How to Soundproof a Workshop – 7 Proven Ways (2020)

how to soundproof a workshop

Noise pollution is a rapidly growing ignored problem. So, me and my uncle recently thought to soundproof his workshop and it really worked for us. Therefore, I am going to share with you all the possible ways to soundproof a workshop effectively. 

We came across many different methods of soundproofing a workshop. Here, I am going to share some of the most efficient and easy methods.

However, when any room, garage, or workshop is made soundproof, all that it needs is precision and accuracy.

Whenever there is some negligence, it can put all the effort in vain. I made a list of some methods to soundproof a workshop.

However, it all depends on your situation and needs to follow which method.

Why do you need to Soundproof a Workshop?

First of all, it is necessary to know what compels you to soundproof your workshop, and for that, I will draw your attention to the needs of soundproofing a workshop. This will convince you regarding the necessity of soundproofing a workshop.

However, in the later text we will know about some methods to reduce noise in workshops and how can you soundproof your workshop.

So, give this article a full-length reading in order to explore new ways of soundproofing a workshop.

Work without irritating your neighbors

Neighbors are like a second family. Their rights can never be ignored. Therefore, it should be kept in mind that the sound produced in your garage or workshop can disturb your neighbors.

It can even make them restless. Whenever, the workshop is not soundproof, it can annoy your neighbors first.

Use Heavy Machinery

Workshop is a place equipped with heavy machinery, hammers, saws, drills, etc. All these can bother not only your neighbors but also your family members if your workshop is closer or in attachment to your home.

Therefore, you need a shelter of soundproofed workshop to fight all these conditions.

Work with privacy

Your workshop is your private zone. Here you explore a new world by giving experimental form to your ideas and imagination.

However, an idea can enter any time to your head. Many times, you ignore these expensive ideas fearing the disturbance of people living around you.

Therefore, you need the magic of soundproof workshop to work freely and independently in your private workshop.

Nobody to bother you

Most of the time it happens that you hear complaints like; please don’t make noise! I can’t study or sleep! , your noise is bothering the baby! etc.

Soundproofing your workshop is a therapy for all such ills. You can say a big no to all such complaints and carry on with your work without any interference.

How to soundproof a Workshop?

If you have a home workshop in the basement or garage, it may be necessary to reduce noise through soundproofing.  You can soundproof a workshop by following certain techniques and steps to get it done in a most effective manner.

Soundproofing gives those inside your house and your neighbors comfort while you are working with your power tools like your diamond blade saw. It may also be needed to adhere to your area’s local safety laws and regulations.

Engineers measure sound in decibels or dB. The lower dB, the quieter the sound. Most of your power tools will churn out 85 to 100 dB of sound when you are using them.

It is the same as a noisy manufacturing plant. However, If you are looking for a cost-effective and viable solution that can help you reduce noise from your workshop, here are some methods;

Method 1; Acoustic noise panels to soundproof a workshop

Acoustic panels provide the perfect sound absorption materials for deadening and dampening sound in restaurants, offices and many more places. But you can also use them in the worships for dampening the sound.

They are composed of compressed mineral wool or foam.

The vibration caused by these panels converts the energy and thus dissipates it. Soundproofing panels can block noise from entering or exiting a workshop.

Each soundproof panel is heavy and dense, ensuring long-lasting quality.

Method 2; Insert a DRYWALL

I personally feel installing a drywall requires an expert. It is one of the efficient methods for soundproofing your workshop.

Drywall insertion requires skill and labor which makes it a little more expensive as compared to other methods. However, before inserting drywall cracks and holes in the workshop’s wall must be filled precisely.

Method 3; Use Mass Loaded Vinyl

Mass loaded vinyle for soundproofing a workshop

The tough task of soundproofing a workshop is made very easy with Mass Loaded Vinyl.

MLV is the perfect material for use as a sound barrier to workshop ceilings. It is a thin but super dense rubberlike material. Moreover, its flexibility and heaviness make it work great for all soundproofing applications.

