Microphone icon inside WiFi icon?

[rp33]

I've noticed that sometimes there will be what looks like a microphone showing up inside the WiFi signal icon next time o the clock. Sometimes I see just the top half, and sometimes the bottom, but mostly the full icon...shaded in black right inside the WiFi icon. I sometimes see it if I've just spoken out loud. I don't have Google now on, or hot word detection either. Has anyone else noticed this, or know what it is? I know it sounds crazy.

They're two triangles upside down and right side up.
They indicate when there is download and upload activity.

Dang. I guess I am going blind. It's pretty small, and looked like the mic icon to me. Ha. Thanks!

Funny... that's what I thought of at first too!
