ELI5: why is the "s" sound more predominant when people speak quietly?

also happens when the volume of a tv is low for example, i can only hear "ss s s... s... s s... s s s s... s"

It's called "sibilance", it's just a property of sound and how humans form speech. There is a class of sounds made forcing air with the tongue, against the teeth. In English it's the class of sounds like "**s**illy" "**z**one" "**sh**ip" and **"G**enre". 

These sounds are just naturally louder than the rest of speech and due how recording technology works, they are artificially amplified in microphones and speakers.
