in my opinion alot of resource packs that supposadly add old sounds either do too much with making some stuff that already have sounds such as furnaces and force them to be silent,or they only add the player hurt noise.
this resource pack has the player noise filthered so that the robotic background noise does not happen
only chests and ender chests have the old opening and closing sounds,so i didn't change the doors and trapdoor sounds as i think the new version sounds better with the veriety it brings
afcorse old fire and flint and steel sounds,walking and more are also added
in short i added only the sounds that in my opinion can fit well enough with the newer minecraft versions
