How to Make Your Generator Quiet as a Cricket

Generators are useful machines to power your house during power shortages. But, a generator that makes an ear-deafening noise is unacceptable. Don’t worry if you have purchased the generator that produces intolerable noises. This article will turn the tables for your noisy generators.  

Adding to your information, the noise ordinances are increasingly imposing fines above  $500 per offense within the property boundary. If your generator is louder than 65 or 55 decibels either in daytime or nighttime you can’t escape from the fine. This must be threatening to your mental peace. Before knowing to make your generator quiet as cricket we need to figure out the reasons that are responsible for the noisy generators.

What Makes Your Generator a Noisy Monster? 

According to a Cummings White Paper by Senior Acoustics Specialist Dennis Aaberg, whether it is a residential generator or a commercial generator, noise is produced by six major sources. The sources include engine noise, cooling fan noise, alternator noise, induction noise, engine exhaust, and mechanical noise. 

Different types of generators have different noise levels. For instance, standby generators and portable generators both of them have varying noise levels. Two main sources produce noise in portable generators, the engine block, and the exhaust system.

Like the rest of the motors, a generator motor produces a lot of heat and needs a cooling system to prevent overheating. Standby generators can either be air-cooled or liquid-cooled. The major difference between both the cooling system is that air-cooled systems are louder and not effective. Liquid-cooled systems are quieter and more effective, expensive to purchase and to maintain. 

Another mechanical part responsible for causing annoying noise in your generator is the muffler. Mufflers are meant to reduce machine noise. A malfunctioning muffler can play havoc with your properly functioning generators. 

One of the reasons your generator is noisy is the power output your generator is producing. The power generators that are stronger and produce more power are likely to cause louder noise contrasting to that of the weaker ones.

Factors That Help In Reducing The Noise Level Of Generators 

Pretty sure you must be aware of the reasons causing the noise in your generators. Now let’s look at the solutions to make your generators quiet as cricket. First and foremost, the tip is to buy one of the quieter model generators. 

Not all generators have the same noise levels, some are upgraded ones and some noisy beasts. The quieter ones function on 50 dB and deliver between 1600 watts or 2000 watts. However, if you have already purchased a generator then you want a way to reduce the noise so stick to the article for some helpful tips.

Soundproofing is a very good option for mitigating the noise levels. It’s all about blocking holes, but don’t go too serious with this. Generators need good airflow to prevent them from catching fire. Make sure while working with noise levels, you don’t forget to manage the airflow. 

It would be a very good option if you construct a soundproof cage around your generator. Once the generator is caged, the noise will be muffled while dampening the noise levels. You’re never going to soundproof your generator truly, so be smart in knowing the methods for reducing its noise.

Look for an inverter generator because the upgraded technology in inverter generators help in producing “no noise effect.”

Another way is to cover your generator’s feet with rubber. It will stop the vibrations caused by generators while operating. Ultimately it will have an impact on reducing the noise levels. Similarly, putting your generator on a soundproof mat will also reduce noise pollution.  

Installing sound deflectors is another great way to reduce the noise levels of your generators. A sound deflector is a device that helps in deflecting the noise away from a specific area. It is a worth buying device to install in the areas you don’t want to hear generator noise from. This device doesn’t make the generator itself quieter or reduce any of the noise it makes, it only keeps the noise away from reaching you.

Sound deflectors are readily available in the market. This is an ideal temporary solution if you are looking for something more permanent. To improve the effectiveness of your generator, you can combine sound deflectors with several other options.

Place the generator away from your living area and campsite. The closer the generator is to you the louder it’ll sound to you. Choose the right surface to place your generator. Placing your generator on unstable places will be noisier than placing it on a stable surface. Another tip is to install a larger muffler. It will help in making your generator much, much quieter.

The way the generator’s venting pipes are placed holds a greater significance. When they are turned horizontally, they are blowing the air to the outside, which means that they are blowing the noise horizontally as well. However, if you turn the pipes vertical, the noise will go in that direction as well, and make less noise, and it will not be as loud. 

Make sure your generator isn’t being loud because it’s broken. Get it serviced before trying to make it quieter. Proper maintenance and effective service procedure might save your generator from the damage and unbearable noise.


There is a never-ending list of great tips to make your generators quiet as cricket. Whichever method you choose, make sure the generator can still work properly. 

According to our research layering your generator with mass is the simplest and most effective method to make your generator quiet as cricket. If you decide to build the box, consider adding more layers of mass loaded with vinyl to ensure you’re reducing noise effectively. 

It’s something pretty obvious any of these adjustments will not make your generator completely quiet, but reduce the unpleasant sound that it is making. Overall, such measures will surely save your ears from the deafening noise of generators.
