All of our disposers feature the exclusive  Torque Master Grinding System with its balanced turntable and armature that help keep noise and vibration to a minimum, however, it can become really noisy if something gets in there to cause a ruckus. With the disposer unplugged, grab a flashlight and take a look down the drain and see if you notice anything that can be causing the noise. Plastic or metal items are usually the culprits.