Besides, it is best to be used instead of Lead materials for soundproofing. And is great for blocking frequencies from 4000 Hz all the way down to 125 Hz.

And these frequencies are what we can expect from the workshop machines to produce.

Method 4; Get Mineral Glass Wool

mineral wool

Glass wool is made up of fibers of glass arranged into a texture of wool. Glass wool batts can help to reduce the transmission of sound, especially between walls of the workshop.

However, their low density allows for more sound to travel through than heavier forms of insulation. For soundproofing a workshop, I will recommend glass wool with higher-rated batts.

Method 5; Moving blankets for workshop windows

A soundproof blanket is made from sound-absorbing materials that can absorb and block sound from going outside the workshop.

They are usually made of multiple layers of fabric. However, depending on the type, its efficiency ranges from 30% to 80% of blocking noise.

I will recommend using these blankets for workshop windows to make then soundproof because they have sound-reflecting ability.

Method 6; Remove the glass from the workshop windows

To reduce sound, you must create a barrier between the sound and ear that captures the sound. Buildings do that with walls, roofs, and windows that block sound waves from entering the room. To increase a window’s ability to block sound, you must :

1. Add mass; make the glass thicker and remove the single glass.

2. Add air space i.e increase the distance between window panes.

3. Insert a laminated glass; a glass-plastic-glass sandwich that reduces noise transmission.

Method 7; Fiberglass panels for workshop doors

fiber glass panels

The doors of the workshop can be made soundproof by using a fiberglass panel seal. These fiberglass panels trap the sound waves and stop them from going out or coming in.

Moreover, sealing the doors with such panels can add a significant effect in soundproofing your workshop.

Method 8; Rubber Mats for floor

Rubber mats are not only a good sound absorbers but also anti-fatigue and are easy to clean. Whenever you want to soundproof your workshop, rubber mats are such an important thing that cannot be ignored.

Heavyweight machinery causes much noise. The rubber of the mats acts as a noise reducer in this case.

Method 9; Sealing off the workshop

Cracks and gaps of doors, walls, roofs, and windows are an obvious reason for making your work a noise for the others.

Therefore, proper sealing of the workshop is required. I suggest using different plastic or rubber sealing strips which can stop the sound of your machines from going out.

So, if you are up with the task of soundproofing your workshop, take a start from the basics and seal off your workshop properly for efficient soundproofing.

Method 10; Build a small room within a workshop

Building a small room within a room seems much like a fun task. But hang on, it can really be a viable method for soundproofing your workshop. You can try DIYS, in this case, to make it cheaper and exciting for you.

This method is very effective for reducing the sound transmission during heavy mechanical work. For instance, you can think of making a small room for:

  • Metal cutting
  • Welding
  • Machines that produce more sound

About 80% of the sound will be blocked by the walls of this room, and you can block the remaining 20% by applying soundproofing materials on the other structures of the workshop.

This is an easy and amazing method of soundproofing your workshop, which my uncle has embraced also.

Here is a quick link for you to learn more about soundproofing a workshop along with the materials you may want to use.

How can I Soundproof my Garage Workshop?

You can soundproof a garage workshop by following these simple steps:

  • Find the source of sound leakage from the garage
  • Get soundproofing materials
  • Apply them in a correct manner
  • Get your garage soundproofed

Some people prefer to have a small workshop within their garages. However, it can be a cause of noise pollution for their family and neighbors.

In my case, I am fond of spending time with tools and repairing things. Therefore, I wanted to soundproof my garage workshop. It is the only way through which I could play my part in reducing noise pollution and of course improve the social relations.

So, if you are wanting to soundproof your garage too then you need to join me and read these important points. However, there are a few things to consider, but I will guide you through the important points.

Things you need to know before you soundproof a workshop within a garage

First of all we need to consider the main physics behind different sounds.

