Two people will be about 3 dB higher, four people would be 6, eight people would increase the level by 9 dB, sixteen would be 12 dB higher and so on.

This is only the case if they’re making identical sounds in phase with each other. The real life scenario of people walking would not scale in this way as there are too many variables. No two footsteps are the same no matter how hard you try.
