How To Make A Silencer For A Generator – Useful DIY Project

Besides power outages, it is so hectic to have these loud generator noises disturbing everyone around.

So, in this article, you learn the generator noise reduction method. Are you tired of those noises and want a quick solution to them?

If yes, your noisy generator requires a silencer to make it quiet and give you some peace.

But do you know how to make a generator quiet?

It won’t be wrong to say that you can easily DIY a silencer of your own, just by working a while longer with woodwork and brainstorming to develop a generator silencer that will muffle those unbinding noises within seconds of operation.

To make it easy for you, we came up with a handy guide that has the easiest way to develop a silencer without the need to have extra time spent on developing a method. 

Let’s start with your silencer by saying bye to those hectic sounds!

How To Make A Silencer For A Generator?

Dealing with generator noise can be tricky, but thanks to silencers that muffle unnecessary noise.

To have your silencer, you need first to measure the dimensions of your generator.

Measurements are meant for constructing a silencer compatible with the size of your generator.

Once you know what dimensions your generators have, go for a wooden frame and use a high-quality insulator that will not allow the noise out of the wooden frame.

To know the stepwise detail procedure, stay till the end!

What Is Silencer For Generator? 

A silencer is a handy accessory that is either a premade device that you can purchase or construct one of your own using wood and insulators to muffle the noise generated by the heavy-duty generator.

The silencer performs the same function as a muffler to reduce the noise and emissions from the exhaust unit when the generator operates. 

During operation, the generator converts mechanical energy into electrical energy.

Whatever process deals with mechanical energy will also generate noise; you might require a silencer to keep your unit running smoothly without causing disturbance to anyone residing around the generator site.

Parts Of Generator Involved In Noise Generation:

During combustion and energy generation, powering your electrical devices and home appliances involves a generator whose certain parts are responsible for generating noises.

For instance, you might observe sounds forged from the radiator fan, exhaust, engine, and structure-related noises.

All these noises increase the level of sound that is usually unavoidable by most users and leads to disturbances for anyone residing around. 

These core parts are involved in noise generation that needs to be damped to have a quiet generator without compromising the unit’s power supply.

A large generator mostly produces these loud sounds.

If you have a small portable generator, you don’t require a DIY generator muffler silencer kit or silencers because they are already Ultra-quiet designed devices.

Step Wise Procedure For Making Silencer:

Despite various methods involved in constructing a silencer, including devices that are only core parts specific and reduce each part’s noise, you can also go for an overall low-noise device by building an acoustic silencer for enclosing your generator, damping all the noise with the help of a high-quality insulator made in contact with wooden frame.

Follow the stepwise procedure for making a generator quieter silencer enclosure or box to eliminate all the loud noises previously causing disturbances.

Ensure you get all tools and requirements, and let’s get on board to DIY a silencer of your own.

Requirements:

• Measuring tape 
• Notebook and pen 
• Wood 
• Insulating material sheets
• Hammer and nails 
• Other DIY tools

Procedure:

Get To Know Your Unit Dimensions:

Before constructing a silencer box for a generator, all you need is to measure the dimensions of your generator along with extra space for your generator to fit in.

Remember that your generator must be size compatible with the wooden box so that you can easily put on the noisy generator in muffle mode. 

Any mistake in taking the dimensions will result in a silencer box that would be either too small for a generator or too big to muffle the sound.

Go for exact dimensions, leaving the desired pre-measured additional space for incorporating insulation and the generator. 

Constructing The Wooden Box And Frame:

Using these dimensions, you can construct a desired and compatible box for your generator that will act as a silencer later.

Make sure you make a small handle that will cause ease for carrying the silencer. You can go for adding wheels to the wooden box to ensure ease of portability. 

When constructing the wooden box, take wood and cut four wood pieces compatible with the side measurements of the generator.

With the help of tools like hammers and nails, combine the sides, resulting in a box structure.

Incorporate the wooden frame to impart strength and stability.

The wooden box will be the base for adding insulation, resulting in a silencer box.

Try Not To Suffocate The Unit:

When constructing a silencer box, leaving spaces for ventilation is important, as the generator produces toxic exhaust gases that must not accumulate in the silencer box.

You might be well aware that those fumes might contain carbon monoxide, which is hazardous to health. 

For active ventilation, construct one opening on the top of a silencer and the second one opposite the first in the silencer box.

In this way, those toxic fumes will timely evacuate from the silencer box and keep the generator safe and Ultra-quiet. 

Insulate The Wooden Box:

Once you have constructed the wooden box, you must add strong, high-quality insulation that will be responsible for muffling the sound.

The insulation will eliminate the medium for sound waves; the sound won’t get out of the box and won’t create any disturbances. 

What do you think kind of insulation would fit for the silencer box? We suggest opting for strong, high-quality, thick rubber sheets as an insulating material for a DIY project.

Other insulation may include plywood with foam or vinyl material that will be reducing generator noise.

Note that insulation is added either of multiple types or a single material with multiple layers to reduce generator noise.

TIP:

 An important fact that you must keep in mind is that it is in between some insulation; you have to leave a certain space; the reason behind that is that the sound will get entry and will be easily absorbed without letting them go out from the silencer box.

Testing The Silencer:

Once the silencer is ready, you can check its functioning by placing it on the generator and keeping the generator in running mode.

Compare the noise levels; if the noise is reduced, you are done constructing the functional silencer.

Importance Of Silencer For Generator: 

Now that you know how to quiet a generator, it’s time to understand what benefits will be gained by working on a silencer project for noisy generators.

Consider the beneficial aspects of silencers and go for one to make your noisy days get into quiet ones. 

Eliminating Noise:

The presence of a silencer will absorb all the unnecessary noise without letting them go out and disturb you.

We know those heavy-duty generators are much noisy that does require a muffler, so incorporate one to have peaceful power outages while keeping your house and devices on efficient backup power mode.

Provide Safety To Your Unit:

Additional coverage on your unit protects it from harsh environmental conditions and weather effects.

The silencer provides extra safety with a reduction in noise up to a lower decibel level. 

Enhance Portability:

Incorporating a handle or tires at the corner of the silencer can make it easily portable and be carried along with your generator to any place you want to run the unit.

These wooden silencer boxes will make no hassle while transporting them.

You can even carry the generator while it is placed in the silencer box; the wheels will do their job effectively in this case. 

Eliminate Toxic Exhaust Gas Accumulation:

Using silencer boxes with active ventilation will eliminate the chance of toxic fume accumulation, keeping the site safe from deadly carbon monoxide.

So DIY out your own using the standard materials and let your generator reside in a safe and free-from-gas silencer box, converting your hectic, noisy surrounding into peaceful, quiet surroundings.
