognized as a public health concern as it is associated with negative auditory and nonauditory health outcomes. This article provides an overview of roadway noise exposure and the related negative health consequences. The overview specifically includes information on the sources of roadway traffic noise, noise exposure measurement techniques, historic and current U.S. policy regarding roadway noise exposure, and practical suggestions for audiologists for mitigating the negative consequences of excessive roadway noise exposure. The purpose of this overview is to educate audiologists of these effects. Conclusions: Roadway traffic noise exposure is a public health concern both nationally and globally. Nonauditory effects of excessive roadway noise exposure are better understood than auditory effects; however, more evidence is needed to thoroughly to assess the risks to the public. Opportunities in the United States exist at the federal and local level to better understand the effects of roadway traffic noise and mitigate undesirable auditory and nonauditory health consequences. To address noise exposure as a growing public health concern, audiologists should be aware of the effects that roadway noise exposure has on the general population as well as provide education and preventative health care services.
