When it comes to dealing with noisy generators, there are several ways you can go about trying to reduce the noise. Some methods are better than others and some will cost more than others.

It may be that your existing generator is already quieter than it could ever be since manufacturers do their best to reduce noise levels before a unit heads for the market.

In the end, however, all you can do is try different things until something works for you.

1. Location of the Generator

Install the generator as far away from buildings as possible.

In order to reduce noise pollution caused by these machines, they should not be placed under windows on a house or inside garages where people work on vehicles because vibration noises can easily travel through walls and structures which then transmit this amplified sound into nearby living spaces such as bedrooms or kitchens.

If you must site a generator next to your home, use it sparingly for emergency power needs only and never run more than one machine at any given time.

It is also recommended that generators running in such close proximity to homes be located in an area that is electrically isolated from power lines running into your residence, like a concrete pad or if possible inside of a garage.

2. Check Other Devices Around the Generator

It’s quite common to have someone complain about engine or generator noise and not realize that the problem is neither of these items. Rather, it stems from improper installation, bad fuel, low oil condition, or other factors.

For example, if your generator is installed too close to an outdoor air conditioner, water pump, or other mechanical devices, it won’t be long before you notice that the generator and everything around it is making more noise than usual.

Before you contact a technician or your dealer about engine troubles, see what’s happening in your shed.

3. Lower the Generator’s RPM

Generator noise can be reduced by lowering the RPM of its engine when sound levels become excessive, especially for those who live close to their neighbors or are located near dwellings where people are trying to sleep during daylight hours.

Using lower than standard RPM settings will allow homeowners to reduce their chance of complaints from angry neighbors and may also help prolong generator motor life as well as fuel efficiency if you do not give yourself more that is required (i.e., extra noise) just because you can!

4. Check the Generator’s Condition

When a generator goes bad, it’s usually because of wear and tear or damage caused by poor handling when moving the unit from place to place.Other problems can occur if fuel levels are too low, water gets into the carburetor (dirt also causes this), valves get gummed up with carbon deposits, spark plugs go dirty or oil becomes contaminated.

If you have a gas-powered generator that allows you to drain the tank, remove any water that might be there before adding fuel for the next time the unit will be used.

Remember to follow all instructions in your owner’s manual about adding fuel, oil, and water. If there’s too much oil in the crankcase then air bubbles will develop in the fuel lines and eventually cause a noisy situation.

The fuel supply lines should be kept clean and free of debris or water. Make sure there are no restrictions in the hose connections as this can also cause noise.

The first thing you can do to reduce noise from a gas-powered generator is to ensure that it is running smoothly and producing enough electricity for the task at hand. If there are mechanical issues such as these, noise is usually high on the list of troubles.

It also means keeping the air filter clean, changing spark plugs when necessary, making sure valves are lubricated properly, and checking oil level since overheating causes excessive noise.

5. Add Soundproofing

A good way to reduce generator motor sounds is by adding some type of barrier or shield that has been designed with dampening attributes for reducing high amounts of ambient noise between rooms or areas where people sleep, work, eat or study.

Fit an enclosure around the generator that will isolate its loudest parts from those areas where people live and rest in your home (most importantly bedrooms). This can be done using common products available at most hardware stores, like sheets of foam board insulation that are commonly used in garages and workshops.

The cheapest way to quiet a generator is by simply adding foam covers over all outlets on machines, as well as placing insulation around spark plugs, mufflers and other high noise producing components on the unit.

If you plan to use generators in more remote areas of your home make sure these units are mounted on skids so they can be moved easily if necessary for storage during winter months.

This material is not expensive but can dramatically reduce the noise levels coming from a generator by absorbing sound waves before they become airborne.

Make sure to fit weather stripping around doors leading into your generator room as well as tightly fitting windows to prevent air leaks which would allow noise pollution to enter other parts of your home.

6. Replace Your Generator’s Mufflers

A muffler can be fitted onto the exhaust pipe of a generator unit in order to reduce noise pollution associated with high decibel levels produced when start-up procedures are utilized.

The muffler must fit tightly to the exhaust pipe as well as be properly vented and cooled with powerful fans.

In cold-weather areas of the United States, you may want to consider using such a muffler system that incorporates carbon dioxide or dry ice into its design for reducing noise pollution in homes located near areas where snowfall is common (generators must be operated indoors or within an enclosure when used during cold weather periods).

These units are usually installed by qualified technicians and will cost a few hundred dollars to have installed but they are well worth the price if you have neighbors who find your generator to be more of a nuisance than an asset during times of power loss.

Conclusion

When it comes to generators, there are many things you can do to help reduce the noise. Some methods will be more expensive than others and some may not have much of a difference while other solutions might make your generator quieter.

It could also be that your existing unit is already as quiet as possible, so try these tips before buying a new one. If you’re still unsatisfied with how noisy or loud your generator is after trying all of these different techniques, take a look at our article on the best quiet generators.
