Understanding the factors that influence the acoustic power of a silenced current generator and understanding the different sound levels is very important in order to understand the main differences between the various models on the market.
The acoustic power of a current generator is expressed in decibels, dB or dBA . The higher the dBA for a generator, the louder the noise emitted.
For comparison, a person's calm breathing is 10 db, whispered conversation is 30 decibels; a normal conversation is 60 decibels; while a vacuum cleaner or a busy street can be as high as 80 decibels. Powers above 140 decibels cause pain in the eardrums and can cause hearing damage.
There are no universal standards for the amount of permissible noise for generators. Rather, each model is different. Some manufacturers are famous for their super quiet motors with very low decibel levels; like Honda inverters.
In productions, sound measurements are taken from one meter away for convenience. However, the industry standard declared distance is (7 meters), unless otherwise specified. In general, the sound level of the generators varies from about 50 dB to 110 dB.
There are no universal standards for the amount of acceptable sound levels of a generator. Rather, each application and environment in which the generator is being used is different.
Generally speaking, the quietest generators should have values below 60 decibels. And if the only difference between two generators is only a couple of decibels, don't think about these 2 decibels lightly, because in reality, it will make a big difference in the sound level. In fact, for every 10 decibel increase in your generator sound level, the noise increases 10 times. A generator rated at 70 dB is ten times stronger than a generator rated at 60 dB.
The noise emitted by a silenced power generator occurs due to some factors, such as the size of the motor, the exhaust, the vibrations of the unit. Understanding the reasons behind quiet electricity generation will allow you to make the right choice to choose the quietest generator that best suits your needs.
Generator noise varies according to the size of the engine and its load and can be as high as 110 decibels. One of the main factors affecting the sound of a generator is the size of the engine. Sometimes this can vary depending on the generator model. If a couple of generators have the same power output but vary in noise level, this could be attributed to a better engine. However, the more power the generator produces, the more noise it will make. For example, a 3000 watt generator will be louder than a 2000 watt generator. In addition, the decibel level also changes according to the load required by the generator.
Aside from the size of a generator, the noise produced by the engine depends on many other factors. For example, the density of the air around the generator. The surrounding environment can affect the evaluation of the sound produced by two completely identical generator sets. The exhaust also contributes significantly to the overall noise level of a generator. Not to mention the cooling fans which, in addition to cooling the system, are also responsible for altering the silence of a generator during operation. The sound of a cooling fan varies based on the operating speed and design of the fan.
Inverter generators tend to be significantly quieter than regular generators. Thanks to their compact design, they use a smaller motor, which consequently reduces noise levels. The casing of the generator set body also reduces the sound. The inverter generators are built with insulating and soundproof materials that absorb the sound vibrations produced by the generator. Other silent portable generators are available with a closed acoustic housing that dampens the sound produced. In this case, the noise level is lower than in an open generator.
