The acoustic slabs consist of one or more underground slabs that are sensitive to micro-variations in pressure. This allows the slabs to detect footsteps with greater precision. A built in timer system prevents over-counting of pedestrians who step twice on the slabs. 

 

The modular design of the acoustic slabs allows for greater flexibility and adaptability in installation on trails with varying widths. Up to eight slabs can be connected to a single counting system. For wide passages, the dimensions and spacing of the slabs can count people walking alongside each other, while maintaining an accuracy of ± 5%.
