Traditional generators are basically produces noise when running. Why? Because, it is made of motors that produces power needed to drive your appliances.
However, many of us hate those noises coming from these generators, right? This is the reason why we have to search for silent generator for your own personal needs.
Generator Decibel Comparison
In case you’re wondering how many decibel is considered as quiet generator.
Human ear is sensitive to sound it can determine wide range of sounds coming from different sources. From a slightest blow of a wind to a loudest explosion though, excessive sound can damage your hearing.
What is decibel?
Decibel (dB) is a unit which is use to measure the sound intensity. Basically, one decibel is equivalent to a one-tenth of a bel. The name bel is taken from Alexander Graham Bell. Zero decibel does not mean no sound at all, it is a threshold of a human hearing. Meaning, it is the least possible sound your ear can hear.
So, if you’re going to compare a 0 dB to 1 dB, the difference between the two is obviously 10x louder. Therefore, from 0dB to 50dB is not 50x louder due to the fact that decibel scales are algorithmic increment.
If we going to talk about the loudness of a generator, it is express in A-weighted decibels which is in dBAs. It is a measure of sound in the air perceived by the human ear.
In A-weighted system, the decibel equivalent value of a low frequencies are reduced as opposed to the unweighted dB which is no correction made for audio frequency. The correction is being made due to the fact that human ear is less sensitive at low audio frequency typically below 1,000 Hz, compare to high frequency audio.
To further understand this, dBA in computer system is used to denote the loudness of fan inside the microcomputer which is used to cool the system components. Its typical rating is 25dBA that represents above the threshold of hearing. This value is equivalent to a person whispering in a quiet environment.
How many decibel is a quiet generator?
Generators dBAs are measured and compare within the industry @ 7 meters. To meet the EEC regulations all generators have to be marked in LWA which is different measurement of sound at different distance.
To give you an example, the Yamaha EF2000iSv2 has 51.5 dBA at quarter load measured @ 7meters away. However, you should be aware the fact that not all generators have LWA marked on them while, many of them don’t have the industry rated at 7 meters.
To answer the question, how many decibels is a quiet generator?
Generators that operate at 50 dBA to 60 dBA is consider as a quiet generator. In short, the higher dBA value the louder the generator is.
These noise levels are comparable to a running fridge and air conditioning system or a normal human voice conversation. Generators that can achieved this sound levels are inverters with 1,000 to 2,500 watt power capacity.
Some generators are rated in between ranges like 52 dBA to 59 dBA. It means that, the lowest noise it can deliver is 52dBA @ idle condition and 59 dBA @ full rated output. However, some generators have written on their specs with ¼ rated load and not the full rated load noise level.
Keep in mind that, your generator doesn’t always run at quarter load and most of the time you are using more than half of its load while sometimes at full load.
The noise level your generator increases as the load gets heavier. Be sure to know the generator’s peak noise level when buying a quiet generator.
Silent Generator For Home Use
Home backup power is important not only for business establishments. However, if you’re running your own home business generator is definitely a must, right?
If you don’t have any idea when the power will resume it’s just like you’re guessing how much money you lose during the power is out. Those who live in areas with prone to bad weather like storms, hurricane, tornado, typhoons and flood you probably experience more frequent power interruptions than other regions in the country.
A silent generator for home use is a perfect solution to your problem rather than waiting in the dark and guessing when the power will come back again.
