Most of us would not have considered the noise level when we bought a mixer grinder, but now you understand. Well, you learn from experience and know that you aren’t the first one to make this mistake.
There are specific ways we can reduce the noise produced by the mixer grinder. Most of which are things that we can do ourselves, i.e., no professional help is required.
In this article, we will discuss why the mixer grinder is loud and a few solutions to reduce the noise level.
What Makes The Mixer Grinder Noisy?
While running the mixer grinder, have you ever thought, “Is there any way to make this silent?” If you have, don’t worry because you are not the only one. Here are some of the most common causes for your mixer grinder to produce noise.
For the mixer grinder to work efficiently and to have a greater speed performance, it needs to have a powerful motor. The noise produced is due to the working of the motors. The motor has fixed magnets and rotating electromagnets.
Since the electromagnets can only rotate at 180 degrees, the fixed magnets have to flip for the motor to complete one rotation (360 degrees). When this happens at a quicker pace, the appliance gets noisy.
How do you check the speed of a mixer grinder? To know how fast the mixer grinder blade can rotate, check the RPM (revolution per minute).
A good mixer grinder rotates at a speed between 18000 to 23000 RPM. It can only run at this speed if the mixer grinder has a powerful motor. But when it runs at this speed, a lot of noise is produced.
The whole appliance vibrates when the motors rotate at high speed to grind the ingredients, especially the hard ones. This, as such, does not create much noise. The mixer grinder becomes noisy when the sound waves caused by the vibration are reflected on the hard surface it is placed on.
Have you tried hard ingredients like peppercorn, nutmeg, ginger, sugar, or cinnamon? If you have, you would know how noisy this can be. When we turn on the mixer grinder, these hard ingredients sit against one another and the walls of the grinder, making loud noises.
Do note that the noise level varies based on the material of the mixer grinder jar. A plastic jar would make less noise than a steel mixer grinder jar.
Remember how motors had to rotate for the grinder to function? Well, these rotational movements are possible using either a brushed model or a brushless model.
Most companies use the brushless model because they are cheaper than the brushed model. But the problem with the brushed model is that the carbon brushes used to flip the magnets make a lot of noise while rotating at high speed.
Some manufactures use very little metal to make the different components of a mixer grinder; instead, they substitute it with cheap plastic material. It is profitable for them because they do not have to spend a lot of money manufacturing it, and when the appliance breaks, we will automatically buy a new one.
This is why it is crucial to invest in a good quality mixer grinder. Even though it might be costlier than the cheap products, it will benefit us in the long run.
How To Reduce The Noise Level Of A Mixer Grinder?
I hope you got a better understanding of the various reasons why the grinder makes so much noise. Now, we can discuss ways to reduce the noise level of a mixer grinder. Some of the most common methods are listed below.
1. Use A Dampening Mat
Placing the mixer grinder on a sound dampening mat is one of the tested out and the most effective ways to reduce the noise produced by the grinder. As mentioned above, one of the causes is vibration.
So, when we place the grinder on a sound dampening mat or any anti-vibration mat, the vibration does not pass onto the hard surface, neither does the mat itself vibrate. Hence, we can eliminate this noise to an expend. Sound deadening mat, silicone craft mat, and mass-loaded vinyl are three dampening mats that we can use.
2. Attach Some Rubber Feet
This is almost similar to the dampening mat. The only difference is that rubber feet are attached to the feet of the mixer grinder while the dampening mat is not connected. Also, it is cheaper than a dampening mat.
You can stick four rubber feet or grommets under your grinder to reduce the noise caused by the vibration of the appliance. You can attach the rubber grommets with green glue. Green glue also helps to reduce the noise transmission since it acts as an acoustic noise-dampening caulk.
Most of the modern and good-quality mixer grinders come with rubber feet. So, while purchasing, consider buying one with rubber feet to control the noise level in the atmosphere.
3. Move The Mixer Grinder Away From The Wall
The vibrating sound waves reflect onto the hard surface on which the grinder is placed. Just like this, the noise made by the grinder reflects onto any hard surface surrounding the mixer grinder.
The smoother the hard surface, the better it is at reflecting the sound. That is, a grinder placed in a corner will make more noise than one set away from any walls.
So, your solution for this is to simply move the appliance away from any rigid, plain, and smooth surfaces while you use it.
4. Hang Soft Material On The Wall
This can be taken in connection with the point mentioned above. Sound reflects more on hard surfaces than soft ones. So, if we place soft clothes on the wall, the reflecting surface is changed.
This can reduce the noise level to an extent. The thicker the cloth material, the more effective it is in absorbing the noise.
5. Soundproof Your Kitchen (Doors And Windows)
Soundproofing the whole kitchen can be a bit expensive. So, I would suggest that you try acoustic management.
For example, if you don’t want to have clothes hanging everywhere in the kitchen, you can substitute the clothes with acoustic foams.
These forms are good absorbers of sound waves and reduce reverberation. It won’t block the sound transmission, but it will certainly reduce the noise level. Also, these forms are not very expensive, so you can definitely afford them.
6. Soundproof Enclosure Or Box
Other than the dampening mat and the rubber grommets, this is another effective way to reduce the noise level in the atmosphere.
The best part about a soundproof enclosure is that we can build it at home if the ones found in the store are expensive.
Materials needed for DIY soundproof enclosure –
- Mass loaded vinyl
- Acoustic foam
- Green glue (preferably, but any strong glue would suffice)
- Measure your mixer grinder. (L*B*H)
- While cutting the material, add a few more inches to the measurement of the grinder.
- Glue the three sides to the bottom piece. After this, glue the top to one of the sides.
- Start lining the interior; the first layer is the mass-loaded vinyl. Use Green glue to seal the edges.
- Place the acoustic foam on top of the first layer.
- Drill a small hole in the power cable.
The mixer grinder will be quieter than usual. However, the downside to this is that you will not be able to see what happens when you switch on the grinder. Also, the appliance will heat up because it does not escape in the enclosed area.
7. Use It At The Right Time
Using the mixer grinder at odd times will make it noisier. It is almost similar to trying to sneak in food at night; everything we try to open will make noise.
When using your mixer grinding, avoid using it early in the morning, late at night, or during nap hours in the afternoon, i.e., avoid using it when it is too quiet.
Also, it does not bother people as much as it would when they are sleeping.
8. Buy A Quiet Mixer Grinder
This is the best thing you can do if your grinder is damaged and you search for a new one. If you buy a quieter mixer grinder, you will have the freedom to use it according to your convenience without bothering anyone.
A few mixer grinders have in-built insulation, which helps to block the motor noise. Also, choose grinders with a brushless motor and a thick and good quality material around the motor to reduce the noise.
Another thing you can look for in a quiet grinder is the sharpness of the blades. The sharper it is, the quicker the grinding is complete, and less the noise produced.

Most of the mixer grinders available in the market produce a lot of noise while running. However, there are a few quiet ones, but you need to look at its features to understand if it is a quiet one or not.
If you cannot find a quiet mixer grinder, you can reduce the noise level with the help of dampening mats, rubber feet, acoustic foams, soundproof boxes, etc.
