Searching for a solution to your noisy blender? This DIY blender sound shield is just what you need!

Blenders can be loud. The more powerful the blender, the louder they tend to get.

This can be a problem in many situations. For example, getting up early and blending up a quick breakfast smoothie, only to rudely wake up anyone else in the house still sleeping.

Some blenders run quieter than others, but they can be either low-powered or quite expensive. Besides, you probably don’t want to have to replace a perfectly good blender just because it’s noisy. For the most part, even a moderately-powered blender is going to make some significant noise.

There is a solution to this noise problem, and that is blender sound enclosures.

You may have noticed that some commercial blenders, such as the ones used at Starbucks or Booster Juice, have these plastic sound enclosures that help mute some of the noise made by these powerful blenders.

You can, of course, simply purchase a quiet blender, or a blender with built-in soundproofing, but there are also many quick, easy, and affordable ways you can make whatever blender you are using at home, much quieter.

This post will go over how to make your own blender sound enclosure, as well as some additional tips on how to make blending quieter and how to soundproof your blender.

Let’s get into it!

How Can I Make My Blender Less Noisy?

There are many ways to help soundproof a noisy blender.

Before getting into how you can make your own sound shield, here are some simple tips you can try:

Put a towel over the blender.

Covering both the jug and motor base of the blender with a thick towel, will muffle the sound and help reduce any shaking of the jug, base, or lid while blending on high speeds.

Put a towel under the blender.

This will reduce shaking and prevent sound reverberating off the countertop. Similarly, you can put another soft material like a silicone mat, a cloth placemat, foam, cardboard, etc. underneath.

Blend in a non-echo-y room.

Sometimes location makes all the difference! Similarly, make sure your blender is not too close to a wall, or touching other appliances that the sound can reverberate off of.

Put your ingredients in the blender in the right order.

This technique mostly pertains to when blending things with multiple ingredients, such as smoothies.

Ingredients like ice, frozen fruits, nuts, and other hard ingredients, are the noisiest ingredients to blend. To reduce the noise, add ingredients from softest to hardest; soft ingredients and liquids should be added to the blender jug first, and the largest and hardest ingredients should be added last.

This will ensure that the blades of the blender are not initially smacking into hard ingredients and whipping them into the sides of the blender, hence making a ruckus. Instead, the blender has time to get through some softer ingredients first, and make a bit of a slushie to help muffle the chopping of the hard ingredients once they reach the blades.

Wear ear protection.

If it’s just for yourself that you want to reduce the noise, good old soundproof headphones or earmuffs should do the trick!

Buy a blender sound enclosure.

Many brands, like Vitamix, sell plastic sound enclosures for their blenders. There are also universal blender sound enclosures that you can purchase for any blender.

Make a blender sound enclosure.

Finally, instead of investing in a sound enclosure, or in a new blender, you can just DIY your own blender sound enclosure! It doesn’t take too much time, effort, or money to make your very own sound enclosure custom to your blender!

Here’s how to make one…

How to Make a DIY Blender Sound Shield

All you need to make this DIY blender sound shield is a few common materials and some time, patience, and tinkering!

Step 1: Measure your blender.

It is easiest to make an enclosure that covers both the jug and the base of your blender. Essentially, it will be a cube that you place over the entire blender when blending.

Measure from the surface the blender is sitting on, to the top of the lid on the jug, and add an inch. This is your height. Then measure the greatest width and depth of the blender and add an inch to each.

Depending on the size and shape of your blender jug and blender base, you may be able to make an enclosure that sits on the top of the blender base instead of the countertop. Many blenders with built-in sound enclosures are built like this. This will allow you to access the controls while blending. However, for this, the jug must be smaller in width and depth than the base so that it has something to sit on. Also, this may not reduce the sound as much as a full-sized enclosure.

Step 2: Select your material.

You want an insulating material for your sound shield.

There are a few different materials you can use for this blender sound enclosure: styrofoam, plexiglass, wood, cardboard, plastic, etc.

Something like cardboard will likely be too flimsy, so you will probably want to opt for something more study like wood or thick styrofoam.

Styrofoam is the easiest option to work with, and you don’t need any special tools to cut or attach it.

If you are comfortable working with wood or plexiglass, these are great options as well. Commercial blender sound shields are usually made of clear acrylic, which is nice because you can see through it. These types of materials will require familiarity with tools like drills and saws.

If you are not using foam, you will also want some foam tubing to place around the bottom where the cube is going to sit on the countertop. It might also be a good idea to line the inside with a soft foam or fabric material, just for some extra insulation and muffle.

Step 3: Cut out your panels.

You will need 5 separate panels – the 4 sides, plus the top.

Draw out the panels on your material, using your height, width, and depth measurements.

If using foam, you can cut out the panels using an exacto knife. If using a harder material, you may need to use a saw or other power tool.

Step 4: Assemble the panels together.

Here, the method of attachment of the panels to each other depends on the material you chose.

For styrofoam, the easiest option is packing tape/duct tape, or glue, or both.

For materials like wood or plexiglass, you will need to screw them together using a drill.

Optional: To allow for a door, only attach one side (top or left side) of the front panel. Attach it using a hinge of sorts – either tape (in the case of styrofoam) or an actual hinge from the hardware store (in the case of materials like wood).

Step 5: Finishing touches.

Optional: If you used a hard material like plastic or wood, you can line the bottom edges of the cube with soft foam to help it sit more snugly.

You can also add handles to the sides or the top of the cube to be able to pick it up easily.

You can even paint it and personalize it!

How it works:

This sound enclosure is very simple – it is basically an insulated cube that your pop over your blender when it is running, to muffle out the sound.

If you did not hinge the front panel as a door, simply turn on the blender, cover it with your enclosure, and remove the enclosure when you’re ready to turn off the blender. There may be some noise initially and at the end, while the enclosure is not covering the blender. There is also the limitation that you cannot adjust the speed while the blender is covered. You must lift the enclosure to adjust the speed or turn off the blender.

If the front panel is a door, this allows you to turn on/off and adjust the speed of the blender while it is running, without having to remove the entire enclosure.

This DIY blender sound shield works best when paired with the other soundproofing techniques such as a towel underneath.

I know this may sound ridiculous but is it possible to use a regular box insulate the entire box so it just fits loosely over my vita mix when in use?
