• Example 1

It is mandatory that a standard test track as specified in ISO 10844 (JIS D 8301) is used for measuring noise emitted by road vehicles. The test method for in situ measurement of the sound absorption coefficient is specified by ISO 13472-2:2010. The model 9303 is a measurement system that complies with these requirements. Simply placing the acoustic duct on the track surface, the sound absorption coefficient can be measured quickly, making the system optimal for measurements during construction of the test track, as well as for aging measurements.
