The problem starts when it is heavier than you realized and you are not able to move it by yourself. Worse, when you turn it on, it sounds like a jet engine and your neighbors don’t hesitate to complain.

Noise might not be at the top of the list of your concern when you purchase a generator, but it is a hugely important factor when you start using it. So if you are struggling with the annoying noise of your generator, we will show you how to quiet a generator right now!

Why Are Generators So Noisy?

Generally, Portable generators generate electrical energy through the engine, which produces a lot of noise even in some expensive models. The noise level is measured in decibels.

Most of the generators produce noise levels in a range from 60 to 90. But sometimes it crosses over the 100dB sound level. Most likely, the more inexpensive a generator is, the louder it will be.

A generator that contains 60 to 70 decibels will seem as loud as a vacuum cleaner or a dishwasher. While the noise of a dishwasher or laundry machine is quite tolerable for a short period of time, the constant sound may become overwhelming.

In some other cases, a generator may start to produce more noise when it needs repair. If you notice any smoke, or if you are having difficulty starting it up or experience frequent power shortages, you should call a professional to have a look.

How Loud Are Generators?

Many residential areas have noise restrictions, especially at night which puts a drawback on using a generator. So if you are intending to purchase a generator for home use or a work shed, you have to consider its noise level of it.

Also, loud generators are not a good choice for camping or even for your home unless you want to turn your neighbors into your enemy.

According to the National Institutes of HealthSounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.

Luckily most of the generators are measured on a standard noise scale in the factory that ensures it is perfectly fine to run it under any circumstances.

Normally most of the expensive and great models have a noise production level from 60 to 90 Dbls. However, some generators contain a noise level of 80 to 90.

There are a few generators that exceed 100 DBls. So, you can either use a generator sound deflector or use some materials to reduce the pollution that your generator is causing.

Why Should I Silence My Generator?

Silencing or muffling a generator is not only a reason to keep yourself free from being bothered but also a kind and generous act for other people around you.

Moreover, you don’t want your kids to grow up in an environment where sound pollution is at its peak. While camping, you should not scare wild animals and birds. So silencing or muffling your generator is a must-act to perform.

Can You Put A Silencer On A Generator?

The generator companies are capable of building quiet generators by using soundproof technology and silencers that can make a generator quieter than usual. The silencers are made of rubber which makes sure the generator produces low noise levels and prevents vibrations.

This is the most effective process to make a generator quiet. The process is called muffling or silencing the generator. The generator box contains special technologies that make your generator produce less noise and vibrations.
