In this comprehensive guide, we will explore various methods and tips to help you reduce the noise and make your kitchen a quieter and more enjoyable space.

From simple adjustments to advanced soundproofing techniques, we’ve got you covered!

How To Reduce Mixer Grinder Noise

Why are Mixer Grinders Noisy?

Before we delve into the solutions, it’s essential to understand the science behind the noise produced by mixer grinders.

The primary reasons for their loudness include:

High Operating Speeds

Mixer grinders are designed to operate at insanely high speeds, averaging around 20,000 RPM (Rotations Per Minute).

This rapid rotation is necessary to process ingredients quickly and efficiently.

However, this high-speed operation puts extra strain on the motor, leading to increased noise levels.

Noisy Ingredients

Pulsing hard ingredients like peppercorns or spices inside the plastic container generates considerable movement and vibration.

As the ingredients bounce around vigorously, they create additional noise.

Brushed Motors

Many mixer grinders utilize brushed motors due to their cost-effectiveness.

A brushed motor contains fixed magnets and a rotating electromagnet.

To achieve a complete rotation, the polarity of the fixed magnets must be flipped, and this is done through carbon brushes.

This rapid flipping of magnet polarity contributes to the noise during operation.

Low-Quality Components

To keep the overall cost low and cater to a wide customer base, some manufacturers use low-quality materials and bearings in their mixer grinders.

These inexpensive components tend to produce more noise during usage.

How To Reduce Mixer Grinder Noise

Now that we’ve identified the reasons behind the loudness, let’s explore practical and effective methods to reduce mixer grinder noise:

Method 1: Keeping it Away from the Wall

One simple yet effective approach involves keeping the mixer grinder away from walls.

When the mixer grinder is placed adjacent to the walls, sound waves bounce off the surface and amplify the noise.

However, when we moved it to the center of the kitchen countertop, approximately 25 cm away from the wall, we noticed a slight reduction in noise levels.

While this method does work to some extent, the difference may not be significant enough for those seeking substantial noise reduction.

Method 2: Placing Mixer Grinder on a Thick Mat

Another approach involves placing the mixer grinder on a thick mat to absorb some of the noise and reduce overall loudness.

We tested this method by using a thick cotton mat, approximately a foot away from the wall, and observed a minor reduction in noise levels.

Similar to the previous method, while it did show some improvement, it may not offer a substantial noise reduction for users looking for a more peaceful kitchen experience.

Method 3: Using Acoustic Foam

Among the methods we tested, using acoustic foam emerged as the most effective solution.

However, it comes with a cautionary note. When using acoustic foam, it’s essential to avoid blocking ventilation underneath the motor housing.

Properly chosen acoustic foam with flatter options allows us to place the mixer grinder on it comfortably, resulting in a reduction of noise levels by about 7-8 dB.

Placing acoustic foam on the adjacent wall further decreased the noise to approximately 83 dB, showing promising results.

Is Acoustic Foam Enough?

While acoustic foam proved to be effective in reducing noise levels, its practicality for day-to-day use requires consideration.

Blocking ventilation may lead to motor damage, and handling the foam during regular use might not be convenient.

Additionally, noise bouncing off the wall adjacent to the mixer grinder still remains a concern.

While acoustic foam helps in absorbing sound waves, a comprehensive solution may require multiple layers of soundproofing.

Advanced Soundproofing Techniques

For users seeking a more comprehensive approach to reducing mixer grinder noise, advanced soundproofing techniques can be considered:

Sound Enclosure Boxes

Sound enclosure boxes are designed to contain and reduce noise levels. Building a sound enclosure box for your mixer grinder can significantly reduce noise pollution in the kitchen.

It involves using materials like MDF, mass loaded vinyl, and acoustic foam to create a box around the mixer grinder.

However, keep in mind that the box may need proper ventilation to prevent overheating of the motor.

Soundproofing Kitchen Doors

If you don’t have the option of moving your mixer grinder away from the wall (e.g., in apartments), consider applying acoustic foam to kitchen doors.

This can help reduce noise leakage from the kitchen and contain the noise within the room.

Investing in a Less Noisy Mixer Grinder

While soundproofing methods can help, investing in the best silent mixer grinder is often the most straightforward and effective solution.

High-end models with brushless motors and sharp blades are generally quieter than their cheaper counterparts.

Opting for a quality mixer grinder can significantly reduce noise levels and provide a quieter cooking experience.


Reducing mixer grinder noise can be a challenging task, but with the right methods, it is possible to achieve a more peaceful kitchen environment.

While keeping the mixer grinder away from walls and using thick mats may result in minor noise reduction, using acoustic foam has shown to be the most effective solution.

However, its practicality for daily use may vary for different users.

Advanced soundproofing techniques, such as sound enclosure boxes, can provide a more comprehensive approach, but they may require careful consideration to maintain proper ventilation.

Remember, finding a completely silent solution for mixer grinders may be a challenge, but by implementing a combination of the tested methods and advanced soundproofing techniques, you can significantly minimize noise and enjoy a more pleasant cooking experience in your kitchen.

Consider your specific needs and preferences when choosing the most suitable method to reduce mixer grinder noise. Happy cooking!
