Option to Disable Ambient Background Sound

I can't believe how many threads concern Meta's refusal to provide  customisation options, as though denying users the  capacity to do so is part of Antichrist v2.0's mission statement for his company, but anyway, here's another.

Can we please have the option of disabling that horrible ringing noise?

It's not pleasant, it doesn't add anything to the experience, it's like New Age tinnitus.

Now that we finally have the option to disable that ghastly mirror, how about the same option to disable the dreadful ringing noise?
