Noise Exposures in America

Please note: exam questions are subject to change.

1. Which of the following statements is true? Noise exposures represent an environmental injustice, since marginalized and/or minority groups appear to experience higher exposures than other groups. Noise exposures do NOT represent an environmental injustice, since marginalized and/or minority groups do NOT appear to experience higher exposures than other groups. Noise exposures are not a form of environmental exposure and so cannot represent an environmental injustice. Noise exposures are not harmful and so by default cannot represent an injustice.
2. Which of these statements is true? More than 3/4 of Americans have noise exposures in their communities that exceed levels recommended by the Environmental Protection Agency to protect public health. More than 2/3 of Americans have noise exposures in their communities that exceed levels recommended by the Environmental Protection Agency to protect public health. More than 1/2 of Americans have noise exposures in their communities that exceed levels recommended by the Environmental Protection Agency to protect public health. More than 1/3 of Americans have noise exposures in their communities that exceed levels recommended by the Environmental Protection Agency to protect public health.
3. Long-term average noise exposures that exceed what A-weighted decibel (dBA) level can cause noise-induced hearing loss? 60 dBA 70 dBA 80 dBA 90 dBA
4. Which of the following is NOT a resource or research study that is currently available to evaluate noise exposures and associated health risks? The US/Canada Job Exposure Matrix for Occupational Noise The US National Transportation Noise Map The US Community Noise Databank The Apple Hearing Study
5. Which of the following strategies can be used to raise awareness and/or reduce noise exposures in America? Provide additional information on noise exposures and associated health impacts to stakeholders Regulate the noise levels produced by different noise sources Create noise maps to estimate noise exposures across US communities and populations All of the above
