This highly informative piece will go through 11 simple steps to help you get the loud generator quiet. Let’s find out!

Box it Up – Soundproof generator box

One intelligent choice is to box the generator up in a way that the noise remains within it. The idea of a soundproof box mostly goes with the usual large-scale standby whole house generators. Because the box makes it more substantial, and you won’t be able to move it as freely either.

Get a wooden box from a retail shop that closely matches your generator size. Next, you’d have to cut out ventilation holes for the generator. Remember, generators usually heat high quickly. And without proper ventilation, you risk burning the generator.

We recommend you use a vent duct, and the more of these you add, the better it can reduce the heat.

Then insulate the box efficiently with Styrofoam and glue it down with unique Styrofoam adhesive, which you can collect from the nearest convenient store.

For further and soundproofing, you can get two rolls of Dynamat from Walmart and put it over the already placed Styrofoam. Do the same with the box lid as well and drill in holes precisely to get the wire in or out. You can add hinges on the lid for trouble-free access every time.

Finally, seal in the edges with green glue.

There you go! You now have your soundproof generator box!

Increasing Muffler Size

Mufflers are one of those tools which are used to reduce the noise level. It is a high possibility that your generator may already have a muffler installed. If that is the case and you’re still getting louder sounds, you should go for a bigger one.

Getting a super quiet generator muffler may not seem as active as you’re thinking right now. But it can surely play it’s part while you’re combining it with other noise reduction measures.

Sound Deflectors Can be Effective

Another effective way you can achieve a lower sound level is by installing sound deflectors. Given that the generator is kept in a small and enclosed space like a shed or outhouse, you can go for it anytime.

Sound deflectors are not there to soundproof the generator; rather, they will block and diver the noise frequency, so it doesn’t reach you. This can be quite practical while combining with the other methods mentioned.

Rubberizing the Feet

Vibration during run time is another major cause behind generator buzzing. A portion of sound pollution can be prevented once it reduces the vibration level significantly.

So, to get the shaking in check, you can attach rubber on generator feet it will decrease the noise by keeping it firmly attached to the ground.

Changing the Exhaust Direction

It is another simple and easy technique you may use. As we mentioned earlier, one of the primary sources of this buzzing is the exhaust. And if it is faced towards your living space, the waves will definitely follow it, making your sleep a nightmare.

But you can just make the exhaust facing otherwise. It will divert the wave towards different directions and give you lesser problems.

Generator distance from house

Always try to set up the generator at least 20 feet away from your living room. The further away it is, the more the possibility of you and your family having a sound sleep and a healthy day-to-day life.

Check if it’s Broken

Is your generator producing noise to a level that you feel is unusual? Then, maybe your generator is broken or has some mechanical issues inside. It can be a reason your generator is unusually loud.

We suggest you get it serviced, and the chances are that you’d find issues inside. Upon fixing them, it should perform as it used to and give you at least a lesser noise.

Measure Power Consumption Rate

Power consumption can be another reason behind noise build-up. If you’re irritated by your generator’s increased sound, you should check the power it is consuming.

Try to reduce the power to the point that it can still function. And this should lower the constant buzzing that has been bothering you.

Get the Exhaust in the Water

There are plenty of things you can do to lower down those decibels. One of them is getting the water muffler for the heavy generator. Find a 5-gallon bucket and fill it up with water. Now, connect one end of a hosepipe to the exhaust and let the other end dip in the water.

It dampens out the extra decibels, lowering the high noise level down.

Digging A Hole

This is another technique mostly used in the military. First, measure your generator and dig a 5-6 ft hole in your backyard. Now, put the generator inside that hole. Try putting cellulose bags over it to block the sound from coming out. We know cellulose to have a texture that works to deflect sound. This can also significantly lower the noise usually produced by generators.

But this particular technique may backfire when/if it is raining. The hole is certainly not fit to tackle water, and it will flood damaging your generator and rendering it useless.

So, we recommend you use caution while performing this technique.

The Simple Cardboard Method

This simple technique lowers 10 decibels with no hassle. Just take unused plywood sheets and make them stand against the generator. Try rotating the plywood and see which position works best at deflecting sound. You will easily find the right combination that’d lower at least 10 decibels.

Unlike the box mechanism, the air can easily pass through, and it does not overheat the generator. You don’t have to worry about insulation, ventilation, or other such issues with this approach.

To Sum Up

We have discussed many ways as to how to make your generator quiet as a cricket. Each of these strategies can reduce the noise to a certain point. But if you can combine all the techniques and apply them smartly, there is a strong possibility that you’d have a power generator with the least noise.

So, follow these simple steps and enjoy the clean and quiet electricity!
