Quick Answer
Noise levels for propane generators are typically lower than gasoline generators. While propane generators can produce noise levels around 65 decibels, gasoline generators often reach levels of 80 decibels or more.
Propane Generators: Quieter and Cleaner
Propane generators are designed to run on a cleaner-burning fuel, producing fewer emissions and less noise pollution. This is because propane burns more efficiently than gasoline, producing less vibration and noise. For example, the Westinghouse WGen7500 propane generator produces a noise level of 65 decibels at 25% load, making it suitable for residential and RV use.
Gasoline Generators: Noisier but Cheaper
Gasoline generators, on the other hand, are often less expensive upfront but produce more noise and pollution. This is because gasoline engines are typically less efficient and produce more vibration, resulting in higher noise levels. For example, the Champion 100110 2500-Watt gasoline generator produces a noise level of 82 decibels at 25% load, making it more suitable for commercial or heavy-duty use.
Noise Reduction Techniques
To reduce noise levels even further, consider using noise-reducing technologies such as mufflers or acoustic enclosures. These can help reduce noise levels by as much as 10 decibels, making them more suitable for residential or noise-sensitive applications. Additionally, consider using a generator with a built-in noise reduction system, such as a noise-reducing engine or a quiet mode setting.
