Why Are Blenders So Loud? (6 Reasons & Tips)

Why Are Blenders So Loud? (Reasons & Tips)

If you have worked in the kitchen, you will be familiar with different kitchen appliances. Without it, it is hard to cook a meal quickly. These appliances make our lives easy by saving time and energy.

However, some of them are annoyingly loud and hard to use. One such appliance is a blender. Most people know that blenders are loud. It becomes irritable when you have to blend several things. Using a loud blender causes unnecessary noise in the kitchen.

Some lenders have noise-canceling features, but they are expensive. They also do not function as well as the traditional, noisy blenders.

why Are Blenders so loud

Blenders are loud because of the presence of steel blades, blender motor, high speed of the motor, usage of cheap materials and plastics, and presence of old & rusty parts.

We will discuss each of the points in detail.

1. Steel Blades

Most blenders, if not all, have steel blades. Steel is an excellent material for making blender blades, but it is also very abrasive. The back and forth motion of these blades resemble the grinding process.

It crushes everything inside your blender, including the motor. It is the reason why blenders make a loud noise. High-quality steel is durable and rust-resistant. If your blender makes too much noise, it indicates low-grade steel. 

2. Blender Motor

The motor pulley needs the power to grind anything in the blender. It makes the blender spin. 50-100 RPMs is the speed for most blenders. High-quality blenders can reach 250 RPMs or more.

Electric motors require a lot of energy to function. The age-old belt and pulley system is a common mechanism in blenders. These mechanical parts use electromagnets to make the blades spin fast enough to grind anything.

Without a strong electromagnet, it is impossible to run a blender. Strong electromagnets deliver better performance and vice versa. However, a strong electromagnet also creates much noise. It is why high-quality lenders are usually the noisiest. 

3. High-speed

Irrespective of the dish, a blender will always run at high speed. Anything running at high speed will make a lot of noise. Most blenders have multiple speed settings, and the noise increases with each one.

You will have the motor running at high speeds for a few minutes no matter what you cook. The blades use much power to chop the hard materials into a fine powder.

The speed of the motor and the force of the blade together create many sounds. It is nearly impossible to eliminate the sound. However, you can reduce it using a thick cloth.

4. Necessary High RPM Count

A high RPM count ensures that even the hard materials turn into powder within seconds. A low RPM does not generate the speed or force required to crack hard materials. It is why every blender needs to have a high RPM count even at the lowest setting.

However high RPM count also consumes more power, causing the motor to heat up. The increased pressure on the machine and heat create a loud sound. If anything has a high RPM count, it will consume more electricity and make more noise.

The best way to quiet down a blender is to cover it with something that blocks noise. High-quality commercial-grade blenders come with a noise-canceling cover, making the environment quiet. 

5. Cheap Materials and Manufacture

Blenders are tools that make the cooking process easy. They have several mechanisms working simultaneously to produce the result. Something will inevitably go wrong in a machine as complex and compact as a blender.

Unfortunately, most manufacturers use cheap materials to make their blenders. They also cut corners in manufacturing costs creating a poor quality product. Low-quality blenders are quick to heat up, due to which they make much noise.

Cheap plastic and metal are nondurable and make much noise. Sach blenders usually cost below $30. Fortunately, you can get a high-quality blender that does not emit unnecessary noise if you are willing to spend some money. 

6. Old and Rusty Parts

A rusty material is never a good sign for the blender or any machine. Low-quality steel catches rust surprisingly quickly.

Moreover, people grind many things in the blender. Sometimes particles of food get stuck between the gaps of the blender causing the metal to catch rust.

If any one part of your blender gets damaged, it will significantly increase the noise. One can avoid this issue by keeping the blenders clean and dry after every use. However, low-grade material will eventually catch rust. 

How to make your blender quiet?

1. Put a towel under the blender

Everyone has extra towels or pieces of fabric in the house. Put a fluffy towel or folded cloth under the blender to reduce noise.

Hard surfaces like granite increase the sound coming from the blender. A thick towel dampens the sound by becoming a barrier between the blender and the hard surface.

3. Use a sound enclosure box

A sound enclosure box blocks the noise from reaching your ears. It does not stop the blender from making any noise but acts as a barrier around it.

You can build a sound enclosure box using wood and some sound-absorbing foam. Always leave one side open to operate the blender.

Combine these two methods

Use a sound enclosure box and a fluffy towel to reduce maximum noise. A combination of methods is always better than a one-way solution.

The thick towel will dampen the sound, while the box will block any existing noises.

Is it natural for blenders to be loud?

It is natural for blenders to create some noise. It is because multiple mechanisms are working simultaneously. Anything that moves fast in a circular motion creates much noise, like the blades of a blender.

Things getting crushed and chopped rapidly will naturally make the process noisy. One can tolerate this noise because it does not get unnecessarily loud. 

However, some cheaply made blenders are unbearably loud. It is partially because of their materials and low manufacturing costs. They lack many modern innovations introduced to reduce the noise in a blender.

Here are a few blender models that are quieter than others.
