In an open floor plan a garbage disposal is heard across the living area, so noise becomes a real concern, and nobody wants a loud grinding sound while guests are talking a few feet away. A quiet model uses extra sound insulation, a well-balanced motor and a mounting system that keeps vibration out of the sink, which keeps the sound from carrying.
The six disposals below are well-known models, chosen for their sound-conscious designs. We have not used these products ourselves, so confirm the motor power class, the mounting type and the dimensions on the current listing before you buy, and check that the unit fits under your sink with your plumbing. Pay attention to the sink flange, the drain angle and the space needed to reach the reset button, since a disposal that is hard to service gets neglected.

Quiet Garbage Disposal FAQ
How loud is a garbage disposal?
Noise varies by model and use. Premium units with extra insulation are noticeably calmer.
Does more horsepower mean more noise?
Not necessarily. A strong motor can run smoothly, and good insulation matters more than raw power.
Can I install it myself?
Many people can, but plumbing and wiring require care. Hire a pro if you are not comfortable.
What if the disposal jams?
Turn off the power and use the maker’s recommended steps, which often include a hex key reset.
