Screening becomes less effective at reducing the noise at lower frequencies, this is because it is less directional and diffuses easily travelling around a barriers edges.If effective, the noise can be considered as coming from the installation surface. KEMET recommends, in that case, to use the sensor VS-JV10A, chassis insulation type.

Statistical sound levels give more details about the dynamics of the environmental sound. L AN is defined as the level that is exceeded N% of the observation time. The most popular statistical levels are L A90 and L A95 for characterizing the always present ambient noise and L A10 for characterizing the louder part of the observation time. L A10 has been …

 · Results indicated that synthetic screens were less effective in noise abatement when compared to tree belts of sparse to medium and dense planting but they were still able to significantly reduce noise levels and provided relief from noise pollution when compared against a scenario with no screening at all.
