Abstract:

The main parameters for acoustics evaluating of sound barriers and their relations are briefly introduced in this paper. The methods for testing of acoustic properties of sound barriers are summarized. The data of testing is analyzed. It provides a reference for research and development of railway sound barriers.

Key words: acoustics, sound barriers, weighted sound isolation, noise reduction coefficient, testing
