I found places with a silent surface for steps and lay them in the form of images (Attached Files).
Steps not heard on the sidewalks around the houses. Steps not heard on seceded ceramic tile. As well soundless lying doors. I think these surfaces should be done noisy. {F25744} {F25745} {F25746} {F25747} {F25748} {F25749} {F25750} {F25751} {F25752}
