摘要：	Two surveys were administered to tollbooth employees working at a toll collection plaza located in Indiana. The first was used to evaluate employees' subjective response to the ambient noise levels in their occupational environment. The results confirmed that ambient noise is perceived as undesirable and hampers communication between operators and patrons. In the second survey tollbooth attendants were asked to evaluate a specific type of open ear active noise control headphone and rate its performance with respect to noise reduction, speech intelligibility, and comfort. The results showed that the active headset effectively reduced ambient noise, but its ability to improve speech intelligibility could not be demonstrated. Additionally, the active headset was found to cause slight discomfort.
