Are you constructing a new pass-by noise test track, rehabilitating an existing track, or need your ISO test track certified? The measurement is conducted in-situ, without the need for extracting core samples and the associated patching repairs.
Transtec provides acceptance testing of new noise test tracks, and periodic checking of existing tracks at intervals required by the standard. The shape, flatness, and sound absorption properties of the track affect how the sound propagates away from the vehicle.

Such an instrument utilizes the two-microphone method for sound absorption. The basic properties of the surface remain unchanged. If the document is revised or amended, you will be notified by email.

ISO Tracks: Specifications
Characteristics of a test track can significantly influence the exterior vehicle noise measurement. Furthermore, DIN ISO recommends a non-destructive test method for periodical checking of the surface characteristics. Our ISO conformance test services are capable of measuring them all, including macrotexture MPD using the profile method and sound absorption coefficient using the impedance tube method.
For surface texture, ISO Please first log in with a verified email before subscribing iwo alerts. Add to Alert PDF. What Is Pavement Texture?
Conformity testing to both the new ISO Irregularity measurement of pavement courses: In particular, pavement surface texture affects the noise generated by the tires. When you evaluate ISO for conformance, the following test standards are used.
In addition, the skid resistance properties of the surface and its mechanical impedance may influence measured noise levels.
The purpose 1084 the ISO standard is to specify the noise test track in a manner that minimizes the variation of vehicle noise measurements made at different testing locations. If you are an automotive company, a tire company, or a test track owner and you are involved with vehicle exterior noise measurements, then you must know about standard ISO What Is Pavement Noise?
In addition, the variability of properties is reduced.
The latest version of ISO for pass-by noise test tracks has many requirements, some of which can be confusing. How do I explain to my construction contractor to deliver a pavement with sound absorption coefficient less than eight percent?

ISO 10844 Noise Test Tracks Services
108844 The standard is a revised version of ISO Quiet Concrete Pavements in Belgium: We can also assist in design and specifications for new or rehabilitated pass-by noise tracks and minimize your risk of not conforming to the ISO standard. Characteristics of a test track can significantly influence the exterior vehicle noise measurement. We have no amendments or corrections for this standard.

In order to minimize the variation in rolling sound emission and vehicle sound oso measurements made at different testing locations it is, therefore, necessary to describe exactly the relevant surface properties and specify carefully the properties of the materials, design and construction of the test surface.
