How Loud is a 50kVA Generator?

How Loud is a 50kVA Generator?

Generators are indispensable tools in various scenarios, from construction sites to backup power solutions. However, one of the often-overlooked aspects of using a generator is the noise it produces. If you're considering a 50kVA generator, understanding its noise level is crucial, especially if it's for residential use or in noise-sensitive environments. In this post, we'll delve into the decibels and discuss how loud a 50kVA generator can be.

Understanding Decibels (dB)

Before diving into the specifics, it's essential to understand how noise is measured. Sound levels are gauged in decibels (dB), a logarithmic unit that quantifies the intensity of sound. For context:

  • A whisper is about 30 dB.
  • Normal conversation is around 60-70 dB.
  • A lawnmower can be around 85-90 dB.

Noise Levels of a 50kVA Generator

The noise produced by a 50kVA generator can vary based on its design, brand, and enclosure. On average:

  • Open or Basic Generators: These can produce noise levels ranging from 85 to 95 dB or even more. The lack of any soundproofing or noise reduction mechanisms means they can be quite loud.

  • Soundproofed or Enclosed Generators: These are designed to minimize noise and can have noise levels ranging from 65 to 75 dB, comparable to a vacuum cleaner or a busy office environment.

Factors Influencing Noise Levels

  1. Generator Design: Some generators are designed with noise reduction in mind, incorporating mufflers, soundproofing materials, and other noise-dampening features.

  2. Load: Generators can be louder when operating at their maximum capacity compared to when they're running at half-load.

  3. Placement: The noise can be amplified or dampened depending on where the generator is placed. For instance, a generator placed close to walls might reflect more sound than one placed in an open area.

  4. Enclosure: Enclosed or canopy generators are designed to reduce noise. These enclosures are not just for soundproofing but also protect the generator from environmental factors.

Mitigating Noise

If noise is a concern, consider the following strategies:

  • Distance: Place the generator as far away as possible from areas where the noise could be disruptive.

  • Sound Barriers: Use temporary walls or barriers to block and absorb some of the sound.

  • Anti-vibration Mounts: These can reduce the vibrations, which can contribute to the overall noise.

  • Choose Wisely: If you're in the market for a generator, prioritize models known for quiet operation.


While a 50kVA generator is a powerful tool, it's essential to be mindful of the noise it produces, especially in residential areas or events. By understanding the expected noise levels and taking steps to mitigate them, you can enjoy the benefits of uninterrupted power without the disruptive roar. Always consider the specific needs of your environment and consult with experts to make an informed decision
