Road traffic noise reducing devices - Test method for determining the acoustic performance - Part 5: Intrinsic characteristics - In situ values of sound reflection under direct sound field conditions

This European Standard describes a test method for measuring a quantity representative of the intrinsic characteristics of sound reflection from road noise reducing devices: the reflection index.
The test method is intended for the following applications:
- determination of the intrinsic characteristics of sound reflection of noise reducing devices to be installed along roads, to be measured either on typical installations alongside roads or on a relevant sample section;
- determination of the in situ intrinsic characteristics of sound reflection of noise reducing devices in actual use;
- comparison of design specifications with actual performance data after the completion of the construction work;
- verification of the long-term performance of noise reducing devices (with a repeated application of the method).
The test method is not intended for the following applications:
- determination of the intrinsic characteristics of sound reflection of noise reducing devices to be installed in reverberant conditions, e.g. inside tunnels or deep trenches.
Results are expressed as a function of frequency, in one-third octave bands between 100 Hz and 5 kHz. If it is not possible to get valid measurements results over the whole frequency range indicated, the results shall be given in a restricted frequency range and the reasons of the restriction(s) shall be clearly reported.

Protihrupne ovire za cestni promet - Preskusna metoda za ugotavljanje akustičnih lastnosti - 5. del: Bistvene lastnosti - Terenske vrednosti odboja zvoka z uporabo usmerjenega zvočnega polja

Ta dokument opisuje preskusno metodo za merjenje količine, ki predstavlja bistvene lastnosti na področju odboja zvoka od protihrupnih ovir za cestni promet: indeks odboja.
Preskusna metoda je namenjena:
– ugotavljanju bistvenih lastnosti na področju odboja zvoka od obcestnih protihrupnih ovir, ki se merijo na običajnih mestih namestitve ob cesti ali na ustreznem vzorčnem delu;
– ugotavljanju bistvenih lastnosti na področju odboja zvoka od protihrupnih ovir med dejansko uporabo na mestu uporabe;
– primerjavi specifikacij zasnove s podatki o dejanskih lastnostih po koncu izgradnje;
– preverjanje dolgoročnih lastnosti protihrupnih ovir (z večkratno izvedbo metode).
Preskusna metoda ni namenjena:
– ugotavljanju bistvenih lastnostih za odboj zvoka od protihrupnih naprav za namestitev v odmevnih pogojih, npr. v predorih.
Rezultati so izraženi kot funkcija frekvence v tretjinskih oktavnih pasovih med 100 Hz in 5 kHz. Če ni mogoče dobiti veljavnih rezultatov meritev za celo opredeljeno frekvenčno območje, se rezultati navedejo za omejeno frekvenčno območje, razlogi za omejitev območja pa se jasno opredelijo.
