There are several solutions to this problem – you can purchase a model with a silent operation mode, or change the fuel type or provide the generator with sound insulation. But about everything in order.

What is a “silent” generator?

  • If you are just planning to get a generator and are worried that it will make loud annoying sounds, we recommend that you purchase a low–noise (silent) generator.
  • The sound of these models differs from the more “loud counterparts” due to the fact that such models have a smaller engine size, and they have less power.
  • The solar generator can also boast of quiet operation – it practically does not make any sounds. This type of generators is recommended to be used even indoors

If you are already the proud owner of an “ordinary” portable generator – do not rush to despair. In your case, there is also a solution.

How to make the generator work quieter?

  • As a rule, the bigger the engine, the louder it works. This also means power – therefore, a larger and more powerful generator emits noise many times more than a generator with a weaker engine.
  • Also, the volume of the engine in some sense depends on the type of fuel – generators running on liquid fuel make enough noise, but it should be said that the most “noisy” fuel is diesel.
  • Based on the first two points, the following conclusion can be drawn – try changing the engine in your generator. This can significantly reduce the volume of work, but keep in mind that the power is likely to decrease along with the volume.
  • Another option is special noise suppression systems or sound insulation.
  • Noise suppression systems are several parts in the design of the engine that reduce the noise from the generator. Some manufacturers initially include these parts in the generator, but if they are missing, you can pump the generator yourself.

Usually, the noise suppression system consists of: a muffler, rubber sound insulation, rubber gaskets between the main body and the engine, a frame or casing with noise reduction.

  • Sound insulation – in a sense, it is the same noise suppression system. Usually, special sound-absorbing cases are purchased for sound insulation. A generator is placed in the case, and the design absorbs and suppresses excessive noise.

Also, for a quieter operation of the generator, you can configure it. How to set up a generator for quiet operation:

  • Adjust the position of the exhaust pipe. Exhaust pipes that are located horizontally emit the most noise. Point the exhaust pipes upwards so that they are not facing anything directly (so that sound waves do not reflect off surfaces)
  • Add a silencer. Many portable generators come with it right away, but if you are not satisfied with its effectiveness, you can replace the muffler with a better one.
  • Install sound deflectors. Sound deflectors are solid materials capable of reflecting sound waves.
  • Install rubber gaskets to absorb noise.
