You may be wondering why some generators don't list their decibel ratings while others do.
Unfortunately, not all generator manufacturers publish the decibel ratings for their generators.
There are currently no industry standards or requirements for generator manufacturers to follow during noise level testing.
Because of this, manufacturers can test the noise levels under whatever conditions produce the most favorable results.
Why Some Manufacturers Don't Measure Decibels
Everyone hears differently, and although a generator may list its decibel rating, its sound will still vary from person to person depending on the location of the generator and where the person is standing.
Therefore, decibel ratings aren't always as accurate as they were intended to be, which is why many companies are hesitant to provide any at all. The location of the generator, the direction in which the exhaust is pointing, and the type of generator you have all influence the noise level.
Here are some guidelines on how loud your portable generator might be.
Inverter Generators are Quieter
For a quieter generator, consider an inverter generator. They're much quieter, and they produce cleaner power that's safe for devices such as laptops. However, inverter generators are limited to sizes up to 5500 watts.
Inverter generators use a different type of alternator to create very clean AC power and reduce size, noise, and fuel consumption.
