Construction activities inherently generate substantial noise. As a result, construction becomes a notable source of ambient sound that permeates populated areas daily. This sound, especially at extreme volumes, can be the source of significant public annoyance and anger. Studies have shown that prolonged noise exposure can lead to hypertension, distraction, and even cognitive impairment in children. For these reasons, local governments will set noise ordinances to limit when and at what volume construction sounds can be made. The purpose of this study was to determine the effectiveness of these noise ordinances set by the city of San Luis Obispo. The effectiveness was gauged by the level of satisfaction of residents neighboring four distinct job sites. Interviews were conducted with neighbors and contractors. Additionally, decibel readings were taken at the jobs to determine contractor compliance with volume limits. All four jobs had readings well below the city limit of 75 dBA. Every neighbor that was interviewed had either a neutral or positive impression of the sound emitted from sites. Lastly, all four contractors were void of noise complaints. It can be reasonably concluded that the noise ordinances effecting residential construction in the city of San Luis Obispo are working as intended.
