EXCELLENT NOISE REDUCTION
As people can feel differences of sound changes in range 2-3 dB we are sensing twice as much noise, when the increase reaches 8-10dB. Soundim noise barrier is designed to reduce the noise at least to half, especially high frequencies which are considered to be the most disturbing. The total noise reduction depends on factors like train speed, track conditions and type of train.
Noise absorption 13 dBA (Class A4), EN 1793 2, EN 1793 3.
Noise insulation 30 dBA (Class B3), EN 1793 2, EN 1793 3.
Total noise reduction up to 12 dBA, SFS-EN ISO 3095.
