Best Sellers:

Quiet garbage disposals should feature a metal mount and insulation to minimize vibrations.

A common consumer complaint about their garbage disposals is that the machine makes a lot of noise during use. On average a garbage disposal makes 80 dB of noise when it grinds up your food scraps, which is less noise than a food blender. The noise complaint is so common because noise levels are often forgotten or deemed not important due to lack of information on it during the research phase of buying a food waste disposer. However, many users end up finding this characteristic (noise level) extremely important once the machine is installed and used. So, if you are someone that gets annoyed by noisy kitchen appliances or even woken up by your children or partner turning on something like a vacuum cleaner or blender in the mornings, then we recommend purchasing a sound-proof garbage disposal.

What makes a garbage disposal quiet?

So why is it that some disposals are noisier than others? The main source of avoidable noise that a disposal produces are vibrations. There are serval characteristics of a garbage disposal that contribute the noise level that it produces while in use, these include:

  • mount material
  • build quality
  • insulation technology
  • continuous vs batched feed
  • and the power of the motor.

When sound is a concern, consider a waste disposal with sound seal technology.

Mount material

During research for one of our blog posts (Waste King vs InSinkErator) we found that the material of the mount, attaching the disposal to your sink, also effects the amount of noise produced due to vibrations.


If the quietness of a garbage disposal is a deciding factor for you, we strongly recommend a disposal with a metal 3-bolt mounting system, and NOT one with a plastic EZ mount. The metal mount are much more solid and durable, which allows for less vibrations and therefore less noise, however it is also important that disposal is installed properly as installation can also be the cause of any extra vibrations.

Although build quality and the material of the mount are important factors in the amount of noise your disposal makes, there are also other accessories for garbage disposals, beside an EZ mount which may help muffle the noise, such as a sink baffle.

Build quality

The build material used to construct the body and motor of the disposal plays an important role in how much noise a disposal makes. High quality materials tend to be sturdier and will therefore vibrate less than flimsy poor-quality plastics. Therefore, if you want a quiet disposal, we recommend investing a little more in a higher-end disposal, such as those in the InSinkErator’s Evolution line which is mostly made of metal instead of plastic.

Insulation technology

Whether your disposal features insulation technology or not has huge influence on how much noise the disposal produces. Manufacturers name this insulation technology SoundSeal or SoundShield, these insulation shields block most of the noise produced during use, however they also make the machine heavier and larger.

Therefore, you need to have enough space in your kitchen cabinet to install a sound-proofed garbage disposal. If you have enough space under your sink and you find it important to have a silent operating disposal then we strongly encourage you to choose a disposal with sound insulation technology.

Continuous vs batched feed

Whether you have a batched or continuous feed disposal can also make a difference in the noise level. Although the difference will likely not be substantial the batch feed disposals are quieter, because you actually place a clog over the opening to the motor while the disposal is in use, which prevents noise escaping from your kitchen sink drain.


Power of motor

The power of the disposal’s motor also plays a role in the level of noise the disposal produces during operation. Typically, a low-powered motor creates less noise. However we found that most high-powered disposal feature sound insulation to compensate for the extra noise, while low-powered ones do not. This leaves low-powered disposals with being insignificantly more noisy than high-powered disposals. Nevertheless, low-powered disposals still have the advantage of costing less, weighing less, and are usually taking up less space too. Meaning that they are ideal for households that want a quiet and budget-friendly disposal or have a kitchen with limited cabinet space.

Noise level comparison

Like we said in our introduction, the average garbage disposal, that is not sound insulated, generates around 80 decibels of noise during usage. The amount of noise a disposal makes while in use really depends on the type of disposal and whether or not the machine contains sound insulation. A soundproof garbage disposal lowers the noise level drastically, it can cut the amount of decibels even in half.

Noise source and decibel level

  • Whispering – 20 dB
  • Bird calls – 40 dB
  • Garbage disposal (insulated) – 45 dB
  • Office sounds – 60 dB
  • Garbage disposal – 80 dB
  • Dishwasher – 80 dB
  • Food blender – 90 dB
  • Lawn mower (powered) – 100 dB
  • Chain saw – 120 dB


This is what people say about silent garbage disposals

We have selected a few reasons why people like their quiet operating food waste disposer.

  • “I couldn’t hear my InSinkErator as it is so quiet.”
  • “I can barely hear the disposal over the running water.”
  • “I love it for being unbelievable quiet and its vibration-free operation.”
  • “Much more quiet than our old unit. The first time I was not even sure if it was working.”
  • “My disposal is whisper quiet, except when it is chewing up bones.”
  • “Our InSinkErator Evolution Excel is worth the expense when you want a quiet disposal.”

So, is a quiet garbage disposal the right choice for you?

Overall, if having a quiet garbage disposal is important to you and your family, which is reasonable, you will need to make a choice between investing more money into the disposal or sacrificing on power and quality. With a high-end quiet disposal, you will also gain in durability and power, but you run the risk of your sink and cabinet not being able to support your disposals weight or size. While, with a low-powered quiet disposal you keep the benefit of low weight and small size but sacrifice power, leaving you with the constant question of “can my disposal handle this type of food waste?”. This choice is up to you to decide.
