Noise is the most common complaint about garbage disposals, especially in open-plan kitchens. No disposal is silent, but some makers add sound insulation and design the motor to run more quietly. The listings below mention ultra-quiet motors; we have not measured sound ourselves, so treat the claims as the maker’s words.
The six disposals below include four KRAUS WasteGuard models and two InSinkErator units. Details come from the product listings. Check dimensions, mounting and wiring notes on the product page.

What Affects Noise
| Factor | Effect |
|---|---|
| Sound insulation | Extra padding around the motor can dull noise |
| Motor size | A bigger motor grinds with less strain on tough scraps |
| Mounting | A good mount reduces vibration through the sink |

Tips to Reduce Noise

- Avoid bones and hard pits, which are loud and hard on blades.
- Check the mounting ring and sink connection for loose parts.
- Add sink insulation if the sink bowl amplifies noise.
Mistakes to Avoid
- Assuming a larger motor means a quieter unit.
- Skipping sound insulation notes in the listing.
- Grinding hard items.
- Ignoring a rattling sound, which can mean a loose part.
Quiet Disposal FAQ
Are quiet disposals really quiet?
They can be quieter than basic models, but all disposals make noise. We have not measured them.
Does horsepower affect noise?
Not directly. Insulation and design matter more.
Do I need a plumber?
If you are not confident, yes. A loose install can add noise.
