Noise Control and Speech Intelligibility Improvement of a Toll Plaza.

摘要

Vehicular toll roads are one component of many municipal transportation systems. Personnel working at toll collection plazas are exposed to extended, continuous traffic noise. Sustained noise levels of this nature may cause hearing loss, induce fatigue or stress, and reduce worker productivity. The objective of this research is to lower the noise levels experienced by toll collection workers and increase the speech intelligibility of the tollbooth environment.
