Generator noise can be extremely annoying and can result in headaches. So read on to know how to make your generator quiet as a cricket.
Generators are undoubtedly the best machine to provide backup electric powers. Whether it’s for your office or home or even camping, a generator has become an essential part of our lives.
But nobody can deny the fact that Generators are loud and make a lot of noise. A Generator makes around 60 to 100 decibels sound due to its tools and parts. As a result, sometimes the sound becomes so unbearable that people don’t even want to use it.
But as they are the best backup source, we have no option but to use them. That’s why it’s essential to know how to make your generator quiet as a cricket.
How to make your Generator Quiet as a Cricket
There are many ways to make your generator quiet. And adding a super quiet generator muffler is one of the best ways to do it. Besides this, we have found several other ways to do the job.
1. Soundproof Box for Generator
Yes, generators indeed make a lot of noise. But there are some factors behind the noise of a generator. Vibrations of the engine, the noise of the fans, exhaust noises are some of the culprits behind it.
To keep the noise inside the generator or to prevent them from coming outside, building a soundproof box for your generator can be a feasible idea. Yes, the box is gonna add a little more weight to the generator but isn’t it better than noise pollution?
You can buy a soundproof box from stores or even make one by yourself. Here, we’ll be sharing the procedure to make a soundproof generator box at home-
For this, you’ll need
- Fiberboard of medium density
- Foam mats
- Ventilation duct
Most of the items that we mentioned above are easy to find other than the Mass Loaded Vinyl. Check it out here. As we’re adding a ventilation duct in the soundproof box, the box will not act as a complete soundproof one. But it’ll reduce the sound to some extent.
To build the box
- Take a measuring tape and measure the dimension of your generator. Normally, the size is written on the body as well. So skip the measuring part if it’s already given. Spare a few inches on all sides.
- Now take the MDF (Medium Density Fiberboard) and cut them for all six sides. Carefully cut them down to the dimension of the generator.
- To add the ventilation hole, calculate the ventilation duct first and then cut it to its size.
- The ceiling panel of the box should have a ventilation duct. The other one will be in the wall panels. Check if the two holes are diagonally cut or not.
- Take the MLV and lay them on the panels to make a layer. Attach the MLV and the MDF with glue. Remember to seal down each of the edges of the box using green glue.
- After you’re done gluing the MLV and MDF, use the foam mats and make a layer. The foam mats don’t really absorb the sound. Rather they prevent the reflection of sound.
- Again, use the green glue on the edge of the box to seal it. The sealing prevents the sound from coming out.
- Now, check if the box is secured or not. You can use screws or other fittings to close the box. To ensure a good air supply in the generator box, don’t forget to use ventilators.
This is one of the ways of how to make your generator quiet as a cricket. As you finished making this box, here are a few things you should remember-
- Keep the generator within the box in a dry, airy, moisture-less surface
- Check if the box gets overheated or not
- Always put the box over a solid surface like concrete to reduce the vibration of sound.
- This idea can come in very handy, especially for small, portable generators.
2. Using a Super Quiet Generator Muffler
Generator quiet mufflers are one of the most common items used to quiet a generator. The size of a muffler plays a bigger role in quieting up a generator. The short ones can get the job done, but the longer ones have been proven more effective.
Although using a quiet generator muffler fails to do the job alone, noise pollution occurs due to the exhaust. So what we can do is, add these components with exhaust and turn it into a quiet exhaust for the generator.
3. Using Baffle Box
A baffle box is also a type of soundproofing box. But there are a couple of differences between them. While a soundproofing box keeps the sound inside and prevents it from coming out. On the other hand, baffle boxes eliminate the airborne noise.
The construction procedure of a baffle box is the same as the soundproofing one. But here, you don’t have to add a layer at the bottom. Just leave it blank. So the box will be covered from five sides instead of six. And you just have to place this box above the generator.
4. Using Sound Deflectors
Sound deflectors can only be used in generators that are permanently stored in a shed or box. It won’t work on portable or movable ones. It’s kind of adding a muffler to a generator, but it deflects the sound instead of absorbing it. So it keeps the sound within the box and prevents it from reaching you.
But keep in mind that using sound deflectors cannot be a permanent solution. So how to make your generator quiet? Use deflectors, mufflers, and other tools to make the generator quiet and get rid of the permanent noise.
5. Eliminating Exhaust Noise with Water
Yes, it’s actually possible to eliminate the exhaust noise in your generator with water. You only need two things for this- water and a hosepipe.
Take some water in a bucket. Insert one end of the hosepipe in the generator’s exhaust and the other end on the water bucket. So when the exhaust makes noise, the sound will be minimized by the hose pipe on the water bucket. This is an excellent idea to get a quiet exhaust for the generator.
The exhaust can increase pressure in the hose pipe. To eliminate the exhaust in the air, use a sharp pin or object to make a few holes in the pipe.
6. Using Rubber Legs
Rubbers are a great tool that absorbs vibrations. The rubber feet will absorb the vibrations created by the generator and reduce the noise quite a bit.
Generally, these feet are set on the bottom part of the generator. Soundproof mats or foams can also be used instead.
Keep your generator grounded and add more weight to it so that it can’t vibrate. Also, you can make a soundproof box to keep the noise away. A few more layers of foam can cancel the noise by a big margin.
Among the different ways, we’ve shown to reduce generator noise, which one did you like the most? Also, we hope now you know how to make your generator quiet as a cricket, right?
