How do I change the volume of the jump sound?

I have been looking literally everywhere for a solution to the problem. I am trying to change the volume of the jump sound. For example, lets say this is the line of code for the jump sound.

["rbxasset://sounds/action_jump.mp3"] = "rbxassetid://409647180";

What would I have to type afterwords so that I can set the jump volume to a value of 2?

You don't need to use that, you could just use this:

local plr = game.Players.LocalPlayer.Character
plr.Head.Jumping.Volume = 2

To change the sound:

plr.Head.Jumping.SoundId = --put id here

If this somehow doesn't work. Please comment. If it does, upvote and accept answer. Thank you!
