Quick Answer
Generator noise levels are regulated by local authorities, typically measured in decibels (dB). In the US, the Federal Aviation Administration (FAA) limits generator noise to 60 dB or less at 50 feet for residential areas. Noise level measurements are often taken during the day and night.
Generator Noise Level Regulations
Generator noise level regulations vary by region and country. In the US, the Environmental Protection Agency (EPA) sets noise emission standards for new generators, while local authorities enforce noise ordinances. For example, in New York City, generators are limited to 50 dB or less during the day and 40 dB or less at night.
Measuring Generator Noise Levels
To ensure compliance with noise regulations, it’s essential to measure your generator’s noise level. This can be done using a sound level meter, which measures noise levels in decibels. For residential areas, a noise level of 60 dB or less is typically acceptable. To give you a better idea, here are some common noise levels: a whisper is 20 dB, a normal conversation is 60 dB, and a lawnmower is 90 dB.
Strategies for Reducing Generator Noise
If you’re concerned about generator noise levels or need to exceed regulatory limits, consider the following strategies: use a noise-reducing enclosure, install a muffler or sound-absorbing materials, or choose a generator with a built-in noise-reduction system. Additionally, consider using a generator with a lower horsepower rating, as these tend to be quieter than larger units. For example, a 10-kilowatt generator might be quieter than a 20-kilowatt unit.
