    • Pavement Characteristics Affecting The Frequency Content Of Tire/Pavement Noise 

      Öngel, Aybike; Harvey, John (Inst Noise Control Engineering, Iowa State Univ, College Engineering, 212 Marston Hall, Ames, Ia 50011-2152 Usa, 2010-11)
      Tire/pavement noise is a major contributor to traffic noise at highway speeds. Annoyance is more closely related to frequency content than to overall A-weighted noise levels, therefore spectral content analysis of tire/pavement ...
    • Prediction of Lifetime for Different Asphalt Concrete Mixes 

      Öngel, Aybike; Harvey, John (Taylor & Francis Ltd, 4 Park Square, Milton Park, Abingdon Ox14 4Rn, Oxon, England, 2012)
      The California Department of Transportation has been using open-graded mixes to reduce traffic noise levels and to improve wet weather safety. There is a need to identify how long open-graded mixes last in terms of ...
    • Principal Components Regression of Onboard Sound Intensity Levels 

      Öngel, Aybike; Kohler, Erwin; Harvey, John (ASCE-AMER SOC CIVIL ENGINEERS, 1801 ALEXANDER BELL DR, RESTON, VA 20191-4400 USA, 2008-11)
      Roadways paved with open graded asphalt mixes typically generate lower traffic noise levels as compared to other types of pavements. A program was initiated in 2005 in California to evaluate the effectiveness of noise ...
