A sound increase of three dBA is barely noticeable by the human and a 10 dBA increase is heard as twice as loud. For example, ifi.e., the amount of traffic doubles), there is a three dBA increase in noise, whi other hand, if traffic increases by a factor of 10, the resultin heard as twice as loud. Traffic volumes in the project area are either on roadways that or, the traffic levels attributable to the project are well belo that could be noticeable. Residential areas exist on US 10 betwe96 and I-35W, as well as along CR 96 to the east of the project. The highest traffic volume generated by the project is projecte vehicles per day on US10 between CR 96 and I-35W, which is approximately 10 percent of the background total daily traffic volume of approximately 50,000 that will exist on generated by the project on CR 96 east of the project area is pr day, which is approximately 40 percent of the background total d will exist on this roadway segment. Noise walls are currently beand along US 10 for a short distance north of CR 96, as part of the The AUAR study area will be developed such that any land use act sufficient setbacks from existing noise sources to thereby reduc details will be determined as the project development proceeds.
