Traffic Noise Barrier Estimation Tool

Quickly estimate traffic noise barrier requirements with Patching Associates’ Traffic Noise Barrier Estimation Tool

Patching Associates’ Traffic Noise Barrier Estimation Tool is a free, easy-to-use online tool that assesses noise barrier height and placement for transportation projects within municipalities. This tool provides municipal planners and developers with valuable information to inform project development. 

GETTING STARTED

If you know the specifics of your project, here’s what to gather before you get started:

  • Posted road speed limit (km/hr),
  • Ground surface,
  • Traffic Volume (Average Annual Daily Traffic (AADT)),
  • Heavy truck percentage,
  • Road Gradient,
  • Receiver distance from the middle of the intersection (m),
  • Receiver elevation height from ground (m), and
  • Source to Receiver distance.

If you need to meet a specific dB noise target, you can define your target Sound Pressure Level (SPL) at the receiver and the tool will calculate the required barrier height. Alternatively, you can instead select “vary barrier height” to specify a barrier height and find out the resulting SPL.

Please contact us or consult the Canada Mortgage and Housing Corporation (CMHC) Road and Rail Noise: Effects on Housing standard for more information surrounding any of the above parameters. Some important notes include:

  1. Traffic volume is to be provided as Average Annual Daily Traffic (AADT). Peak hour traffic volumes are typically considered to be 10% of the AADT.
  2. An acoustically “hard” surface is one that reflects sound well. This can include concrete, asphalt, clay, or compacted gravel. If more than half of the ground surface between the source and the receiver is hard, please select this option. Alternatively, if more than half the surface between the source and receiver is soft, such as grass and shrubbery, then please select the “soft” option.
  3. The distance of Receiver from intersection is to be measured in a straight line from the center of the nearest intersection to the receiver location.

This graphical tool allows you to change a number of geometric parameters to match a project scenario as closely as possible. To get started, please consider the following:

  1. There are several draggable elements in the graph that you can vary to change the relative geometry between the source (road) and the receiver. Adjusting these will automatically update your barrier results.
  2. In addition to the draggable elements, there are a number of user-defined parameters and target inputs.
  3. Hover over these different geometry and input items to see specific instructions or help text. You can toggle the visibility of help texts using “Show/Hide Help Tooltips” button.
  4. If you are not sure about what value to use for an input field, you can use the default value, which should give a reasonable approximation.

 

WHAT IS THE TRAFFIC NOISE BARRIER ESTIMATION TOOL?

Developed based on calculation methods obtained from the CMHC Road and Rail Noise: Effects on Housing standard, and designed to be used prior to starting a Noise Impact Assessment (NIA), The Traffic Noise Barrier Estimation Tool tool enables city planners and developers to quickly determine potential placement parameters and corresponding impacts of a noise barrier for each project. 

After determining that a noise barrier is required to meet project goals, a more detailed assessment may be required, including onsite measurements and modelling, to meet all applicable regulations. Noise regulations may also differ from those used within this estimation tool and may include more or less stringent standards. Patching Associates can help you navigate through these applicable regulatory requirements and options.

WHY USE PATCHING ASSOCIATES' TRAFFIC NOISE BARRIER ESTIMATION TOOL?

  • It’s completely free! No obligation to purchase any report.
  • The tool is intuitive and easy to use.
  • To get a quick picture of noise barrier impacts.
  • To find a starting point for your project’s noise requirements.
