How do I mute the annoying beeps before and after a Google voice search?

[edgeplot]

Galaxy Note 9, Android Pie, not rooted. Whenever I hit the microphone to do a voice search in the Google app or voice type in the keyboard, the phone makes a horrible beep before and after speaking. I can't figure out how to turn it off. I don't want to turn off all system sounds/volume since I want other sounds, just not this awful beep. I also don't want to root my phone. TYIA!

Not possible unless your phone's Media volume is set to Mute.