  1. Airborne Sound (voices, music etc.); It can only be blocked by mass.
  2. When sound hits a surface it turns to vibration energy that transfers through solid materials and surfaces with ease. For a high standard of soundproofing, we need to adopt the “Room within a room” technique.
  3. Soundproofing is like making the water to stay in a bowl without any leakage – To contain the sound within your garage, you need to soundproof all the walls, ceiling and floor. All the crevices of windows, doors, and air vents need to be filled and sealed, as sound can get through any left gap.

Let’s discuss about “ROOM WITHIN A ROOM TECHNIQUE”

For reducing noise we need to build a ” room within a room ” i.e a room within the garage.

The inner room is isolated from the outer room. We do this by using different systems. Besides, these systems are fixed with the solid wall and ceiling joists So, we can then build new wall and ceiling layers.

These systems act like shock absorbers, so when sound hits the new wall layers, it turns into a vibration energy, the system absorbs this energy stopping it from transferring into the structure.

Moreover, high mass materials such as “mass loaded vinyl” need to be added on solid walls, stud walls, and garage doors.

This technique is helpful in reducing the noise and making your garage an open place for you to work independently.

Steps to soundproof a workshop within a garage

In order to simplify it for you, I am going to explain soundproofing a garage workshop in the form of steps. These steps will help you to start from “A” and finish on “Z” means; you will not be left with any lacuna.

Step 1; Locate the source of sound

First, you need to locate the source of sound. There are multiples machines, tools, and other stuff in the garage workshop.

Therefore, it is very important to locate the basic source of sound and its transmission. Sounds can be because of machines, tools, etc. But the question is “what makes it more louder and easily transmissible?”

Well, this needs a keen observation of the garage. Once you locate the source of sound then it will be easy for you to soundproof your garage workshop.

Step 2; Use soundproofing materials

After locating the sources of sound transmission you can use different soundproofing materials to make your workshop soundproof.

Specification of different soundproofing materials for different areas of your workshop is given as under;


Installing a solid core door to decrease sound transfer is one of the best ways to soundproof your doors. Moreover, they seal gaps between jambs and the wall. Afterward, seal gaps between the door and jambs, and floor.

The following are some products I suggest using to improve door soundproofing:

Soundproofing Rubber

A self-adhesive backed rubber strip for soundproofing that fills sound leaking gaps in door frames. You can easily purchase it in different sizes.

Backer Rod

It is a soft, pliable, and water-resistant poly foam that is used to fill the gaps. It is available in different lengths.

Green Glue Noise proofing Sealant

It is used to fill gaps and cracks that noise could penetrate. It gives a vibrational break in the path of the sound.

Weatherstripping Tape

D-type gap blocker foam weatherstripping and soundproof neoprene foam rubber tape are amazing for decreasing sound movements between doors and jamb.

Suptikes Door Draft Stopper

It is a flexible 2 x 39 inches self-adhering silicone weatherstrip that attaches to the bottom edge of the door. Also, it contains three independent layers that work together to block sound movement through doors.

Draft Guard Energy Saving Under Door Draft Stopper

The Draft Stopper consists of two foam tubes which are wrapped in microfiber. Moreover, it blocks the sound to travel through doors. These stoppers are available in adjustable sizes.

Customizable Soundproofing Door Sweep

A metal rail attached to a rubber filled loop that seals the air gap between the floor and the door. The rubber gets compresses against the floor if it is uneven.

Acoustic Thresholds

A threshold with a smooth surface should be used with doors to make them soundproof. It must be higher than the carpet and wide enough to sit under the door.

Automatic door bottoms

They are used to make doors soundproof by adjusting its bottom to floor mats.

Soundproof Door Cover Blanket

Doors are usually covered with such blankets thus lowering the sound.

Multilayered Soundproofing Curtains

They are used to cover doors and windows, thus making them soundproof.

