The pedestrian ground net in the anechoic room is a structure designed to facilitate the safe walking of workers in the anechoic room. It usually has the following requirements:

Sound absorption performance: Although the main function of the pedestrian floor net is not to absorb sound, it may need to have a certain sound absorption capacity in some cases to reduce the impact on the acoustic environment. For example, it might use steel wire mesh or specially designed mesh materials that can withstand the pressure of people walking and equipment moving while trying not to reflect sound.

Stability and load-bearing: The pedestrian floor network must have sufficient strength and stability to bear the weight of the staff and the test samples or other tools and equipment they may carry, and will not deform, collapse or generate additional vibrations during long-term use. noise.

Low reflectivity: Since a fully anechoic room requires no obvious reflection on the six surfaces (including the ground), the design of the floor grid should try to avoid the formation of hard reflective surfaces. Its surface and structure should help absorb or scatter sound waves, thereby maintaining The indoor sound field is uniform.

Anti-slip and safety: The ground net material must ensure non-slip when walking and prevent accidental falls; it must also comply with relevant safety standards, such as setting up protective railings, warning signs, etc. to ensure the safety of operators.

Height and connection: The height of the floor grid is generally designed to be slightly higher than the sharp sound-absorbing structure in the anechoic room to ensure that it will not come into contact with the sharp edges. At the same time, consideration must be given to matching the elevation of the door opening and being flush with the work channel. To facilitate barrier-free access.

Flexibility and maintainability: The design of the floor grid should also take into account the convenience of installation and disassembly, as well as the need for future cleaning, maintenance and facility upgrades.

Vibration isolation effect: In a high-precision test environment, the pedestrian ground grid also needs to have a certain vibration isolation function. The ground grid is isolated from the foundation of the anechoic chamber through a spring isolator or similar device to prevent external vibrations from being transmitted through the ground grid. The inside of the anechoic chamber affects the measurement results.
