Ring Doorbell Outside Sound on Motion

Everytime someone walks by, my doorbell makes a noise on the outside. I would like to turn this off but I can't figure it out.I still want to record motion but I don't need it to make any noise.In fact, I have it hooked up to my traditional door bell so absolutely no sound needs to come from the doorbell itself (except if I'm talking through it).Please help. I have everything dialed in except this.
