is there a silent generator?
If you have experience working with a generator or have seen it up close at least a few times, you must have noticed that its very loud sound will be a serious nightmare for its surroundings.
Given that the generator is also widely used in residential areas, this generated noise can be a serious nightmare.
The annoying sound of an generator not only affects normal people, but can sometimes even damage the hearing of operators and workers.
This has led most generator manufacturers to try to produce low-noise products. You've probably come across the phrase "silent electric motor" several times in online advertisements or even video teasers, but how true is that phrase.
Is there a silent generator and is it possible to be a silent generator at all in terms of engineering and technique? Is this a trick to increase the sales of generators? In this memo, we seek to explore this issue and we intend to provide you with a definite but true answer, dear friends.
What is the high noise caused by the generator?
Before we get to the main question, let's look at what makes these devices so loud. If you are familiar with the generator, you know that in this practical device, a motor part does exactly what is done in a machine; converting the chemical energy of fuel into kinetic energy through combustion.
Or the engine noise in cars and passenger cars may not be so annoying, but if you lift the hood of the car, you will notice that the story is different.
In a generator, we see the same engine as a car, but without any insulation or cover like a hood around it! Well, of course, that sounds annoying.
The constant movement of the piston due to combustion, along with the close movement of parts and components in any engine, will cause noise.
The more insulated an engine is, the less noise it will make, but it will not be possible to produce this type of product. In addition, a significant portion of the engine's sound in the car will be transmitted to the exhaust duct and suffocated in the car's exhaust depot.
It is clear that such components do not exist in an electric motor, and the sound of the engine's combustion will reach the ears of the environment without any barriers or direct.
What are some ways to reduce the noise of a generator?
Now the question is, what solutions and methods do manufacturers have to reduce the noise of generators? Here are some solutions.
Before addressing these solutions, it should be noted that these solutions are not implemented by users and should be done by the manufacturer during the design and production process, but sometimes you may be inspired by them to find experimental solutions to reduce the sound of the generator.
Covering the engine section with sound insulation: The better the environment around the engine, the lower the sound of your generator.
Engine alignment: Internal combustion engines are usually more aligned at certain angles and produce less noise. This is due to the way the forces interact, which is why we see less noise in the engine at certain angles.
Limiting the output noise with the warehouse: In car exhaust, a section called the exhaust warehouse helps to control the engine's noise output. In a generator, you can also suffocate the sound by embedding some parts.
Reducing moving parts and stabilizing parts: The smaller the moving parts and the less common the term generator, the less noise the device produces.
Further integration is an important factor in reducing the noise produced by this device. Sometimes an increase in age and, in parallel, a decrease in the health of a generator can cause parts to malfunction, and this loosening will increase its noise.
Is a silent generator available?
Both yes and no! You don't have to be confused about this. From this point of view, we answer the question in the affirmative that many manufacturers of electric motors have been able to greatly reduce the noise of this device and, in practice, to produce quieter products than other generators. But that hasn't stopped us from seeing completely silent generators.
So there is sound in any case, but sometimes it is greatly reduced in some products. Some manufacturers will greatly reduce the noise by relying on the above and producing an expert generator.
In general, as the taste of the market shows, the desire of manufacturers to reduce the sound of generators is very high and this issue is considered as a winning card in competition with other brands. However, this can increase the price of the generator.
Is being silent always just an advertisement?
You may sometimes come across baseless claims by unreliable manufacturers, and their sole purpose is to raise the price of the generator, but super-silent or completely silent generators have significantly less noise. Again, their voices are not exactly zero.
In some models, such as the Honda EU200i, Atima AY2000i, and Yamaha EF2000iSv2, the sound is reduced to less than 52 decibels; this number is equivalent to the sound of a normal, quiet conversation one meter away.
You may be very excited to hear this sentence, but keep in mind that this amount of sound is present in ideal working conditions and a quarter of the time, and in other cases this number can be much higher.
However, if you have experience working with a generator, it may still be more satisfying for you. However, the claim of being silent is absolutely baseless, but if you look at it in relative terms, it is not far from the truth.
However, when you buy and check the specifications of a generator, you can see how loud it is and whether it is suitable for your use.
