Spending the weekend out in your RV with your family can be very therapeutic. That feeling of getting away from the big city, putting your feet up and just enjoying the peace and quiet is something we all need every now and then.
Well, That’s up to the moment you fire up the generator, right? and if you have been on camping trips in your RV before then you know how loud a generator can be and this is where you could do with a Quiet Box For A Generator “but” the question is do they really work?
That constant buzzing you get from the generator at night can be very annoying. However, there are some inverter generators that are extremely quiet that’s designed for (RVs) and for camping, producing under 60dBA of noise.
The bigger more powerful generators can be a lot louder and can be very annoying when running not just to you, “but for others around you” especially if you’re staying on a campsite.
Most people who tend to camp out in there (RV) use what’s called a “quiet box for a generator” to help minimize the noise “but” do they really work?
Yes, they do! A quite box for a generator can reduce the noise from high as 90dBA to levels closer to inverter generators that are between 48dB and 60dB. By using a quiet box for a generator this can reduce the noise and keep the dBA at a reasonable level that’s suitable for campsites.
However, there are some quiet boxes that can still make your generator sound loud typically if you’re using a metal box with no padding.
This is where you need a quiet box that uses materials like rubber and plywood boards that can absorb the noise making it quieter.
Quiet Box For A Generator
When looking for a quiet box for your generator there are some things you need to take into account, and what to avoid. For example, did you know using all metal boxes can actually have the opposite effect?

Rubber Absorption: When your generator is sitting in the quiet box with the engine running the unit does tend to vibrate slightly and by adding soft rubber, not will it stop the shaking but will also help reduce the noise.
Plywood Boards: Another great way to reduce the noise from your generator is by using plywood boards. To get the best possible results it’s better to have a custom quiet box made from scratch using this type of wood. However, you can build around your current quiet box using this wood just be sure not to block the exhaust and airflow.
Foam backer board: Another great way to reduce the noise from your generator, is to build your quiet box using foam backer board which is a type of plasterboard. It’s very cheap to buy and lightweight, making it easier to move around.
Insulation: By adding some standard loft insulation to your quiet box can help reduce the noise from your generator and like the form backer board it very cheap and lightweight.
Muffler: This option is great for those who already have a generator and just want to find ways to reduce the noise, and the best option for this is to buy a muffler for the exhaust. Have you ever heard a car with no exhaust? It’s the same priceable, and by adding an exhaust to your generator, this can dramatically reduce the noise level.
Exhaust Pipe: Did you know that changing the position of the exhaust pipe of your generator can actually help reduce the noise level. By having it pointing towards the sky rather than around the campsite actually works.
