My student couldn't hear the high notes on my piano and I couldn't hear her sing high- Solved

I was concerned that I would have to find another way to give singing lessons to my student who is 9 hours away because she was not able to hear the higher notes on the piano when doing vocal warmups with me and I couldn't hear her sing the high notes or most notes very well even after she purchased a microphone. And at one point there was an echo.  I am happy to say issues were solved quite quickly when I changed my audio settings and had her do the same.  Here's what worked perfectly for us:

Zoom background noise removal is on

Background noise suppression is low

Advanced Echo cancellation is aggressive

May this be helpful to others who have endured the same issues 🙂
