Published By Publication Date Number of Pages
SNZ 2010-04-30 136
]]> Sets out procedures and requirements for the prediction, measurement, and assessment of road traffic noise for new and substantially altered state highways and local roads. The Standard is intended to be used primarily by local authorities and road controlling authorities and seeks to promote quicker and consistent decision-making nationally regarding the management of road traffic noise. It also provides best practice guidance and advice on methods for mitigating reverse sensitivity situations and the environmental effects of noise exposure on nearby noise-sensitive activities. For the purpose of this Standard, where any project includes a mixture of new and upgraded existing roads the roading authority shall determine the relevant criteria to be applied to each section of the road for traffic noise mitigation.

Published By Publication Date Number of Pages
JIS 2013-02-20 51
]]> This Standard specifies the essential characteristics of a test surface intended to be used for measuring vehicle and tyre/road noise emissions.

The surface design given in this Standard:

– produces consistent levels of tyre/road sound emission under a wide range of operating conditions including those appropriate to vehicle sound testing;

– minimizes inter-site variation;

– provides minor absorption of the vehicle sound sources;

– is consistent with road-building practice.

NOTE 1 For the purposes of this Standard, the terms noise and sound are used interchangeably.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 10844: 2011 Acoustics-Specification of test tracks for measuring noise emitted by road vehicles and their tyres (lDT)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.

Published By Publication Date Number of Pages
ISO 2017-03 22
]]> ISO/TS 13471-1:2017 specifies procedures for determining the effect of temperature on tyre/road noise emission. Temperatures considered are tyre, road and ambient air temperatures.

The noise emission for which this document is applicable is measured by means of ISO 11819-2, or similar methods such as the on-board sound intensity (OBSI) method specified in Reference [1]. Measurement results obtained at a certain temperature, which may vary over a wide range, are normalized to a designated reference temperature (20 °C) using a correction procedure specified in this document.

Published By Publication Date Number of Pages
ISO 2008-05 42
]]> ISO/TS 13473-4:2008 describes the methods that are available to perform a spectral analysis of pavement surface profile signals. It specifies three possible methods for spatial frequency analysis (or texture wavelength analysis) of two-dimensional surface profiles that describe the pavement roughness amplitude as a function of the distance along a straight or curved trajectory over the pavement. The result of the frequency analysis will be a spatial frequency (or texture wavelength) spectrum in constant-percentage bandwidth bands of octave or one-third-octave bandwidth.

ISO/TS 13473-4:2008 offers three alternative methods to obtain these spectra: 1) analogue constant-percentage bandwidth filtering; 2) digital constant-percentage bandwidth filtering; 3) constant narrow bandwidth frequency analysis by means of Discrete Fourier Transform, followed by a transformation of the narrow-band spectrum to an octave- or one-third-octave-band spectrum.

The objective of ISO/TS 13473-4:2008 is to standardize the spectral characterization of pavement surface profiles. This objective is pursued by providing a detailed description of the analysis methods and related requirements for those who are involved in pavement characterization, but are not familiar with general principles of frequency analysis of random signals. These methods and requirements are generally applicable to all types of random signals.

Published By Publication Date Number of Pages
ISO 2017-03 26
]]> ISO/TS 11819-3:2017 specifies two tyres intended to serve as reference tyres when using the close-proximity (CPX) method specified in ISO 11819-2.

The CPX method is a method for evaluating different road surfaces with respect to their influence on traffic noise, under conditions when tyre/road noise dominates. This method ideally requires the use of standardized tyres, which have noise characteristics that are broadly representative of the effect of road surfaces on the noise emission of passenger car and heavy vehicle tyres. However, such tyres are not specified in ISO 11819-2. This document serves to specify these standardized tyres.
