The U.S. Department of Transportation in cooperation with FHWA and several state transportation agencies is collecting a highway noise database for the development of noise-level regression equations. These data and equations will provide the foundation for the new traffic noise software, TNS. In addition to collecting reference energy mean emission level data, this test plan also requires an extensive database of source heights and subsource spectra covering all vehicle classes and possible roadway parameters. A description is provided of a turnkey rapid data acquisition and analysis system that was developed to collect a large database of vehicle noise source heights and subsource spectra for subsequent incorporation into TNS. Included is a summary of the analysis algorithm used to calculate the source heights, a description of the data collection system, and a brief summary of the data collected to date.

Abstract The work is devoted to the peculiarities of acoustic pollution of roadside territories. The studied territory is characterized by uneven acoustic load on the experimental sections of the highways of the Republic of Crimea, which is associated with the peculiarities of traffic flow and technical characteristics of cars. The article considers the indicators of the equivalent and maximum levels of motor vehicle noise. As the research result, the excess of noise level from 10 to 30 dBA was revealed. The maximum level of acoustic pollution was recorded in 10-meter zone, at a distance of 30 m from the noise source the level of acoustic pollution is reduced to 5-10 dBA.
