Research highlights ► The paper uses the close proximity method to assess the instantaneous tyre/road sound pressure levels of vehicles in Hong Kong. ► A “tyre/road noise versus vehicle motion” profile provides an easy way to estimate the instantaneous tyre/road noise level. ► We find that the noise level is minimum at cruising mode and increases with acceleration/deceleration rates.
Abstract Based on the close proximity method specified in draft ISO/CD 11819-2, the instantaneous tyre/road sound pressure levels of eighteen road sections constructed with the same pavement surfacing materials are recorded and analyzed. A “tyre/road noise versus vehicle motion” profile, presented by a 3-D plot of the tyre/road noise against the instantaneous acceleration/speed, provides an easy way to estimate the instantaneous tyre/road noise level.
