Abstract
ABSTRACT
Evaluating the acoustic properties of noise reducing devices is an important prerequisite for
efficient noise protection along major transport routes. For determining the insulation
properties of noise barriers in situ, the so-called Adrienne method has been introduced in the
European Technical Specification CEN/TS 1793-5. In autumn 2009, acoustic measurements
were performed by AIT to investigate the influence of different measurement equipment, in
particular two amplifier/loudspeaker systems, on the obtained insulation properties of the
noise barriers. The device under test was an aluminum noise barrier with a flat surface. In this
paper it is shown that, although significant differences in the frequency spectra of the
measurements exist, the third octave band results and the single-number ratings described in
the Technical Specification provide comparable results.
