Noise

• 2015 Traffic Noise Practitioners Summit: This event brought together noise practitioners from 38 states throughout the country, as well as staff from AASHTO and FHWA, to discuss emerging topics of interest in the field and define a roadmap for the future of noise programs and research.
• AASHTO Products:
  • Standard Practice for Procedures for Measuring Highway Noise
  • Standard Method of Test for Measurement of Tire/Pavement Noise Using the On-Board Sound Intensity (OBSI) Method
  • Standard Method of Test for Determining the Influence of Road Surfaces on Vehicle Noise Using the Statistical Isolated Pass-By (SIP)
  • Standard Method of Test for Determining the Influence of Road Surfaces on Traffic Noise Using the Continuous-Flow Traffic Time-Integrated Method (CTIM)
