Principle of setting up sound barriers to prevent electromagnetic radiation

Anti electromagnetic radiation sound barrier is an additional anti electromagnetic structure added to the sound barrier.

Advantages of Yuanxing's Anti Electromagnetic Radiation Sound Barrier

Pay attention to material selection:

Based on magnetic permeability and saturation performance, and referring to commonly used shielding materials (such as Mumetal containing 80% high permeability nickel alloy), through design experiments, select materials in the direction of ultra-low carbon steel (ULCS) when the field strength is sufficient to saturate the high permeability shielding body.

Institutional design guarantees:

The Yuanxing anti electromagnetic radiation sound barrier is mainly ensured by the mutual support of the sound-absorbing mechanism and the magnetic shielding mechanism.

Convenient and reasonable main structure:

In order to maintain a simple shape of the shielding body that can provide a low magnetic resistance path or a "low magnetic resistance path" for magnetic field movement, the anti electromagnetic radiation sound barrier of Yuanxing Group's rail transit line uses a structure with a tangent arc surface.

Performance indicators of electromagnetic radiation sound barrier

The anti electromagnetic radiation sound barrier can shield electromagnetic waves with frequencies below 200MHz by more than 90dB, which is a good anti electromagnetic radiation effect.
