Make Generator Quiet
Natural disasters occur often, and Power failures happen. During an emergency, your only choice is a portable generator. You just have to get it out, fuel it up, and pull the starting chord- now you have your own mini power station! But generator has its own drawbacks, regardless of its helpful nature in emergencies. I am sure you all know that the biggest drawback of power generators is they are very noisy.
Moreover, when you go on camping the one thing without which the camping is not possible is a portable generator. Normally you go for camping in order to explore nature. It’s all about moving away from the modern world’s chaos and pollution. Unfortunately the noise can disrupt all this if you or any other person in the campsite has managed to bring a loud generator
But the question is how to make your generator quiet as a cricket? Fortunately, there are some things that will make your generator quiet, and then you can use it anywhere you want without the disturbing noise! The lists of methods that will help in making your generator quiet are listed below.
- Build a Sound Proof Box:
The most effective way to keep your generator quiet is to create a sound proof box. The main concept is to have something that will block the generator’s sound or diverts it from listening ears to somewhere else. Make a box that runs across the top of your generator or in which your generator is placed. You have to leave a gap or a little hole so the electric cords can come out of the generator.
The inside of the box is lined with material that absorbs sounds and some instructions for DIY recommend the use of medium density fibers and mass loaded vinyl. You can purchase proper sound absorbing panels, but you can make similar effect using material from foam board, bath towels, or cushions and can save money. At least one inch of soft porous material will be in the center of the enclosure to help absorb the vibration.
The fastest and easiest thing to do is to take some plywood, or better yet drywall, and place them over the generator. Both plywood and drywall have sound-absorbent characteristics and the key point of this concept is the deflection of sound waves into from the generator into the earth. This can minimize generator noise by approximately 10 dB.
- Modify the exhaust Muffler:
The motor produces sound and most of it is driven by exhaust. The purpose of the muffler is to minimize the echo of the sound produced. If you have ever encountered a car or motorcycle with a broken or a missing muffler you must know what is the role of a muffler in reducing noise. While you can’t do anything about the electric motor sound, it can help minimize the noise the generator creates by adding a larger and a new muffler. Another advantage of a good muffler is that not only does it significantly lower the noise level; it also reduces the noise frequency.
- Correct Placement of the Generator:
One more thing you can do to minimize the generator’s noise is to reduce the vibrations it generates. So it doesn’t matter whether you are camping or using a power generator at your home, don’t place it on a concrete or a wooden floor. Actually, it is better to fully avoid hard surfaces.
Place the generator on the ground so the Earth absorbs the vibrations. As an alternative, an anti-vibration sheet can also be placed under the generator. But if not available you can utilize other materials as long as they can handle the heat. Use rubber sheets or foam if your generators gets heated easily but if not then blanket or thick clothes will also work for you.
- Place the Exhaust Pipes vertically:
There will be horizontal exhaust pipes in the normal generator. The main purpose of transforming them in a vertical position is to direct sound waves into the air rather than to you or to your surroundings. Of course some amount of noise will still travel horizontally, but the sound will be reduced to a certain point. If the exhaust pipe is not placed vertically at least, place it in an opposite direction of your house or camp.
- Use the Water technique:
It may seem a risky and an illogical choice, but it does actually work very well to minimize noise from the exhaust of the generator. You just need a water bucket and a pipe. So all you need to do is attach the pipe at the end of the generator’s exhaust and place the other end in the water bucket. If you’re worried about water entering into the generator, then make a very small hole using a pin in the pipe. This will bring an end to pressure.
- Install Sound Deflectors:
Sound deflector is an entity or tool used to change the noise direction. Sound deflectors will certainly make a difference when your generator is placed in an indoor position such as outhouse, and you are not planning to place it somewhere else. It is important to note that it will not make anything sound proof.
The goal of sound deflector is to lessen the vibration and sound, which only means that the chance of noise reaching you is less. As a result, total airborne noise will also be minimized. They can be purchased conveniently, and this is a best solution for reducing sound of a portable generator.
No doubt generators are very useful and you’ll be glad to have one when there is no power supply. But it can be very unpleasant to live and sleep with continuous noise, so try to minimize the noise as much as possible. You want to stop the irritating sound of the generator as much as possible so that you can relax and enjoy electricity without being continuously annoyed by a powerful sound.
Some of the ways mentioned above will surely help to reduce noise, but a robust, well constructed box with layers and acoustic caulk will stop the noise completely.
