It also allows a tradeoff between the number of events and the maximum permitted sound level. New York (Chapter 150) also trades off overall levels with the duration of the sounds. Colorado (Article 25-12-109) declared that noise restrictions on shooting ranges is a detriment to public health, welfare, and morale.
The most fertile areas for roadway noise mitigation are in urban planning decisions, roadway design, noise barrier design, [14] speed control, surface pavement selection, and truck restrictions. Speed control is effective since the lowest sound emissions arise from vehicles moving smoothly at 30 to 60 kilometers per hour.
Environmental noise regulations usually specify a maximum outdoor noise level of 60 to 65 dB(A), while occupational safety organizations recommend that the maximum exposure to noise is 40 hours per week at 85 to 90 dB(A). For every additional 3 dB(A), the maximum exposure time is reduced by a factor 2, e.g. 20 hours per week at 88 dB(A).
The U.S. noise standards are defined in the Code of Federal Regulations (CFR) Title 14 Part 36 – Noise Standards: Aircraft Type and Airworthiness Certification (14 CFR Part 36). [111] The FAA also pursues a program of aircraft noise control in cooperation with the aviation community. [ 112 ]
Water shortage and water restrictions have been current local issues, and a few new Gold Coast residential areas have recently included dual reticulation in their planning and development to supply water from a new water recycling plant being built concurrently.
Noise barriers can be effective tools for noise pollution abatement, but certain locations and topographies are not suitable for use of noise barriers. Cost and aesthetics also play a role in the choice of noise barriers. In some cases, a roadway is surrounded by a noise abatement structure or dug into a tunnel using the cut-and-cover method.
