Whenever we hear a word generator, the second thing that comes to our mind after power is loudness. But not all generators are loud and produce an irritating sound. There are many quiet generator models that hardly produce a sound louder than a normal conversation.
Noise pollution affects both of our health and behavior. It is responsible for hypertension, hearing loss, stress, tinnitus, cognitive decline, and more.
According to a review of studies in the year 2000, when pregnant women get exposed to less than 65 dB noise level, they get a small decrements in the birth weight.
A study conducted in 1993 by Cornell University says that noise pollution causes cognitive development delays in children.
Also, according to an EPA report, 45 dB is the recommended noise level for indoor residences.
Therefore, it is necessary to purchase a quiet generator to keep you and your environment safe and healthy. So, here we have a list of seven best quiet generators that you can consider to buy one.

In this section, you are going to know which of the factors you should consider before purchasing the best quiet generator.
The first factor must be the noise level as you are looking for a less noisy generator. A generator operating at 50 dB will surely not bother anyone. But a noise level of more than 60 dB can. Still, it is not that loud but to keep your environment free from an irritating noise; a generator having less than 60 dB noise level is a must.
But it doesn’t mean that you can’t buy a generator having more than 60 dB decibel rating. Keep it away from you to relax at home or enjoy your outdoor activities.
But one thing you should keep in mind that the engine size and the power generating capacity of a generator affect the noise level. If you are looking for a 3,000 watt to 4,000-watt generator, you can’t get a quiet unit. For this, a 2000-watt generator is ideal.
Also, how much load you are applying changes to the noise level. Draw a little power from your generator; it will keep quiet during operation.
Fuel Tank and Runtime
Before focusing on the fuel tank size and runtime of your generator, it is necessary to find out how long you will need to run your unit.
The fuel efficiency of the generator and its tank size affect the runtime. A generator with a fuel tank size of one gallon or more can easily give you 10 hours of runtime at 25% load.
You should also check your generator’s control panel to make sure that the type and number of power outlets available are according to your needs. Along with minimum two 120V AC household receptacles, a 12V DC with or without USB adaptor and 5V USB ports are a must.
If you are finding a generator for your RV, then make sure it has an RV outlet.
Overload protection with alarm and low-oil shutdown with oil alert light indicator are the most common safety features and must be the part of your generator. The indicator lights are important to let you know the reason behind the engine shutoff.
Both of these safety features are for the protection of the generator’s engine and your appliances.
Which one is quieter? Inverter or conventional generator
Inverter generators are much quieter as compared to most of the conventional generators. The reason for this is the smart-throttle system that changes the engine speed according to the load applied. Not all the time, the engine runs at the same speed; it adjusts its noise and output according to the power you are generating. Also, inverter generators come with enclosed frames and feature oversized mufflers that reduce the engine noise.
What are the benefits of a quiet portable generator?
There are various benefits of using a quiet portable generator.
First of all, a quiet generator produces less sound that is ideal for those who hate listening to the awkward generator sound.
Second, it consumes less fuel.
Third, you can take your generator anywhere because of its great portability feature.
Will two small generators connected in parallel make less noise than a powerful unit?
No, two less powerful generators will produce more sound than a single power generator. Therefore, it is better to use a powerful unit when you need to generate more power rather than connecting two small generators in parallel.
How to make generators quiet?
If you don’t have a quiet generator but desperately want to reduce the noise level of your unit, then there are various things that you can do to make your generator operate quietly.
You can either install a sound deflector or build an enclosure for your unit. Also, you can install a big sized muffler or change the position of the exhaust pipes from horizontal to vertical.
Is it ok to operate your generator at low load every time to keep the noise levels on a lower side?
No, it is not ok to operate a generator at low load (25% load) most of the time. Your generator performance will get affected overtime. Therefore, sometimes it is necessary to run your generator at 50% load or higher to increase the lifespan of your unit.
