This is the quietest disposal we have ever owned. Your sound level number was right on que. We have used you disposals for over 20 years. Our first one had to have the crusher blades replaced at close to 10 years because we were disposing orange, lemon, and grapefruit rinds from our orchard and their acid ruined the blades. It had a 10 year warranty and we called your service department at 9 plus years and you sent a repairman to our home and he rebuilt it. We used it another 9 years and then bought our new one. Thanks