Mass Loaded Vinyl

You can also use MLV to soundproof garage workshop doors due to their thickness and higher density.


Inserting a drywall can also reduce the sound transfer through workshop doors.s

I am sure you would like to see more of these soundproofing materials. Just click here to see how has compiled a list of some of the best soundproofing materials of all time.


Sound can pass through poorly insulated ceilings of your garage workshop. You can soundproof them by using materials like; Mass loaded vinyl, glass wool, insulation bars etc.


If the walls of your garage are not properly made soundproof, they can become a trouble-maker. Inserting a drywall and using acoustic noise panels insulation can be helpful in this case.


Filling up the hollow floors and using floor mats can reduce the noise produced in garage workshops.

Step 3; Block the Air ducts

soundproof air ducts

Air ducts or air vents can also be a cause of noises coming from your garage. There are a number of methods to block these vents.

Here, I have given some top ways to block your air ducts;

1. Create A Sound Maze Inside Your Vent.

2. Use Acoustic Foam.

3. Fill The Vent With A Sealant.

4. Block Your Vents.

5. Cover The Vent.

Step 4; Oil the old machinery.

Sometimes the minute tasks that we ignore, put us in big trouble. Oiling the old machinery in your garage is one such task.

Moreover, old rusted parts of the machines produce friction which is a cause of irritating noise. So, oiling these parts from time to time is an easy and cheap source of getting rid of that noise.

This surely adds much to the soundproofing task of your garage workshop.

Techniques to soundproof a workshop of garage

After discussing steps lets give a glimpse of the techniques of soundproofing. Knowing about steps and materials without the technique to use them is like “a tea with no sugar”. So, let’s add sugar to this tea.

methods of sound proofing

There are four main methods to soundproof a space. They include adding mass, damping, decoupling, absorption.

Mass or Density. It is the easiest way to soundproof a space. This makes the space dense. More density means less sound waves absorption by that space.

Damping. It means the reduction of resonance(vibrations) in a room through reflection and diffusion. In simple words, it implies” to dissipate sound waves and vibrations”, before they get a chance to build up sound.

Decoupling. As we know, sound waves are no more than vibrational energy. This means that sound conduction occurs in a direct pathway. Decoupling the path can stop the conduction of these sound waves.

Absorption. Air cavities can resonate sound.  Trapped air results in producing sound waves, resonating in the object.

What is the cost to soundproof a workshop?

It can cost you up to $800 to soundproof a workshop. It all depends on the quality and number of materials that are used in the process of soundproofing.

So, for presenting you with a clear picture, I am sharing the prices of different materials used for soundproofing floor, ceiling, and windows of a workshop.

Professional fees for soundproofing a workshop

You can easily soundproof your workshop by doing all these activities by yourself but still, if you don’t have time to put the efforts in it then you can hire a professional to get it done for you.

  • A Local tradesman can charge around $50 per day for a two-man team depending on the intensity of work.
  • Whereas a professional soundproofing installer can charge around $200 per day for a two-man team.


Well let’s see what we have covered in this article. We started all the way by discussing the needs to soundproof our workshop. We validated our need by giving four basic reasons.

Then we discussed about ten methods which are used to reduce noise in a workshop. After that I shared steps of soundproofing my garage workshop and we added sugar to it by discussing methods of soundproofing.

In addition, I have also discussed the costs of soundproofing with you.

Now the question arises which method is best and do we really need to soundproof our workshops?

My view is “yes”, considering the need to reduce environmental pollution we cannot neglect noise pollution. As far as the best method is considered my opinion is “soundproofing needs to be considered at the very time of construction your house, workshop, garage, etc.

Room within a room is also a workable technology that can effectively make your workshop soundproof. It is an affordable and workable method of soundproofing.

The sound waves that are produced in the inner room are less audible in the outer area because of the other bigger which contains the lower workshop or garage.

However there are many DIY and cheaper methods of soundproofing for those who cannot afford the cost of expensive material.
