How Loud are Generators Overview
The need for a stable and constant power supply has greatly radicalized the world into needing alternative sources of electricity other than conventional power lines.
Every minute of a power outage means that someone is losing money or dying in a hospital theatre in the worst-case scenario. It is for such reasons that generators have become indispensable.
However, one major challenge of using a generator is the level of noise they produce. How much, you may ask. Well, it depends on the power of your generator.
Different areas have a limit to the permissible noise level. Typically, noise levels are measured in decibels- denoted as dB (A). The human ear has a noise tolerance of 85 dB; hence, anything above poses a health hazard. It is, therefore, crucial to choose the right generator for your area and the intended application. Generally, there are different types of generators which include;
- Portable generators
- Inverter generators
- Standby generators
- Industrial generators
- Induction generators
These generators are further divided into three categories based on their noise level, namely;
1. Silent Generators
Soundproof generators are fitted with a soundproof enclosure- a space built with unique composite materials that reflect sound waves and block them from traveling indoors or outdoors, and resilient material to absorb the noise and convert it into heat energy.
Consequently, the level of noise that would otherwise contaminate the surrounding is reduced significantly by approximately 15-20 DB.
These generators are ideal for areas that depend on as little noise as possible for productivity, such as schools, hospitals, courts, and even residential areas. Silent generators may come with additional features such as automatic low oil shutdown, a spark resistor, more silencers, and specially designed canopies for extreme silence.
2. Less than 75 dB noise level Generators
These generators are more powerful thus have a higher noise level. Note that for every 10 decibels generated, the noise becomes ten times louder. It means that a 75 decibels generator is ten times louder than its 65 decibels counterpart.
Noise level charts indicate that 75 decibels are equivalent to the sound of a flushing toilet. With this in mind, you can approximate the amount of noise to anticipate.
These generators are suitable for commercial premises or other areas with a high power output demand.
3. Less than 120 dB noise level Generators
Most high-intensity generators, such as industrial generators, lie in this category. The generators have noise levels above 75dB and produce the loudest amount of noise.
However, they generate an enormous power output and can support colossal manufacturing and Industrial areas. On average, 120 dB noise levels are synonymous with a rock concert, a loud symphony, or a sports crowd in a stadium.
These levels are relatively harmful; therefore, people subject to such extremes of noise require protective ear gear at all times.
Generators are undoubtedly vital in our day-to-day activities. However, the next time you sort to acquire one to supplements or backup your electric power supply, you surely need to add noise level at the top of your specifications least. If need be, seek expert advice on the most suitable options and, if possible, any noise reduction qualities to consider.
What decibel is a quiet generator?
A decibel (dB) is a unit of measurement used to express the magnitude or intensity of a sound wave. It’s often used as a way to measure noise levels in an area, such as how much traffic can be heard at night from within residential communities. Low volumes are generally 20 dB or less and are considered quiet, while levels between 40 to 55 dB are considered moderately noisy.
How loud is a normal generator?
Simply put, a normal generator produces between 60 and 120 decibels of sound. The lowest possible rating is 60 dB. The highest decibel level produced by most normal generators is 120 dB.
That’s the same volume as that created by a commercial jet engine. This level of sound is more than enough to cause serious hearing loss or damage after prolonged exposure.
Is 65 dB loud for a generator?
A generator produces an unbelievable amount of noise. It can be as much as 90 dB. The sound is akin to a rock concert in your living room when you are on the same property.
Modern generators nowadays are being built to reach a more tolerable noise level of around 65dB and lower for some other generators. In fact, most companies are proud to advertise this feature as the reason why their generators are quiet. Therefore, 65 dB is quiet for a generator.
How loud are home generators?
While sound ordinances vary, typical noise limits are in the 50 to the 65-decibel range at one’s home or workspace. As a rule of thumb, maintaining a generator outside your home or business place will not allow you to violate any local noise ordinances.
However, where the location is prohibited by law i.e being too close to a school or in residential areas, the noise level may be controllable by installing sound-control mufflers.
Most generators for home use are made to meet the threshold of these regulations while at the same time producing the necessary power as needed.
Is 74 decibels generator loud?
A normal human conversation ranges between 30 dB to 70 dB, anything louder than that would be considered noise. It would be safe to say that anything above 75 dB is likely to cause hearing damage and anything above 80 dB is harmful. A generator producing above 70 dB could be considered a loud generator.
Depending on the size of the engine driving it, the bigger the engine, the more noise it makes. Older generators make loud noise due to wear and tear, or simply, their technology doesn’t include mechanisms to minimize the noise.
Are Generac generators noisy?
Generac generators are the most popular in the world and for good reason. They provide all the power you need while being cost-effective and relatively quiet. Many have complained about the noise of portable Generators but this is not always true with today’s inverter technology.
Generator reviews online will mention the noise level but when it comes to talking about specific models, they can be a bit vague, which leads people to make assumptions based on experience with older Generac generators that aren’t necessarily true about today’s models.
Modern generators are effectively build to suppress the noise levels to around 65dB or lower. When considering buying a generator, these are the noise levels you should look out for.
You may also happen to already have a loud generator already. If the noise bothers anyone who lives near the generator, consider having a soundproof box built for it or install a muffler.
This will often make the noise tolerable to your neighbors and ensures you comply with local regulations.
