The U.S. Department of Transportation's Bureau of Transportation Statistics has created a National Transportation Noise Map Archived 21 January 2018 at the Wayback Machine to provide access to comprehensive aircraft and road noise data on national and county-level. The map aims to assist city planners, elected officials, scholars, and residents ...
For train and road traffic noise, the description of the sources is usually made in terms of parameters such as speed, number of vehicles etc. Measurements are used for the validation of results. For industrial noise map production, the most important thing is the description of noise sources: sound power levels (emission), directivity, working ...
Roadway noise is the most prevalent form of environmental noise.Pictured: São Paulo, Brazil. Roadway noise is the collective sound energy emanating from motor vehicles.It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements.
Many pilots regard the Potomac River approach pattern at National Airport as one of the more interesting landing approaches in the United States [60] Boeing flew a 787-8 Dreamliner into DCA in 2011. It is one of the only wide-body aircraft to ever land at the airport. Reagan National Airport has some of the strictest noise restrictions in the ...
Noise is audible from the Columbia neighborhood to South Hill. Many Bellingham residents, especially those in the South Hill neighborhood, have been calling 911 and complaining to city officials ...
The National Transportation Library (NTL) maintains and facilitates access to information necessary for transportation decision-making in government and coordinates with public and private transportation libraries and information providers to improve information sharing among the transportation community.
Traffic noise may include: Roadway noise; Railway noise; Aircraft noise; See also. Ambience (sound recording) Environmental noise; Noise pollution
Noise measurement can also be part of a test procedure using white noise, or some other specialized form of test signal.In audio systems and broadcasting, specific methods are used to obtain subjectively valid results in order that different devices and signal paths may be compared regardless of the inconsistent spectral distribution and temporal properties of the noise that they generate.
