How to Reduce Generator Noise

104

Owning a generator is convenient and all, but what if it produces so much noise? A power interruption by itself is already annoying, so just imagine the stress if your generator consistently makes loud sounds.

Unfortunately, with massive generators, you really need to hire a professional since they require bigger soundproofing structures and a more complex repair. However, with smaller portable generators, you can definitely fix the problem on your own.

You need to find a few materials and tools before starting the process. Here’s how to reduce generator noise:

Add padding and change the exhaust.

For the first part, let’s focus on the generator’s padding and exhaust. Luckily for you, you’ll start with the easiest steps.

Adding the Rubber Tiles

  1. Place your generator in a spacious area. It should be the loudest object there so you can easily monitor the reduction of sound.
  2. Arrange the rubber tiles on the ground.
  3. Place your generator on the customized rubber pad you created.

Installation of the Exhaust

  1. Buy a motorcycle exhaust.
  2. Make your own pipe system to connect the exhaust to the generator. Just make sure that the exhaust is vertical to the generator.

Reduce vibration to minimize noise.

Vibration is directly related to generator noise. So, if you’re going to solve this problem, your generator will produce less sound. Learn how to add the anti-vibration system to the engine’s housing.

  1. Find the engine block. You’ll see it when you observe the engine’s frame and spot the screws securing it.
  2. Replace a stock bolt with a new one.
  3. Place a rubber washer outside the metal washer.
  4. Sandwich the frame by reversing the sequence on the other side.
  5. Check the arrangement from left to right. It should be a bolt, metal washer, rubber washer, the engine’s frame, rubber washer, metal washer, and bolt.
  6. Repeat the steps for all bolts. Tighten the entire anti-vibration structure.

Build an enclosure.

Finally, we’re on the last part of the process. Here are the steps:

  1. Make sure there’s a space between the cinder block walls and the generator. It should be six inches to one foot. Mark each side so you won’t get lost in the process.
  2. Stack the cinder blocks around the generator except on the side where all the connections and switches are placed. The walls should be one foot taller than the generator.

Conclusion

As a reminder, all details here on how to reduce generator noise are only applicable to smaller portable models. Never hesitate to hire somebody to help you if your home generator is huge.
