| Abstract: | According to the acoustic capability test data of the whi stles adopted by main locomotives in China and related UIC references,the acoust ic parameters of locomotive whistles used in railway noise EIA is identified pri marily,which include octave band sound pressure level and directivity parameter. These parameters can be used in noise prediction calculating in EIAs of railway construction project. |
