Accessibility - Background Sounds

[Selkie1776]

Please add the feature to have background sounds in the accessibility options.

1. It helps people who suffer from tinnitus.

2. It can help people concentrate.

3. It can help people relax.

A couple of basic white noise/pink noise types of sounds, for example: a waterfall, wood burning, crickets, bird chirping, wind, etc...

The background sounds could be played at the same time when a different audio source is working, like a music app or a video app.

Because the background sounds will be of the operating system and not a third party app - not only that the background sounds could be played simultaneously with other audio sources but also save more battery.
