What Is The Average Decibel Level Of A Portable Generator?
The average decibel level of a portable generator can range from 60 to 90 decibels, depending on the size and type of generator. For comparison, a normal conversation between two people is around 60 decibels, while a lawnmower or vacuum cleaner can produce around 90 decibels. Prolonged exposure to noise levels above 85 decibels can cause hearing damage, making it essential to take measures to reduce the noise level of your generator.
It’s worth noting that some generators are designed to be quieter than others. Inverter generators, for example, are typically quieter than traditional generators, with decibel levels ranging from 50 to 70 decibels. However, even quieter generators can benefit from additional noise reduction measures, especially if you plan to use them in noise-sensitive areas or for extended periods.
How Do I Determine The Noise Level Of My Generator?
To determine the noise level of your generator, you can use a sound level meter, which is a device that measures decibel levels. You can purchase a sound level meter at most hardware stores or online. Alternatively, you can download a sound level meter app on your smartphone, although these may not be as accurate as a dedicated device. To take a reading, stand 3-5 feet away from the generator and hold the meter at ear height. Take multiple readings from different angles to get an average decibel level.
It’s essential to take readings when the generator is under load, as this will give you a more accurate representation of the noise level. You may also want to consider taking readings at different distances from the generator to see how the noise level decreases with distance. This information can help you determine the best placement for your generator and the most effective noise reduction measures to implement.
What Are Some Common Noise Reduction Methods For Generators?
There are several common noise reduction methods for generators, including acoustic enclosures, sound-deadening materials, and mufflers. Acoustic enclosures are specially designed boxes that surround the generator and absorb sound waves. Sound-deadening materials, such as acoustic foam or mass-loaded vinyl, can be applied to the generator casing or surrounding surfaces to reduce reverberation. Mufflers, on the other hand, are designed to reduce the noise emitted by the generator’s exhaust system.
Each noise reduction method has its advantages and disadvantages. Acoustic enclosures can be highly effective but may add bulk and weight to the generator. Sound-deadening materials are relatively inexpensive and easy to apply but may not be as effective as other methods. Mufflers can be highly effective for exhaust noise but may require additional installation and maintenance.
