Default File Location on Android for Downloads

I use ES File Explorer on Android. When downloading files from Chrome, there are times I want to save them for later. This is the default location where Android puts them on my Moto X Pure.

storage/emulated/0/Download

How do I turn off the click sound when closing a tab in Chrome?
