      <title>THE ANALYSIS AND CONTROL OF ROLLING NOISE IN URBAN RAIL TRANSIT SYSTEMS</title>
      <link>https://trid.trb.org/View/51937</link>
      <description><![CDATA[When an electric-powered steel wheel transit vehicle moving on straight, continuously welded rail passes an observer, the predominant noise heard is rolling noise.  This is the noise produced by small-scale roughness on the running surfaces of the wheels and rails.  The minute peaks and valleys of the surface roughness excite both the wheels and the rails, which in turn radiate a characteristics broadband noise.  Before cost-effective control of this noise can be developed, the mechanism for its generation must be clearly understood.  The study reported here undertook to develop analytical empirical formulas for the prediction of rolling noise that contain all the important parameters describing the wheel/rail dynamic system.]]></description>

      <title>SUBWAY TUNNEL ACOUSTICS - INFLUENCE OF SOUND ABSORPTION TREATMENT OF TUNNEL WALLS</title>
      <link>https://trid.trb.org/View/51938</link>
      <description><![CDATA[One way of decreasing the noise level in subway systems is to treat the subway tunnel walls with sound absorption material.  This has been done in some sections of the Washington Metropolitan Area Transportation System.  The treatment has consisted of Pyrok spray-on on the lower parts of the walls.  Totally the treatment covers approximately 20% of the circumference.  To study the benefit of the treatment tests have been performed with a cannon as a sound source.  The time history of cannon shots at different distances from the source has been evaluated.]]></description>

      <title>NOISE AND VIBRATION IMPACT OF THE MBTA SUBWAY EXTENSION AT HARVARD SQUARE</title>
      <link>https://trid.trb.org/View/51939</link>
      <description><![CDATA[Federal guidelines for preparation of noise and vibration portions of environmental impact statements for rail transportation projects are minimal.  Discussions could result in a more uniform approach to the preparation of these statements.  Analysis of the noise and vibration environmental impact that may result from extension of a rapid transit line of the Massachusetts Bay Transportation Authority in Cambridge, Mass., is presented.]]></description>

      <title>RAIL RAPID TRANSIT ASSOCIATED NOISE ANALYSIS</title>
      <link>https://trid.trb.org/View/51940</link>
      <description><![CDATA[This paper presents a simple analytical model for predicting wayside noise levels attributed to moving rail rapid transit trains.  The physical problem treated by the model is defined as follows: given the receptor location relative to the rail track, the characteristics of passing trains (e.g., speed, length, headway, and the type of train), the rail track configuration (e.g., with or without sound barrier, and at-grade, elevated, or depressed roadbed), and the time period of interest, find the cumulative noise distribution at the receptor.  The model provides a convenient method for analyzing potential community rail noise impacts for use in the planning and design of rapid transit projects.]]></description>

      <title>COMPUTER-ASSISTED PLANNING FOR RAIL TRANSIT NOISE CONTROL</title>
      <link>https://trid.trb.org/View/51935</link>
      <description><![CDATA[This paper describes a computer assisted methodology for planning rail system noise control.  Noise control usually involves several sequential stages of planning and design. At each stage, interactions with other design factors are clarified, the number of design options is usually reduced, and the level of detail is increased for analysis of costs and performance.  In contrast with highway planning, urban rail system planners and managers can control a very wide range of system design elements, e.g. both on vehicle and guideway.]]></description>

      <title>ENVIRONMENTAL NOISE ASSESSMENT OF RAILROAD ELECTRIFICATION</title>
      <link>https://trid.trb.org/View/51936</link>
      <description><![CDATA[Energy considerations are causing railroads, especially East Coast commuter lines, to reconsider electrification of main lines to replace or partially replace diesel-electric power. Among the secondary benefits, reduction in wayside noise is often cited as a significant environmental improvement.  The noise problem may be more complex than assumed at first glance.  Using a recently developed prediction model based on the highway noise computer model developed by the Transportation Research Center of the U.S. Department of Transportation, it is shown that wayside noise is strongly dependent on higher speeds attainable as a result of the track improvements associated with electrification .  The exhaust noise from the diesel electric locomotive is replaced by wheel/rail noise which can at higher speeds be a more significant noise source.  Replacement of the diesel-electric locomotives by high speed electric locomotives may show benefit only in that the new source is closer to the ground and as a result is subject to ground effects and shielding.]]></description>

      <title>ESTIMATION AND CONSIDERATION OF THE SHINKANSEN NOISE FOR A NEWLY-ESTABLISHED LINE (NEW TOHOKU LINE)</title>
      <link>https://trid.trb.org/View/51931</link>
      <description><![CDATA[The Japanese government has noise standards which must be met by Japanese National Railways, including the extensions of its high-speed Shin Kansen lines.  The control of noise and vibration from the passage of high-speed trains on elevated structures is described, along with methods of determining and measuring each source.]]></description>

      <title>DESIGNING A NATIONAL STUDY OF RAILWAY NOISE IN GREAT BRITAIN</title>
      <link>https://trid.trb.org/View/51932</link>
      <description><![CDATA[Phase I of a two-phase project to investigate railway noise in Great Britain is now in the data collection stage.  Two major problems, subjects of this paper, have been site selection procedure and noise measurement methodology. Using a statistically drawn sample, a map-based noise level prediction method and an efficient noise measurement strategy, it has been possible to simultaneously estimate the proportion of residences in such proximity to rail lines that they may be annoyed by train noise, test all reasonable hypotheses about the causes and correlations of railway noise annoyance, and derive a mathematical model of physical characteristics of railway noise annoyance.]]></description>

      <title>A TRAIN NOISE GUIDELINE FOR LONDON</title>
      <link>https://trid.trb.org/View/51933</link>
      <description><![CDATA[The possibility of a new high speed rail link from the, now defunct, Channel Tunnel to the centre of London highlighted the need for new guidelines to be used when assessing the environmental effects of railway noise.  Initially, only the question of compensation for noise was considered but, with acute pressure on building land in London, the need for a planning guideline becomes of equal or greater importance particularly in connection with the development of housing sites near existing railways.  This paper describes the development of a railway noise standard equivalent to the current practice for road traffic.  The social reaction to noise in France and Great Britain is shown to be equivalent by comparing road traffic noise social surveys.  A French railway noise survey is then used to establish any difference between average community reaction to road or rail noise.  Finally, American data is used to establish how the percentage population annoyed varies with noise level.]]></description>

      <title>STUDYING THE NOISE IMPACT OF A RAILROAD GRADE CROSSING ELIMINATION PROJECT</title>
      <link>https://trid.trb.org/View/51934</link>
      <description><![CDATA[A grade crossing elimination project for the Long Island Railroad will elevate tracks carrying 8 to 12-car electric commuter trains about 20 feet above the residential community of Massapequa Park, New York.  To assess the noise impact of the project--and to learn more about train noise and its measurement and analysis--the NYS Department of Transportation conducted an extensive study.  This paper summarizes what was learned.]]></description>
