How Can Your Reduce the Loud Noise a Generator Makes?

Ready for Honda 3kva generator deals but convinced you could not bear the noise they make? Well, here are five ways you can modify or add, so you can take your experience with owning a generator to the next level.

 

  1. Distance

 

The easiest (and quite often overlooked) way to reduce a generator’s noise is to the place the generator farther from you/your customers/community. The sound (energy) is distributed over a longer distance and therefore has a lower acoustic intensity if you move the generator farther away. The rule of thumb is that doubling the distance, in an open area, will get you a 6dB noise reduction.

 

 

  1. Acoustic Barriers – Fencing, Enclosures, Walls

 

Solid walls act as an acoustic barrier and limit the transmission of noise coming from a generator that is installed in a system room. Similarly, roofs and enclosures can reduce noise by at least 10 dB, while custom enclosures can have an even more significant impact.

 

If a case alone does not do the trick, use acoustic fences to create an additional barrier. Temporary acoustic fencing is an effective and quick solution for construction projects, supply networks and outdoor events. For larger installations, acoustic screens can be built and installed individually.

 

 

 

  1. Acoustic Insulation

 

The use of acoustic barriers to reflect sound waves only restricts noise beyond this barrier. To reduce noise and vibration in the generator housing/plant room, you must insulate the room to reduce the sound.

 

Hard surfaces with sound-absorbing materials are fitted out, or acoustic wall panels and ceiling tiles are installed. For industrial applications, wall panels made of perforated steel are the usual choice, but other materials are also available.

 

 

  1. Anti-Vibration Mounts (AVM)

 

Another good way to reduce noise is to limit it at the source.

 

The positioning of vibration protection brackets under the generator isolates vibrations and reduces noise transmission. There are many different options —rubber mounts, spring mounts, and dampers—and your choice depends on the dB level you need to achieve.

 

In addition to the insulation of vibrations at the generator base, the installation of flexible connections between the generator and all connection systems also reduces noise transmission to surrounding structures.

 

 

  1. Attenuators

 

For large systems, dampers or attenuators are the most effective way to reduce noise transmission.

 

A damper is a device that allows large amounts of air to pass through it but limits the transmission of noise. Air is forced between splinters (perforated high-density infill sheet), which absorbs the sound and reduces wavelength. A damping system can reduce noise to 48-85dBA at 1 m. As a rule, the more significant the damper, the higher the noise reduction.

 

Just in case you’re interested, what Is louder than a generator?

 

Here is a list of things that are (much) louder than the sounds made by a generator purchased from Honda 3kva generator deals:

 

  • Rock Concert (110dB)
  • Football venues (117dB)
  • Accelerating Motorcycle (120dB)
  • Jet engine (140dB)
  • Shotgun (160dB)
  • Rocket launch (180dB)
