Question about "free" sound FX.

Hello people, where can i check if a sound FX is free to use in my games, because i saw in some sites that the popular Roblox death sound is free to use for everyone, except if you claims it is your creation, so, can i use it specifying that i dont own it?, thanks and sorry if this is the wrong section to ask this.

Maybe check on Even Hollywood movies use sounds from thereā€¦

Thanks, i will check it!
