Generator Noise and Vibration Control
The power produced by generators has become a welcome luxury in today’s world, providing unlimited convenience, productivity and even safety to homes, jobsites and businesses. The noise, however, created by a running gas-powered generator is often considered a great nuisance, drawing complaints and even raising health concerns.
REDUCING GENERATOR NOISE AND VIBRATION
All generators create sound yet the decibel levels among gas-powered generators range greatly from barely perceptible to ear-splitting volumes. On average, standby generators are quieter than portable generators. In the portable generator grouping, size can be a factor. Generally smaller generators are quieter than larger portable generators and inverter generators are the quietest.
Enclosures
In the effort to curb excessive volume, generators may incorporate several design features and technologies. Enclosures with acoustic insulation or sound-dampening foam, for example, are commonly used to absorb and reduce noise transmission. Another key feature are anti-vibration mounts. They work by minimizing vibrations to surrounding materials which in turn reduces sound. Anti-vibration mounts serve an additional purpose. They also help to eliminate the premature wear of components caused by excessive vibration. Vibration isolation pads are also used by some generators to further absorb and isolate vibrations. Low-tone mufflers are yet another tool some generators use to further reduce noise emissions. They may come as standard equipment with the generator or can be purchased separately and installed by a qualified technician.
Distance + Maintenance
Generator users themselves can take a few simple steps to help reduce noise and vibration. To lower volume levels, the easiest step is to place the generator further away from homes, buildings or crowds. For reducing vibration, the use of a vibration-resistant pad, tightening loose connections and lubricating components can make incremental improvements that help you achieve quieter operation with less vibration. When considering a generator purchase, using the information above can help you enjoy all the benefits of generator power while minimizing excessive noise.
