Why are the Portable Generators Usually so Loud?

Are you disturbed by the sound of your portable generator? The constant roar and buzz of the generator disturbs the outing moments and creates a lot of hassle for you during blackouts. While there are some ways to quiet up your portable generator, it is also essential to know why your portable generator is making so much noise.

In this article, we will look at the reasons behind your portable generator’s loudness and offer some tips to help you reduce its sound.

Why are the Portable Generators so loud?

Cheap Design – One of the common factors behind portable generators’ loudness is the affordable design and inferior quality components installed by the makers. To reduce the cost, they let go of the basic features used to reduce generators’ sound. They forgo adding rubber pads, efficient mufflers, and soundproofing material while making the generator.

Poor Mufflers – Another common reason behind the loudness of your generator is the poor quality mufflers. Not only do portable generators come with cheap dampers, but you also don’t bother looking at them. Mufflers need to be replaced after a couple of years to ensure that they reduce exhaust sound effectively. You can find the best mufflers on the market here.

Vibrations – Loose nuts and bolts are also the culprits behind the noise created by your generator. They vibrate your generator, and as a result, your generator’s steel components make a lot of noise. It adds up to the running sound, and the intensity of the sound is increased.

Location – Often, you place your generator at the wrong location, or you don’t turn the exhaust away from your home or camping area. As a result, you have to bear the high sound of your generator.
